Could a Low-Carb Diet Reduce Your Risk of Glaucoma?

A recent eye care study points to a possible connection between carbs and preventing glaucoma.

Recently, an eye doctor at the New York Eye and Ear Infirmary of Mount Sinai (NYEE) conducted a unique research study exploring the potential link between long-term dietary changes and preventing primary open-angle glaucoma (POAG). The study’s results indicated that if people at a high risk of developing glaucoma eat a diet that’s low in carbohydrates and high in fat and vegetable protein, they may lower their risk of this sight-threatening ocular disease by 20 percent. These results were published in Eye-Nature (July 22 issue).

Why are these results so significant?

Currently, glaucoma is the #1 cause of blindness in the United States, and primary open angle glaucoma is the most common type of this dangerous eye disease. Due mainly to elevated pressure levels inside the eye, POAG leads to optic nerve degeneration – causing vision loss.

Usually, patients experience no symptoms of POAG until the disease progresses, and visual problems motivate them to visit a nearby eye clinic for an eye exam. Regular eye exams by a qualified optometrist can detect the early signs of POAG way before vision loss occurs, but unfortunately, many people don’t visit an eye care provider until they notice a problem. In addition to routine eye exams, following a low carb diet may fortify people with another way to help prevent devastating vision loss.

How does the low carb diet affect eye health?

Eating foods that are low in carbohydrates and higher in fats and proteins causes the production of metabolites that are favorable for the optic nerve head, which is the specific site of damage in primary open angle glaucoma. Previous scientific studies have already linked this type of diet with positive effects on epilepsy, along with some promising results for Alzheimer’s and Parkinson’s disease.

While the low-carb diet cannot stop glaucoma progression in a patient who already has the disease, it may be a helpful way to prevent glaucoma in high-risk groups, such as people with a family history. Subsequently, the rate of vision loss due to glaucoma would be reduced.

Does a low-carb diet have the same effects as a ketogenic diet?

In the past, studies have demonstrated the protective effects that a ketogenic diet can have against neurologic disorders. (Ketogenic diets = extremely low-carb and higher-fat.). That’s because ketone bodies (energy compounds made by the body as it metabolizes fats) are used by the brain as a major energy source instead of glucose, and using more of these may enhance neurologic function and slow down neuronal degeneration. However, additional studies have shown that following a low-carb diet, not specifically ketogenic, may have similar properties for protecting against neurologic problems. And because a moderately low-carb diet is easier for most people to follow and doesn’t cause the same possible side effects of a ketogenic diet (e.g. headaches, abdominal issues, weakness, and irritability), it has been lauded as a more practical alternative.

How was the study on low-carb diets conducted?

The goal of the research study was to determine if following a low-carbohydrate diet for the long-term could have a positive impact on the optic nerve.

Your optic nerve transfers visual information from the retina to your brain, and it is located at the back of the eye. There is a large concentration of mitochondria (the major source of a cell’s energy supply) in the optic nerve. Because glaucoma is associated with dysfunctional mitochondria, researchers aimed to discover if substituting fat and proteins for carbohydrates would improve mitochondrial activity, preserve the function of the optic nerve, and prevent optic nerve degeneration in POAG (specifically, in a subtype of POAG with paracentral vision loss).

A large-scale study was formulated, involving 185,000 adults – female nurses and male health professionals between the ages of 40 – 75, between 1976 – 2017. Every two to four years, participants filled out questionnaires about what they ate and drank, as well as supplied information about their health condition. If they said they had glaucoma, the researchers followed up with their eye doctors to determine if they had POAG.

Data about the study’s participants was classified into three groups, based on how they achieved a low-carb diet:

  • Group 1 – Substituting animal-based fats and proteins instead of carbs
  • Group 2 – Substituting plant-based fats and proteins instead of carbs
  • Group 3 – Replacing carbs with high fats and proteins, regardless of the source

In the end, the results showed that people in Group 2 (increased plant-based fat and protein) were linked to a 20% lower risk of developing POAG compared to people who followed a high-carb diet. These findings suggest that vegetable sources may be beneficial than animal sources for a low-carb diet, with respect to lowering the risk of this subtype of open-angle glaucoma with paracentral vision loss.

What’s the take-home from this study?

First of all, eye doctors caution to remember that this was an observational study and not a clinical trial – so additional studies are needed to investigate the connection between dietary patterns and preventing POAG. Other issues, such as genetics, may also play a significant role. While it’s too early for optometrists to hang signs banning carbohydrates in their eye clinics, early findings do point to the eye care benefits of following a low-carb, plant-based diet. It’s time to stock up on legumes, avocados, nuts and tofu!

