OPTIONAL LENS TREATMENT OPTIONS
Scratch Protection Coating
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.
Anti/Reflective Coating
Special anti-reflective (AR) 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.

PHOTOCHROMIC LENSES
Photochromic lenses are eyeglass lenses that darken automatically when exposed to sunlight, then fade back when you return indoors. In most cases, photochromic lenses are clear (or nearly clear) indoors and transition from medium to dark outdoors.
POLARIZED LENSES
In sports and other outdoor leisure activities we react to what we see. We see by virtue of the light that enters our eyes. Without good sun wear, brightness and glare will diminish our best efforts. Glare results in a loss of visual performance, which is produced when an object or light source in the field-of-vision is brighter than the amount of light to which the eyes are adapted. Most tinted lenses will provide some absorption to dampen brightness, but only a polarized lens can effectively eliminate blinding glare.
