Photochromic
Lenses Another very important misperception that should be addressed is whether or not photochromic lenses darken behind the windshield of a car. Some manufacturers claim partial activation, but none perform like a true sunglass because the UV necessary for activation is blocked by the windshield. For those patients who require dark sunglasses when they drive, a regular prescription sunglass is the best option. At night, most photochromic materials are clear, allowing for safe driving after dark. However, photochromic lenses that are tinted for maximum sun protection may not be suitable for night driving. Keep this in mind when you�re recommending photochromic lenses.If you properly explain how specific photochromic lenses work � whether for viewing comfort or as a true sunglass outdoors - their new eyewear will totally live up to their expectations. The technology of
photochromic lenses is also worth describing. People who wore photochromic
lenses a few years ago and didn�t like them may not be aware of the
recent improvements made in these products. You should make a point
of this. Use patient-friendly, non-technical terms such as �sun-sensitive�
to describe how photochromic lenses perform. Everyone likes to know
they are getting the �latest and best� new products. The technological
improvements in today�s photochromic lenses may help influence the decision
to try them.
