Lens Materials

Eyeglass lenses are made from different materials to serve different purposes.

Hi-Index/Ultra-thin Lenses: Revolutionary high-index lens materials that offer strong prescriptions in the thinnest, lightest lens available.  No more "coke-bottle" glasses!  There are various grades of high index depending on how thin you’d like your lenses.  They have the best optics for high prescription ranges.  Includes UV protection and scratch resistant coating.

Polycarbonate Lenses: The most impact-resistant material which is also thinner and lighter than standard plastic.  Good for all children, athletes or anyone who wants the safest lens available.  Has built in UV protection and scratch coating.

VISION SAFETY NOTICE:

Of all the materials that lenses can be made of, polycarbonate is the most impact resistant.  Plastic or glass lenses are less impact-resistant and can break into sharp pieces that can cause serious injury to the eye, or even blindness.  Most frames are not designed for protection.

If your occupation or recreational activities expose you to flying objects or physical impacts, you may require sports goggles or safety glasses with side shields.  We recommend polycarbonate lenses for children under 18 years of age and for any adult who wants the safest lens material available.

Plastic Lenses: Stronger than glass and half the weight.  Maximum comfort and durability.  Can be tinted to almost any color density but can scratch easily.

Transitions/Lenses that Darken: Photosensitive lenses tint automatically, adjusting to the intensity of light passing through the lenses. Tint darkens outdoors and lightens inside.  Also available in sunglass shades.  Provides excellent UV protection.  Available in glass or plastic.
