Mirrored sunglasses for men and women have a thin reflective metallic layer on the outside of the lenses that reflects glare away from the sunglasses rather than letting it in, reducing the amount of light entering the eyes.  The mirror coating decreases the amount of light passing through the tinted lens by a further 10–60%, making it especially useful for conditions of sand, water, snow, and higher altitudes. Mirrored sunglasses deter glare and defend your eyes against UV rays. They are stylish and enhance your color recognition abilities at a whole new level
