Light Reactive Variable Tint Lenses
Light Reactive Lenses or Variable Tint lenses automatically adjust to your changing light environment, continually providing you with the optimal amount of lens tint.
When inside, the lenses are clear similar to standard lenses. But when you go outside, they react to ultraviolet light, automatically darkening, transforming them into sunglasses.
These lenses are scratch resistant and also include the additional benefits of providing UV protection for your eyes.
Having a pair of Light Reactive Variable Tint Lenses may eliminate your need for more than one pair of glasses for most of your normal activities.
