Plastic lenses are great for prescription sunglasses due to their tintability factor. The lens is light weight compared to glass, and may be made in just about any prescription.

Polycarbonate lenses are the most impact resistant material. Up to 20% thinner and stronger than plastic. They are lightweight, have built in UV protection, and recommended for children, sports, as well as rimless frames. Originally used primarily for industrial safety glasses, they are now used for children, sports wearers, or anyone requesting greater impact resistance in their lenses.

Up to 30% thinner than Standard Plastic CR-39 lenses. Great for high prescription. Lighter in weight, these lenses also come with a built in UV protection.

Up to 42% thinner than standard plastic CR-39 lenses. Using a higher index of refraction than plastic or polycarbonate, high prescriptions no longer mean thick chunky lenses that can only be glazed into heavy frames. Lighter in weight and thinner, these lenses also come with a built in UV protection. Great for high prescription.

Polycarbonate lenses are the most impact resistant material. Sun-Sensitive Lenses are also called “transition” or “photochromic” lenses. They darken to 70% tint in direct sunlight, lighten to 5% tint in shade. Take both qualities together and you have a durable impact resistant transitional lens. This lens will allow you to do some reading outdoors during a nice sunny day.