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Astigmatism, Pink Eye or conjunctivitis Myopia or Nearsightedness , Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next.

    • What exactly is glaucoma?

      Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

    • How do I tell that I am developing glaucoma?

      The real tragedy behind vision-stealing glaucoma is that most people afflicted with this eye disease do not even realize they have it. As a result, the condition goes undiagnosed and untreated, which too often leads to unnecessary blindness. Of the 2.7 million people in the United States with glaucoma, half are undiagnosed. Most are lulled into a false sense of confidence because glaucoma often displays no symptoms in its early stages. By the time it begins to affect vision, any lost sight is impossible to regain. The risk of developing glaucoma begins to increase dramatically at midlife, which is why everyone should have a baseline exam by age 40. The most important concern is protecting your sight. Doctors look at many factors before making decisions about your treatment. If your condition is particularly difficult to diagnose or treat, you may be referred to a glaucoma specialist. While glaucoma is most common in middle-aged individuals, the disease can strike at any age, with those having a family history of the disease is especially vulnerable.

    • If one of my parents has glaucoma, does that mean I will develop it as well at some point?

      Having a parent with glaucoma does not mean that the child will automatically develop the condition too. However, those people with an immediate family history (parents, siblings) of glaucoma are at more risk to develop this disease. Patients should have a comprehensive eye examination each year to evaluate the health of the eyes and to look for signs of glaucoma. Some of these signs can be an increase in the pressure of the eyes as well as changes to the appearance of the optic nerve. Many times there are no symptoms noticed by the patient. If there is suspicion of glaucoma, more frequent visits to the eye doctor along with additional nerve testing are often required.

    • How often should I have my glasses prescription checked?

      Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss.

4 Reasons Why Scleral Lenses Are a Big Deal

happy girl wearing contact lenses 640Scleral contact lenses have been called “life-changing” and “transformative” by patients who wear them.

What makes these contact lenses so revolutionary?

What Are Scleral Lenses?

Scleral lenses are contacts that vault over the entire cornea and rest on the white part of the eye (sclera). Their diameter is much larger than standard lenses, which adds to their comfort and compatibility with hard-to-fit eyes.

Here’s why they’re gaining popularity in the contact lens world and why patients and doctors are calling sclerals a big deal.

1. Sclerals are Ideal for People with Corneal Irregularities or Dry Eyes

There was a time when patients with corneal irregularities or severe dry eye syndrome weren’t able to wear contact lenses at all, due to the discomfort associated with direct corneal contact. Nowadays, patients with keratoconus, other corneal aberrations or dry eye can successfully wear scleral contact lenses and enjoy comfortable and crisp vision.

Scleral lenses are also great for patients with corneal dystrophy, high astigmatism, Sjorgren’s syndrome, corneal trauma and corneal ectasia, or who have undergone cataract surgery.

2. They’re Completely Custom-Made

Each pair of scleral contact lenses is custom-designed to gently and securely rest on your unique eyes. The fitting process for scleral lenses starts with corneal topography, where the optometrist creates a digital map of your eye’s surface. This information is then used to customize your perfectly fitted pair of sclerals.

3. They Offer Optimal Visual Clarity and Comfort

The liquid reservoir that sits between the lens and the eye helps enhance the visual optics of the lens. Moreover, scleral lenses are made of very high-grade materials and don’t place any pressure on the cornea, delivering ultimate all-day comfort. Many patients have reported that they comfortably wear sclerals for up to 14 hours a day, which is longer than the wear time for standard soft contact lenses.

4. They Promote Eye Healing

Scleral contact lenses protect the eye by surrounding it with an oxygen-permeable, liquid-filled chamber. This hydrating environment gives the eye the moisture and oxygen it needs to stay healthy and ward off outside irritants.

This can also explain why scleral lenses promote healing of the eye’s surface, whether after a corneal transplant or when recovering from a chemical burn or other eye injury.

If you or a loved one have been diagnosed with a corneal condition that prevents you from wearing standard lenses, consider scleral lenses. To schedule an appointment or to learn more, call The Scleral Lens and Keratoconus Center at Eyecare Greengate in Greensburg today!

The Scleral Lens and Keratoconus Center at Eyecare Greengate serves patients from Greensburg, Murrysville, Fort Allen, Export and throughout Pennsylvania.

Frequently Asked Questions with Dr. Chad Green

Q: #1: How long do a pair of scleral lenses last?

