Photochromic lenses use the power of the sun’s ultraviolet rays to darken your lenses. They are highly useful for someone who doesn’t want to switch between their regular glasses and their prescription sunglasses all the time. It used to be that the lenses didn’t get very dark or took a long time to transition between clear and dark, but technological advances have greatly diminished those issues. It is true that some of the products do not get quite as dark when you are in the car with the windows up as they do when you are out and about, however with the newer generation of Transition brand lenses, this has been greatly improved. Please feel free to call our office or stop by for a demonstration of these remarkable lenses.
