Top Sellers in Sunglasses Product Description Uvex MP-VI Melanin Polarized Sunglasses offer ultra-effective eye protection from the sun. These glasses reduce the risk of age-related cataracts and macular degeneration, and also work to reduce eye fatigue and glare. The lens' main protective component is melanin, a naturally-developed and powerful defense against sunlight damage. Uvex's patented process formulates melanin into a matrix of poly carbonate, creating the ultimate lenses for sun protection. These lenses are also polarized, adding additional protection against reflected glare, which is particularly useful when near snow or water.
