Polarized lenses have a unique chemical film coating that helps eliminate or reduce glare. Glare is caused when light from the sun is reflected off of water or a solid surface. Have you ever noticed when you are out at the beach or lake, the glare reflecting off the water causes blurry vision? When light is reflected off of water or solid surfaces, the reflected light shines back at your eye and is magnified which results in a glare. Polarized lenses filter the light that comes in from different angles and allow you view objects clearly. Without polarized protection, depth perception is reduced, distorted view and color perception occur, and in some cases, you could be temporarily blinded. Polarization is useful for many outdoor activities including driving, extreme sports, water sports, and fishing. Better yet, prescription polarized sunglasses are also an option for anyone who needs corrective eyewear. The benefits of polarized sunglasses are endless and can save your vision!
