Photochromic Lenses

Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Some major brands of photochromic lenses, such as Transitions lenses, block 100% of harmful UVA and UVB rays.

On the pro side, since the lenses automatically adapt to light conditions, they reduce eye strain and fatigue indoors and squinting in sunlight. These rapidly changing lenses can also lessen glare by regulating the amount of natural light you are exposed to – the degree of darkening depends upon the amount of light. For those versions of photochromic lenses that protect the eye from harmful UV rays, you’ll lower the risk of cataracts and other age-related eye issues. They are available in most lightweight materials, work with single, bifocal and progressive lenses, and provide wearers with crisper vision and colors will appear more vivid in sunlight.

The biggest con is that they generally don’t work in a car because the windshield blocks the UV rays that are necessary to initiate the lenses’ darkening mechanism. However, if you drive a convertible like our Manager Lacey Mielcarek, you can ignore this point.
