We know that transition lenses react to UV exposure, but just how do we explain the change in color? Transition lenses incorporate trillions of photochromic molecules that activate when subjected to UV light. When the structure of these molecules changes simultaneously, this creates the darkening effect on the complete surface of the lens. Put them…

Encourage them to put them on in the morning when they get dressed and take them off during the night before each goes to bed. They shouldn’t pinch their ears or nose, or weigh down their face.

This may account for their apparent success in making office workers more comfortable. In NJ, our…
High Index lens were invented in 1990 to greatly help those with a higher prescription achieve a thinner lens, thereby improving the aesthetic look of the lens, along with the individual. High Index lens help bend light more efficiently than regular lens, so it enables the lab to help make the lens thinner. When the…
