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.

 
     
 

Photo Chromatic

 
 

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 board certified 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.

 
     
 

Anti Reflection

 
 

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.

 
     
 

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.
