React Photochromic

D'Arcs React Photochromic lenses adapt to changing light conditions. As the sun gets brighter and the eyewear is exposed to a higher level of UV, the molecules in the lens change shape causing them to absorb more light. No matter what light environment you encounter the lenses will adapt and darken to give you the appropriate amount of clarity your eye need. They provide 100% UV protection and are optically correct.
