Coatings applied to lenses of sunglasses block the sun's harmful UV rays to keep your eyes as healthy as possible.  Let's take a closer look at why these coatings are so important in the effort to combat sun damage.

Ultraviolet Protective Coating

The eyes are negatively affected when left unprotected against the sun's ultraviolet radiation. Excessive exposure to these harmful UV rays can lead to many problems with the eyes, like retinal damage and the development of cataracts. Much of the UV damage (some estimated upwards of 80 percent) to the eyes occurs at a young age so make sure your kids are wearing sunglasses when they go outside during the daylight hours. The best sunglasses will block out nearly all, if not all of the sun's harmful rays. Ideally, you will opt for sunglasses with a UVA / UVB rating of 100 percent.

Anti-reflective Coatings

The sun's glare and reflected light from other sources have the potential to sabotage your vision. Anti-reflective coatings will improve the look of your lenses as well as the quality of your vision. This coating will prove essential in your battle against the sun's glare. It is actually a combination of layers of mineral deposits applied to each side of the lens in order to block reflected light and reduce glare. When applied to sunglasses, anti-reflective coatings are typically used on only the back surface of the lenses.  Polarized sunglasses are best to block off glare from reflecting surfaces giving you optimal vision.

Clean Your Glasses Regularly

Be sure to store your glasses in a cushioned case and clean them with a microfiber cloth to preserve the integrity of their coatings across time. This way, the money you spend on high-quality lenses that protect your eyes won't go to waste.
