When it comes to lenses, you’ve got options: tinting, mirror coating, gradient, transition, polarized or non-polarized, and, of course — lens material.

We all are aware of the risks of sunburn and skin cancer from the sun's ultraviolet (UV) radiation, but did you know UV and other radiation from the sun also can harm your eyes?
Extended exposure to the sun's ultraviolet rays has been linked to eye damage, such as cataracts that can cause vision loss.
Moreover, new research suggests the sun's high-energy visible (HEV) radiation (also called "blue light") may increase your long-term risk of macular degeneration.
