|CR39 Transitions Lenses®|
At CR39 Transitions® Lenses contain light-sensitive molecules that darken and lighten according to the intensity of ultraviolet light. Recent advances in Transitions® technology ensure that they perform consistently across a wide range of temperatures and climates.
The greater the intensity of the UV rays, the darker the lens becomes. The moment the UV rays are no longer present, the lens begins to fade back to almost clear. Transitions® Lenses do not change while driving in a car. All Transitions® lenses come with 100% UV protection.
