Lens tint affects glare and the ability to see colors and contrasts. Factors such as long hours in varying light conditions and time spent around reflected light off water, roads and other surfaces that can reduce performance need to be taken into consideration. The right lens tint enhances depth perception and reduces eye fatigue as well as minimizes color distortion and maximizes visua.

Index

Lens index is a number that describes how thick or thin your

lenses are. The higher a lens' index is, the thinner it becomes.

Higher prescriptions require higher index lenses, while lower

prescriptions require lower index lenses.