  • A: Scleral lenses can last 1-2 years before requiring replacement. Your optometrist will provide you with instructions on how to wear and care for your lenses to keep them feeling fresh and clean, day in day out.

Q: #2: Are scleral lenses expensive?

  • A: Just like any other customized product, scleral lenses tend to be more expensive than standard soft contact lenses. Although they have a higher price point, most patients who wear them will tell you that their comfort, visual clarity and stability make them worth the cost.

Why Does Outdoor Time Delay Or Prevent Myopia?

outdoor children 640Now that myopia (nearsightedness) is reaching epidemic proportions across the globe, it’s all the more important for parents to understand how myopia can impact their child’s future, and learn which actions they should take to protect their child’s eye health in the long run.

You see, myopia isn’t simply an inconvenience. Childhood myopia raises the risk of developing vision-robbing diseases like macular degeneration, cataracts, glaucoma, retinal detachment and diabetic retinopathy later in life.

Myopia develops as the eye elongates more than it should, causing light to focus in front of the retina instead of directly on it. This manifests as blurred distance vision and clear near vision.

While myopia is caused by a combination of circumstances, including genetic and environmental, a key factor comes down to the amount of time a child spends outdoors in the sunlight.

How Does Outdoor Play Affect Myopia?

Although researchers haven’t yet pinpointed exactly why “sun time” prevents or delays myopia, almost all agree that it plays a large role.

One possible reason is correlated to the brightness of the sun. Some experts have found that the intensity of the sun’s rays triggers a dopamine release in the retina which is thought to slow down the elongation of the eye.

Another theory holds that outdoor time encourages a child to shift their gaze from near objects to faraway ones. Excessive near work, like staring at a digital screen, is believed to be a driving force behind the stark increase in myopic individuals today.

Sending a child outdoors to play gives their eyes a break from focusing on their tablets, smartphones, homework, gaming and other near work.

Additionally, spending more time in the sunshine means more Vitamin-D production. Small-scale studies have found nearsighted people have lower levels of Vitamin D than those with normal eyesight. However, more research is needed to confirm this theory.

Here’s the Bottom Line

Childhood myopia increases the risk of developing sight-threatening eye diseases later in life. Parents should be proactive about their child’s eye health and do what they can to prevent myopia from developing or progressing at a rapid rate.

Even if your child doesn’t have myopia, encouraging them to play outdoors for several hours a day has been found to prevent the onset of myopia in certain instances.

So go ahead and give your child a water bottle, sunscreen, a pair of sunglasses—and send them out to play! Children aged 6 and up should spend about 2 hours daily outside in the sunshine.

But sun time alone isn’t enough to ensure the best possible outcome for their eye health. A myopia management program can help give your child the best odds of healthy vision for a lifetime.

To learn more about the myopia treatments we offer and schedule your child’s myopia consultation, call The Myopia Management Center at Eyecare Greengate today!


Frequently Asked Questions with Dr. Chad Green

Q: #1: What is myopia management?

  • A: Myopia management is the science-based method used to slow or halt the progression of myopia. There are several options available, and your optometrist will sit down with you and your child to discuss which treatment option is most suitable for your child’s needs.

Q: #2: Who can benefit from myopia management?

  • A: Myopia management treatments have been approved for children as young as 8 and can be used until early adulthood. Myopia management is great for children with low myopia but can also be effective for slowing myopia progression in kids and teens with moderate to high myopia. Contact us to find out whether your child is a candidate for myopia management.

Can Drinking Coffee Relieve Dry Eyes?

Can Drinking Coffee Relieve Dry Eyes 640Many of us enjoy a cup or two of coffee in the morning to keep our eyes awake and mind alert. But what else can caffeine do for our eyes?

If you suffer from dry eye syndrome (DES), characterized by dry, itchy and red eyes, you may have been advised by a friend or doctor to steer clear of caffeinated coffee due to its diuretic effect. Caffeinated beverages increase the frequency of urination, which leads to water loss. Yet some research suggests that a cup of caffeinated joe might actually promote tear production.

Below, we’ll explore scientific research that studies the relationship between caffeine consumption and tear film.

What is Dry Eye Syndrome?

  • Dry eye syndrome (DES) is an eye condition characterized by dry, stinging, red, itchy eyes. It can be caused by several factors: poor tear quality, insufficient tears, allergies, environmental irritants and excessive digital screen time. Left untreated, DES can lead to corneal damage and scarring and even permanent vision loss in severe cases.
    Certain foods and beverages have been shown to improve the symptoms of DES, like fish high in omega 3s, leafy greens, seeds, nuts, and…possibly coffee.

