Mirror sunglasses in wraparound frames were once popular in the ‘90s, but the mirrored appearance has an actual purpose. While a mirrored coating can be applied over any base color on plastic or glass lenses, the mirror sunglasses lenses reduce ten to sixty percent of the light reaching the eye. Although the dark color shades the eyes from UV exposure, those spending long periods of time outdoors need to protect their eyes from UV exposure. Although wraparound sunglasses often have mirror sunglasses lenses, other women’s and men’s styles use mirrored lenses, including the currently popular aviator sunglasses, shield sunglasses, and other classic styles designed to reduce UV exposure.
