Glass Photochromic Polarised
A glass lens provides the greatest optical clarity in polarised sunglasses and is also a perfect medium for a photochromatic lens. The photochromatic lens adjusts naturally to any changing light conditions in your environment, while still blocking 100% of the suns harmful UV rays. Without getting too technical (see our Tech Stuff for that), the high density of a glass lens makes it the most scratch resistant of all lens material.