How Does Caffeine Consumption Impact Dry Eye Syndrome?

  • Caffeine contains a chemical called xanthine, which has been shown to stimulate tear production when applied topically to the eye. As yet, there is insufficient published research to confirm that ingesting xanthine provides the same tear-producing effect, though preliminary studies seem to suggest that it does.

 

A study published in Optometry and Vision Science found that drinking caffeinated beverages significantly increased tear production after 45-90 minutes. Interestingly, age, gender and body mass had no bearing on the outcome.

Another study, published in Ophthalmology, found similar results. Researchers measured the participants’ tear film twice: once after consuming caffeine and once after drinking a placebo. Their tear film was thickest after consuming caffeine, especially in those with a specific genetic makeup.

While both of these studies showed promising results, they didn’t include enough participants to accurately project the findings onto the general population.

If You Have Dry Eye Syndrome, We Can Help

Finding relief from dry eye syndrome relies on understanding the root cause of your symptoms. Only your eye doctor can diagnose the problem and determine the best treatment for you, whether in the form of medicated or lubricating eye drops, in-clinic treatments, personalized eye hygiene products like eyelid cleansing wipes, nutritional supplements and more.

Masks Can Cause Dry Eye Symptoms

How do masks lead to dry eyes?

The phenomenon of masks leading to dry eye is so widespread that a name for the condition has already been coined by some eye care providers: “Mask-associated dry eye,” or “MADE.” At our eye clinic near you, we’ve been seeing an increasing number of patients who visit due to stinging eyes, redness, and blurred vision – all classic signs of dry eye syndrome. While dry eye syndrome has always been a common reason to book an appointment with our optometrist near you, what’s new is that the dry eye symptoms seem to be caused by wearing masks.

How can you prevent your mask from causing dry eye irritation? near you in Murrysville, Pennsylvania

The phenomenon of masks leading to dry eye is so widespread that a name for the condition has already been coined by some eye care providers: “Mask-associated dry eye,” or “MADE.” At our eye clinic near you, we’ve been seeing an increasing number of patients who visit due to stinging eyes, redness and blurred vision – all classic signs of dry eye syndrome. While dry eye syndrome has always been a common reason to book an appointment with our optometrist near you, what’s new is that the dry eye symptoms seem to be caused by wearing masks.

If you’re wearing a mask and eyeglasses, every time you breathe it fogs up your lenses. Then they defog, only to fog up again with your next breath. Steamed-up glasses and the onset of dry eye symptoms is an emerging condition to be aware of. The main reason for promoting awareness of MADE is not to encourage anyone to stop wearing a mask, but rather, it’s to help people manage the eye irritation that may result – while continuing to don face masks.

When you breathe, you expel air over the top of your mask. This air flows over the surface of your eyes and can dry out the tear film that coats and lubricates your eye surface. It also speeds evaporation of tears.

In general, our eye doctor near you has found that mask wearing doesn’t trigger the onset of dry eye syndrome in people who don’t have it. Instead, it can worsen symptoms in people who already have the condition or are at high risk for it – such as people who spend a lot of time staring at computer screens. Nowadays, with all the working-from-home and Zoom meetings that occur, most people fall into the category of “at risk” for dry eye syndrome.

  • Make sure your mask fits properly. A poorly fitting face covering increases the chances that exhaled air escapes from the top opening and flows over your eyes. Push the metal strip at the top margin of your mask so it fits snugly over the contour of your nose and cheekbones, blocking airflow.
  • Avoid rubbing your eyes. This habit can lead to a long list of problems, including micro-scratches in your cornea and swelling that can exacerbate the symptoms.
  • Don’t ignore dry eye symptoms. Pay attention to how your eyes feel and seek effective treatment, such as lubricating eye drops, from our optometrist near you.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam.

  • My eyes are always burning and tired, what is causing this and what can I do about it?

    These are often signs of dry eye syndrome, a very common condition that affects many people over time. Women are generally more prone to developing these symptoms and aging is often a cause as well. Dryness of our eyes is often due to a decrease in the oil production in our eyelid glands which causes the surface of the eye to become irritated. Certain medications and health issues can also contribute to dryness. There is no true cure for dryness but many treatments are available such as the use of artificial tears, nutritional supplements incorporating Omega 3, prescription medications such as Restasis, and eyelid hygiene. No single treatment works for every individual so we customize treatments for each person and their specific condition.

  • What are the typical treatments used to help people suffering from Dry Eyes?

