Unlike traditional flip-up designs that only filter light approaching from directly ahead, the SideKick features a wrap-around lens design that filters out light that can enter your field of vision from above and the peripheral. Engineered to withstand harsh treatment during daily use, each polycarbonate filter is optically correct, scratch-resistant, lightweight, and extremely durable.
The Smoke absorptive filter, great for general use, reduces light intensity and provide true color definition. It transmits 15% of visible light and provides 100% UVA/UVB protection. The Medium size fits well with most wider prescription eyewear frame designs.
