Xperio UV™ polarized sun lenses provide sharp outdoor color perception all while protecting your eyes with a superior quality lens. A tough, scratch-resistant coating is applied to both sides of the lens, reducing damage to the surface of the lens.

They are two completely different things. While UV protection sunglasses protect your eyes from harmful sun rays, polarized lenses reduce the glare that causes you to squint in the sunlight.

Polarized, or anti-glare, sunglass lenses reduce light glare and eyestrain. Because of this, they improve vision and safety in the sun. When working or playing outdoors, you can become frustrated and even temporarily blinded by reflected light and glare.

Polarized lenses, as we learned, don't protect from UV rays, but they do have a coating applied to them that filters light and reduces glare. This type of lens can help people see more clearly in the sun by reducing glare that often comes off water, car windows, sun, and more.

Is UV coating waterproof? No, UV coating is not waterproof, but it is water resistant. UV coating shouldn't be confused with other types of paper finishing processes, such as aqueous coating and lamination.

A polarized film consists of special molecules running in horizontal parallel chains. This film acts as a filter, blocking out light that bounces off reflective surfaces such as water, road surfaces, or water vapor in the air around you.

Benefits of Polarization For most people, the most obvious benefit of polarized prescription sunglasses is their ability to prevent glare. However, in addition to their glare-blocking ability, polarization can also: Prevent wrinkles around the eyes by reducing squinting. Increase visual contrast.

Polarized lenses will not protect your eyes from UV damage more than standard 100% UV lenses. However, they can give you clearer, more accurate vision and alleviate some eye strain. If you find yourself squinting a lot, even when you're wearing sunglasses, consider investing in polarized sunglasses.

Polarized lenses not only reduce glare, they make images appear sharper and clearer, increasing visual clarity and comfort.

Polarization has nothing to do with UV light absorption, but many polarized lenses are now combined with a UV-blocking substance. Check the label to make sure the lenses provide maximum UV protection. The same goes for lens color and tint, lens darkness, and mirror coating.

Because sunglasses lose UV protection the more you wear them in the sun, the answer to "how often should you replace your sunglasses" depends on how frequently you wear them. If you find that you wear your sunglasses about two hours a day, you should replace them every two years.
