Photochromic lens technology has been around for over 40 years. Photochromic lenses change from clear to dark based on the intensity of UV radiation. Remove the source of UV radiation from the lenses, and they return to their clear state.
The amount of photochromic reaction (how much a lens darkens) depends upon the intensity of the UV radiation present, combined to a lesser extent with the current temperature of the air. That means photochromics adjust automatically to indoor and outdoor light conditions. Photochromic lenses automatically adjust to outdoor lighting conditions by providing the right level of tint, and return automatically to their clear state; both indoors and at night.

Today’s lifestyles demand more from eyeglass lenses. Comfort, convenience, U.V. protection. It’s no wonder there are so many different types of lenses available. If you prefer lenses that are clear indoors and at night, but darken and adapt to changing light conditions outdoors, there are products like Original Transition’s lenses, which are an ideal replacement for clear lenses. If you’re among those who prefer an even darker lens outdoors at all temperatures, a lens that darkens moderately behind the windshield of a car and don’t mind a slight indoor tint, there’s Transition’s XTRActive Lenses. Really active outdoors? Special performance sun lenses such as Transition’s SOLFX Effects Dynamic Sun Lenses adjust both color and darkness to enhance performance in your favorite outdoor activities.
