Originally known as fishing sunglasses, Polarized Sunglasses reduce unwanted glare from reflective surfaces and increase visual contrast. Water, glass, hoods of cars, wet roads and anything that has a flat reflective surface is where you will see the benefit in having a pair of Polarized Sunglasses. Polarized Sunglasses have the same UV400 protection as non-polarized lenses. Additionally, polarized lenses are manufactured to selectively reduce glare whereas standard sunglass lenses will only reduce overall brightness. Wherever reflective glare is frequently experienced, Polarized Sunglasses will increase visual contrast, depth perception and reduce the need for squinting eyes.
