What are transition lenses?
Transition lenses, also known as photocromic lenses, are ones that change color depending on whether you are indoors or outdoors, day or night. They are made the same way regular lenses are made, but with an additional polymer film that helps facilitate the darkening of the lenses to the correct tint. These lenses can be fitted to just about any frame you like.

How do transition lenses work?
Once you head outdoors during the day, the tint automatically begins to occur. You may notice that indoor lighting does not have the same effect, this is because the lenses are triggered by the ultraviolet rays of the sun. Once the sun hits the lenses, they begin to tint to provide better protection for your eyes.

How long does it take for transition lenses to become tinted?
The lenses take about 15 minutes to make a full transition into the protective tint. The same goes for when you go back indoors, when the lens will return to its clear form.

Are transition lenses as effective as regular sunglasses?
Yes! One of the benefits of transition lenses is that you essentially get a two-for-one deal, getting a pair of designer eyeglasses and sunglasses in one chic frame.  They provide the same protection from harmful UVA and UVB rays as a pair of your normal sunglasses do, but with the advantage of not having to lug around a second pair of glasses!

Who should wear transition lenses?
Transition lenses may be most beneficial to those who spend a lot of time outdoors, such as those who work outside, athletes, or even those who just like to get some sun on the beach. This is particularly helpful to wearers who enjoy physical activities, as there is no worry about what you’ll do with the other pair of glasses in the meantime.