    Treatment for dry eye varies due to the severity and stage of the disease. Artificial tears can be helpful in the early stages. If artificial tears are not sufficient, we progress to a prescription medication such as Restasis or Xiidra. Also, lid hygiene, as well as omega-3 fish oil supplementation, can improve symptoms. Anti-inflammatory medications as well as punctal plugs are also available if needed for treatment.

  • Are there any day to day activities that can cause Dry Eye?

    Certainly, age, gender, and medications can be causative factors, but so can the work environment (dry offices or factories), weather/seasons, and
 geographical location.

How Much Exercise Is Recommended?

At our eye clinic near you in Murrysville, Pennsylvania, patients constantly ask about the bottom line: how much is enough exercise to reap the eye health benefits? According to the American Academy of Ophthalmology, you don’t need to run a marathon. Leading an active lifestyle, such as taking brisk walks, climbing up the stairs instead of using the elevator, and dancing can have a positive impact on eye health. In many cases, these types of exercise are enough to help lower blood pressure and keep blood sugars in control, which in turn helps prevent vision damage.

The Importance of Preventive Health Care

  • Along with exercising and maintaining a healthy, nutritious diet, the team at our eye care center near you encourages everyone to follow these preventive tips to keep your vision healthy:
    Get routine eye exams so your eye doctor can inspect for any early signs of disease, which will allow you to receive treatment as early as possible. Early detection is essential for effective treatments to slow or prevent damage to your vision.
  • Know your family eye history and share the facts with your eye doctor.
  • Wear sunglasses whenever you’re outdoors, regardless of the season. Dangerous UV rays are always out there.
  • Don’t smoke; smoking increases your chances of developing age-related macular degeneration and cataracts.
  • Eat nutritiously, including fruits and vegetables and foods high in omega-3 fatty acids, such as salmon.

I see fine. Why do I need to see an Eye Doctor?

Regular eye exams are the only way to catch “silent” diseases such as diabetes, glaucoma, and other conditions in their early stages when they’re more easily managed or treated. Many conditions can be discovered in a carefully planned eye exam. Those who consider mass-produced, over-the-counter reading glasses are truly doing themselves a disservice, both financially and medically. One-size-fits-all reading glasses not only do not work well for most people who have a different prescription in each eye, and/or astigmatism, or whose lens and frame parameters are not measured correctly, they bypass the opportunity to have their eyes checked for early detection of many manageable diseases or conditions. For those insisting on selecting glasses not measured specifically for their eyes, headache and eye fatigue are common symptoms.

What are cataracts and how can they be treated?

Cataracts are a clouding of the lens inside the eye. They are common with age, certain medications, and medical conditions. Patients usually feel like they are looking through a dirty window, cannot see colors the way they used to, or have increased difficulty with glare. Currently, the treatment is surgery to remove the cloudy lens. Stay tuned for medical advances in cataract treatment in the future!

What exactly is glaucoma?

Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

Living With Keratoconus | Kenneth’s Story

Kenneth’s Story 640From the time Kenneth was 11 years old, he wore glasses to correct his quickly deteriorating vision. He was always forced to sit at the front of the classroom and felt embarrassed by it. This time in his life marked the beginning of seemingly endless visits to various eye doctors to try and figure out what was causing his vision problems.

Four years later, at the age of 15, Kenneth was diagnosed with keratoconus, a progressive eye disease that affects the shape and condition of the cornea. Kenneth was referred by his ophthalmologist to an optometrist who [specializess] in treating keratoconus.

The optometrist explained that keratoconus is a condition that causes the cornea to thin and bulge out in a cone-like shape, leading to visual impairment. The early stages of this progressive eye disease usually cause mild to moderate vision problems that can be corrected with eyeglasses. But as the cornea’s shape continues to distort, glasses are no longer suitable and rigid contact lenses must be prescribed.

The optometrist prescribed rigid gas permeable contact lenses, which significantly improved Kenneth’s vision. But Kenneth sometimes found his contacts hard to manage, and even uncomfortable at times. People would tell him to just ‘switch back to glasses’ and ‘stop wearing the lenses if they give you so much grief.’

That wasn’t possible. He simply couldn’t see without the contacts.

Thankfully, before Kenneth’s condition progressed to the point where cornea surgery was required, new technology gave him fresh hope.

At the age of 20, Kenneth was fitted for scleral contact lenses for the first time. The day of the fitting was an emotional one for him and his family, as he was truly able to see the world around him in detail—and with great comfort.

Kenneth walked out of the optometrist’s practice, looked around, and saw leaves on the trees for the first time in 5 years. Prior to this, his perception of trees were brown stumps with green shrubbery—but never leaves.

