What is the purpose of backside anti-reflective coating?
Backside anti-reflective (AR) coating significantly minimizes light, glare, and UV that can reflect off the back of the lenses. Bounce-back glare can be distracting at best and could significantly impact your vision at its worst. Additionally, the light that reflects off the backside of the lenses can include harmful UV light. Rio Ray Sunglasses come standard with backside anti-reflective coatings to provide you with comfort and clarity.
