Fossil Sunglasses FOS 3090/G/S 807

1.67 Thinner Lens is a high index lens that is thinner and lighter making it ideal for higher prescriptions.

Basic lenses are polycarbonate (impact resistant) lenses with an anti-reflective coating.

Blue Block lenses are clear (indoors and out), providing protection against harmful high energy blue light. This can reduce headaches, increase comfort and is especially helpful for those of us who spend a lot of time on computers and other devices. Recommended for all ages.

Polarized lenses reduce glare and provide the most comfort and visual clarity in bright light.

Photochromic lenses will turn dark (resembling sunglasses) in sunlight and become clear again when indoors.