He noticed that the cars driving past him on the street looked astonishingly clean. Nothing seemed faded anymore. Colors were vivid, lines were sharp.

The detail and clarity of each object were genuinely overwhelming for him. His mom, who also suffers from keratoconus, was overcome with emotion as she watched her son visually experience his surroundings in a whole new way.

From that day forward, Kenneth’s life changed drastically. His scleral contact lenses enabled him to function normally and achieve his goals. Wearing his sclerals allows him to work, exercise, socialize and be his authentic self.

Kenneth confesses that when he doesn’t wear his sclerals, his entire personality changes. He becomes timid, quiet and apprehensive.

Having keratoconus will no longer hinder Kenneth from living his best life, and it doesn’t have to hinder you or an affected loved one.

To a person with corneal disease, scleral lenses can be truly life-changing. If you or a loved one has keratoconus or other corneal irregularities, contact The Scleral Lens and Keratoconus Center at Eyecare Greengate today.

Q&A

Q: #1: How do scleral lenses work?

  • A: Scleral contact lenses are hard lenses that have a much larger diameter than standard soft contact lenses. They vault over the entire cornea and rest on the sclera (the white of the eye) so that no part of the lens is touching the cornea itself. The lens holds a reservoir of soothing and nourishing fluid between the eye and the lens, providing the best in visual clarity and comfort.

Q: #2: What other conditions do scleral lenses help with?

  • A: Any patient with irregular corneas can benefit from scleral lenses. They’re also suitable for patients with severe dry eye syndrome, as the fluid reservoir helps maintain comfort and ocular hydration. They’re also great for patients with very high refractive errors (high myopia, hyperopia, or astigmatism). Speak to your eye doctor if you think scleral lenses may be right for you.

Why Computer Use Can Cause Dry Eye & Eye Strain

Long Term Computer Use 640Nearly 60% of the Western world use some kind of digital device — a phone, computer, tablet, TV — for at least 5 hours a day. All that screen time can result in eye irritation and dryness. In fact, dry eyes and eye strain have become so common that researchers have coined a name for it: computer vision syndrome (CVS).

What is Computer Vision Syndrome?

Computer vision syndrome (CVS) is an eye condition commonly experienced after staring at a computer screen, at arm’s length or closer, for an extended period of time. It is characterized by eye strain and dry eyes.

Because more people work and study at home as a consequence of the COVID-19 pandemic, eye doctors are reporting a significant rise in the number of adults and children exhibiting these symptoms.

The symptoms of CVS include:

  • Red, watery eyes
  • Burning or stinging eyes
  • Sensitivity to light
  • Blurred vision
  • The feeling of having something in your eyes

Computer vision syndrome symptoms are similar to those found among dry eye syndrome sufferers, a condition that also tends to develop as a result of extended computer use when blinking is reduced. Blinking is critical for good eye health as it rejuvenates the tear film on your eyes, ensuring constant hydration and protecting them from damage.

5 Tips to Prevent CVS

Luckily, computer vision syndrome can be effectively managed with a few simple adjustments to your screen time.

  1. Take regular breaks. Follow the 20-20-20 rule to prevent staring at your screen for too long. Take a break from your computer or device for 20 seconds, every 20 minutes, and look at something at least 20 feet away.
  2. Adjust your angle. Make sure your screen is 20-28 inches from your eyes and that the center of the screen is 4-5 inches lower than eye level.
  3. Use a cool-air humidifier. A humidifier adds moisture to the air and prevents your eyes from drying out.
  4. Reduce glare. Your eyes work harder to read when there is glare reflecting off your screen. Make sure your screen is positioned in a way that prevents glare from windows and lighting. You can also add a glare filter for eye comfort.
  5. Get computer glasses. Computer glasses allow your eyes to focus on a computer screen with less effort and the blue-light filter may also reduce exposure to potentially harmful blue light emitted by digital devices.

By taking regular breaks from your screen, you give your eyes and body a much-needed rest. To learn more about computer vision syndrome and to receive treatment to alleviate dry eye symptoms and eye strain, contact The Dry Eye Center at Eyecare Greengate.

 

Frequently Asked Questions with Dr. Chad Green

 

Q: What’s the link between staring at a computer screen and dry eye?

  • A: Staring at a computer screen can reduce the number of times a person blinks by 30%. That’s problematic because blinking is essential for lubricating the eyes and keeping the protective tear film that covers the eye intact. If you find your eyes becoming irritated or uncomfortable at work, try to blink more, especially while using the computer and reading.

