Cut down on the Scratches
Crizal lenses are designed with two-sided scratch resistence, making them tough, durable and long lasting.

For Work & Driving
In clinical studies, Crizal lenses were proven to dramatiacally reduce eye fatigue caused by light reflection that cause glare.

Reflections Won't Reflect on You
Crizal lenses greatly reduce the reflections other people see on your glasses. So your eyes come shining through, no matter the light conditions.

Crizal is Easy
Fingerprints and smudges are challenges for other non-glare lenses. But Crizal features an advanced hydrophobic property that makes cleaning a breeze.

Varilux
Since that time Varilux has continued to innovate and set new standards of performance in vision care.

Progressive lenses, sometimes called "no-line bifocals", are a type of eyeglass lens used to provide visual correction for a common condition called presbyopia. Varilux progressive lenses enable you to see near, far and everything in between.

Varilux meaning "variable light" was named to demonstrate the progressive, or variable, power of the lens. Not only is it the first progressive lens ever designed, Varilux continues to be the #1 prescribed progressive lens by eye care professionals around the world. In fact, every minute there are 20 new Varilux wearers worldwide!

Aspheric Lens
These new lenses provide special visual and cosmetic benefits for stronger corrections and increased edge to edge clarity. Flatter than conventional lenses, aspherics eliminate the "bulgy" appearance of strong plus lenses (far-sighted corrections) and greatly enhance the appearance of finished eyewear. Persons with strong nearsighted corrections also benefit from thinner, lighter weight glasses when their lenses are aspheric. Because aspheric lenses are positioned closer to the face, there is less eye magnification with farsighted corrections and less "small eyes". look with nearsighted corrections. Aspheric lenses are often made of high index materials for the ultimate in thin lenses.

Photochromatic
These are lenses that darken as you go from indoors to outdoors. They are available in all lens materials. They darken to moderate shades of brown and grey. Have our optician show you a demonstration of these lenses.

Polarized
These are the most superior sunglass lenses that eliminate reflective glare. They are specially appropriate for driving, as well as fishing, hunting, and all types of outdoor activities. Ask for a demonstration.

Non-glare Lenses
Special anti-reflective coatings are now available for spectacle lenses, much like those used for fine camera lenses. These coatings are particularly effective for reducing eye fatigue for computer operators and anyone driving at night. And, of course, AR lenses enhance appearance by removing all distracting reflections. At Eyecare Greengate, we recommend all glasses have non-glare lenses.

Scratch Resistant
Light weight hard resin lenses can be more easily scratched than glass lenses. Special coatings have been developed to help protect lenses from normal scratching. The modest additional cost for such scratch coating is usually a prudent investment.

UV Protection
It is generally accepted that the ultraviolet rays in sunlight pose potential harm to the eyes. Special treatment is available for hard resin lenses that completely blocks hazardous UV light. Lenses like polycarbonate and high index include built-in UV protection at no extra cost.

Single Vision Lenses
Single vision lenses function as all purpose glasses for persons who have normal accommodation. Persons who normally wear bifocals or trifocals can use single vision for distance or near lenses. Single vision lenses can also function as occupational glasses for certain types if work. Single vision lenses are available in all lens materials.

Flat Top Bifocal
This lens is available with the lined bifocal portion made in a variety of widths to help with various close-up requirements. Bifocals are made in every type if lens materials.

Trifocals
Trifocals come in a variety of designs. The added segment provides clear vision at arm's length focal distance, which is the area that is usually blurred for line bifocal wearers. Trifocals are available in all lens materials.

Progressive
This is the lens with no visible lines. Correct vision for all areas of viewing from distance to near, including the intermediate or arms length focal distance. Progressive lenses offer clear and continuous vision making this lens similar to the function of the eye itself. Progressive lenses have the cosmetic advantage of appearing to be single vision so it is never revealing the user wears bifocals. Progressive lenses are available in all lens materials and aspheric design. Because of their many benefits, these are the preferred lens choice for bifocal and trifocal wearers.

Wave Front Technology Leneses
Beginning in late 2005, eyeglass manufacturers began announcing availability of new lens designs based on wavefront technology as a way to greatly reduce visual distortions and improve lens clarity. Different companies claim unique advantages to their design technologies.

Additionally, many new technology eyeglass lenses in recent years have started incorporating digitalized corrections on both the outside and inside of lenses to achieve better focus. With the extra benefit of wavefront analysis included, these new technology lenses often can achieve much finer precision in vision correction than conventional lenses. Wavefront lenses from iZon are being marketed as a way to achieve crisper vision for nighttime driving and providing higher definition vision in the daytime, compared with conventional lenses. Among the first companies to promote wavefront technology in new lens designs was Essilor of America with Varilux Physio and Varilux Physio 360?.

Proprietary Essilor wavefront technology known as W.A.V.E. used in Varilux Physio lenses helps eliminate certain vision distortions commonly associated with or not corrected by previously available, conventional progressive lenses.

Progressive lenses are for older people who have presbyopia, a vision defect that with aging reduces the ability to focus at all distance ranges. Because of wavefront enhancements, Essilor officials say the transition between near, intermediate, and distance zones with Varilux Physio progressive lenses, as an example, is much smoother. In addition, the company claims a 30 percent increase in contrast sensitivity with these lenses, enhancing ability to better distinguish colors and details.

Occupational
Many occupations impose demanding visual requirements on those who wear bifocals or trifocals. Special occupational designs are available to solve these special needs. If the visual requirements of your job falls into this category, let us know and we'll explain what will work best for your individual needs.

Plastic (Hard Resin)
Conventional hard resin lenses are half the weight of glass lenses and can be tinted to almost any color or density. Hard resin lenses are more easily scratched than glass but can have an optional scratch protection applied. More impact resistant than glass, hard resin lenses do not require heat treating.

High Index (Lighter, Thinner)
Modern technology has created lenses that bend light differently so that stronger corrections are thinner than when made in conventional materials. These lenses are deigned for stronger corrections and are more attractive because they are lighter and slimmer. High index plastic uses less material so they are often lighter in weight. High index lenses absorb all harmful UV light and can be tinted in any shade or color.

Polycarbonate
Polycarbonate lenses are the most impact resistant lenses available and are always the lens of choice for young people and active patience. Polycarbonate lenses are usually the lightest, most comfortable lenses. They absorb all harmful UV light and can be made with ultra thin edges because of their unique strength.

Trivex

Glass
For years glass was the only lens material available offering superior optics. It is the most scratch-resistant material, the primary disadvantage to glass is its weight, generally twice that of hard resin. Glass lenses are heat or chemically treated to increase impact resistance.
