Yes, backside anti-reflectoin lens coating is a smart choice for all prescription sunglasses. In addition to offering UV protection, a important feature and benefit of prescription sunglasses is to reduce light glare and eye strain.
A backside anti-reflection lens coating minimizes the amount of light (entering from behind) that bounces off the inside of the lens and into the eye. This reduction in glare and eyestrain maximizes the benefits of your eyewear investment to you, your vision, and overall wellbeing.