Q: Can blue light glasses help avoid computer vision syndrome and dry eye?

  • A: Spending long periods of time on a computer or device can negatively affect your eyes, potentially leading to computer vision syndrome and dry eye. Symptoms include blurred or double vision, headaches, eye strain, eye fatigue, sleep disruptions, and dry eyes. Computer glasses offer blue light protection by reducing the dangerous effects of blue light and the risks of computer vision syndrome.

A Guide to Scleral Lenses

Vision And Medicine Concept. Accessories For Contact Lenses: Con

Many people can’t wear standard contact lenses. This is especially true of patients with severe dry eye syndrome, keratoconus, irregular astigmatism, among other conditions.

That’s why eye doctors often prescribe scleral lenses to such patients. These specialized rigid, gas permeable contact lenses have a very wide diameter and extend over the entire corneal surface, making them effective and comfortable for people with irregular corneas.

At first, some patients may find scleral lenses to be difficult to insert and remove. However, after some practice, you’ll find it easy to care for your sclerals!

Safety and Hygiene for Scleral Lenses

Handling scleral lenses incorrectly can increase your risk of eye infection. Additional risk factors include improper lens cleaning, poor hygiene, and smoking. Therefore, it’s important to follow your eye doctor’s instructions on how to handle your lenses hygienically.

Before handling, inserting, or removing scleral lenses, make sure to:

  • Always wash your hands thoroughly with non-oily soap or antibacterial-based pump soap and dry them with a clean lint-free towel or paper towel.
  • Sit at a desk or table and place a lint-free cloth down to insert and remove lenses. Avoid bathrooms, as they often contain more germs than other rooms in the home.
  • Inspect your lenses for chips or cracks and protein deposits on the lens surface. If you notice any defects or are unsure whether your lenses are damaged, don’t wear them until your eye doctor has inspected them.

How to Insert Scleral Lenses

  1. Remove your scleral lenses from their storage case and rinse with them with saline. If you’re using a hydrogen peroxide solution, wait at least 6 hours from when the lenses were placed into the storage case for the solution to neutralize. Always rinse with saline before placing the lens on the eye.
  2. Either place the scleral lens between your middle, forefinger, and thumb — known as the tripod method — or secure the lens to a suction tool (plunger) supplied by your optometrist.
  3. Fill half the bowl of the lens with preservative-free saline solution to prevent air bubbles from forming between your eye and the lens. Insert the lens directly onto the center of your eye in a facedown position.
  4. Dry and wipe your lens case with a tissue and leave the case lid off to air dry.

How to Remove Scleral Lenses

There are two methods to remove scleral contact lenses: with your fingers, or with the aid of a plunger. First, to detach your scleral lenses from your eye, press firmly with your finger on your bottom eyelid just below the edge of the lens, then push upwards.

Method 1 – Manual Removal

  1. Try Scleral Lenses Thumbnail.jpg

    Insert a drop of preservative-free saline solution or artificial tears to loosen the lens.

  2. Look down onto a flat surface (a mirror or towel can be placed there).
  3. Use your middle finger to open your eyelid wider than the lens diameter.
  4. Apply pressure to the middle of the lid — as close to the lashes as you can — and push down on the eyelid to move your eyelid under the lens and lever it off the eye.

Method 2 – Suction Tool

  1. While looking at a mirror in front of you, hold your bottom lid open. Wet the tip of the suction tool to allow for better adhesion and attach it to the bottom of the lens.
  2. Using the suction tool, remove the lens by tilting the lens up and out of the eye.

How To Care for Your Scleral Lenses

The number one rule in contact lens care is always to follow the professional advice of your optometrist. If you need any clarification, always contact their office first.

Never ever use tap water in any area of lens care, whether to rinse or fill your lens case. Tap water contains a multitude of dangerous microorganisms, including acanthamoeba, that can cause a severe, painful, and sight-threatening infection. Be sure that your hands are fully dry after using a lint-free towel prior to handling your lenses.

Remove Before Going to Sleep

Most people can comfortably wear scleral contact lenses for up to 12-14 hours at a time. Approximately an hour before going to sleep is the best time to remove the lenses. If your lenses fog up in the middle of the day, it’s best to remove them and try various methods to clear up the fogginess before reinserting.

