Ultraviolet UV Protection
In addition, Transitions® Lenses work to protect you just like sun block protects your skin. Transitions® Lenses help preserve the health and wellness of your eyes by blocking 100% of harmful UV rays. Transitions® Lenses use special photochromic dyes which are activated when exposed to Ultraviolet of UV light. The activation of these dyes causes them to darken and to reversibly “tint” the lens. When exposure to the UV light diminishes, the lenses fade back to clear. As outdoor light conditions change, the level of darkness adjusts, creating just the right level of tint and allowing just the right amount of light to enter the eyes at any given time. This action allows Transitions® Lenses to help protect your eyes from the light you can see – reducing glare, diminishing eye strain and fatigue and enabling you to distinguish contrast more easily.
It’s important to note that no matter how light or dark your Transition® Lenses are, they are always blocking 100% of eye-damaging UVA and UVB rays. In other words, Transitions® Lenses provide automatic protection from UV rays in any environment, continually protecting your eyes from the light you can’t see while you enjoy comfort and vision quality in the light that you can see.
Transitions® lenses begin to darken the instant they are exposed to UV light. The greater the intensity of the UV rays, the darker the lenses become. The moment UV rays are no longer present the lenses immediately begin to fade back to their clear state. Most wearers report that the adjustment happens so quickly and smoothly, they are unaware of it. But, they remain aware of the visual comfort the lenses continue to provide in any light.
