Clear indoors and at night, they darken in different light conditions to give you great vision clarity at all times. Transitions lenses also block 100% of harmful UVA and UVB rays so your eyes are protected from any potential damage.
Unlike other reactor light lenses on the market, Transitions XTRActive lenses activate when you are in the car. They not only provide you with UV protection, but also provide reduced glare from car headlights.
When photogenic lenses are exposed to UV light, trillions of photochromic molecules in the lens begin to change structure, causing the lenses to darken. Transitions patented technology integrates and constantly recalibrates and smooths so the optimal amount of light reaches the eye, no matter the weather.
In 1990 Transitions Optical were the first company to introduce a plastic photo-chromic lens which allows the lens to adjust and adapt to the change of light and to this day have continued this ground breaking innovation. To find out more about Transitions Lenses, click here.