Use a Peroxide Cleaner

You can sterilize your scleral lenses by immersing them in 3% hydrogen peroxide. Over a period of 6 hours, the catalyst in the case transforms the hydrogen peroxide into water and oxygen gas. This gives your lenses a deep clean and removes the need to rub them, thus decreasing the risk of accidental breakage. Do not use the lenses until they have been immersed for 6 hours, as the un-neutralized peroxide will painfully sting your eyes. Leave the lens case to dry when not in use.

Use a Filling Solution That Is Preservative-Free

When inserting scleral lenses, use unpreserved sterile saline solution by filling the bowl of the lens upon insertion. Don’t use tap water or a preserved solution as these can lead to an eye infection.

Remove Debris Using Multi-Purpose Lens Solution

Once you’ve thoroughly washed and dried your hands, remove your scleral lenses and rub them for 2 minutes in a contact lens case filled with saline solution. This effectively removes microorganisms and deposits, lowering your risk of infection. While scleral lenses are strong, too much force or an incorrect technique can cause them to break.

After rubbing your lenses, thoroughly rinse them using the solution for 5-10 seconds. Then place them in a case filled with fresh solution and leave them to disinfect for at least 4 hours.

Routinely Clean and Replace Your Lens Case

Regularly clean and replace your lens case to prevent infection due to bacterial contamination.

It is recommended to clean the storage case on a daily basis and to replace it monthly or as advised by your eye doctor.

Your optometrist will recommend when to get a new pair of scleral lenses, and will advise you when to schedule follow-up appointments. Failure to show up for scheduled appointments can compromise the lenses’ efficacy.

At The Scleral Lens and Keratoconus Center at Eyecare Greengate, we can recommend the best wearing schedule for your contact lenses to ensure the highest level of comfort and visual acuity. Always follow the instructions provided by your eye care professional. Call to schedule an eye exam and a scleral lens fitting today.

Why Bother With Myopia Control?

Boy Trouble LearningMyopia control is a hot topic these days — and for good reason. More and more parents are providing their nearsighted children with myopia control treatments in hopes of slowing down the rapid progression of this very common refractive error.

Is myopia control worth all the effort? Why not just get new glasses every time your child needs a higher prescription? Is childhood myopia really that big of a deal?

Below, we’ll answer these important questions so you can make informed decisions and feel confident about your choices. If your child has myopia, contact The Myopia Management Center at Eyecare Greengate to learn more about how we can help.

Myopia Is Not Harmless

Myopia is far more than just blurry distance vision. What many don’t realize is that it can seriously impact a child’s long-term eye health.

A child with myopia is significantly more likely to develop sight-threatening diseases, such as glaucoma, cataracts, retinal detachment, and macular degeneration, later in life.

Because the cause of myopia is an elongated eye, the stretching of the eye takes a toll on the retina (the light-sensitive lining at the back of the eye). Over time, the stressed retina is more prone to damage and tearing.

Your Child’s Lens Prescription Matters

Suppose your child’s lens prescription is -3.00D (mild to moderate myopia). Although you may think that it’s too late for myopia control at this point, research suggests otherwise.

The level of myopia a child has is directly correlated to their risk of eye disease — the higher the myopia, the greater the risk.

A child with myopia that’s between -0.75D and -3.00 is more than 3 times more likely to develop retinal detachment in the future. That number triples for individuals with high myopia (-5.00 and above).

The risk of myopic maculopathy is also influenced by the level of a child’s nearsightedness. Children under -5.00 have just a 0.42% of developing this serious eye condition, but anything above -5.00? That risk level leaps to 25.3%.

Slowing down or stopping your child’s eyesight from worsening will greatly increase their chances of having a healthy vision in adulthood. Halting myopia as early as possible renders the best outcome.

Myopia Is On The Rise

This is the time to act. With myopia cases escalating exponentially, it’s expected that about half of the world’s population will be nearsighted by 2050, and about 10% of those individuals will have high myopia.

Offering your child myopia control now can potentially prevent them from being part of that 10% in 2050.

If your child has myopia or is at risk of developing it, we can help! To schedule your child’s myopia consultation, contact The Myopia Management Center at Eyecare Greengate today.

Q&A

 

Q: #1: How do I know if my child is at risk of developing myopia?

  • A: If one or both parents have myopia, a child is predisposed to becoming nearsighted. Other factors that influence myopia include excess screen time, not enough time spent in the sunlight, and being of a certain ethnicity (people of Asian or Pacific Islander descent have the highest risk).

Q: #2: What treatments are used for myopia control?

  • A: The 3 main treatments are atropine eye drops, orthokeratology (Ortho-k) contact lenses, and multifocal contact lenses. Your optometrist will help you decide which method best suits your child’s eyes and lifestyle.
