When reading outdoors, protection is a must and annoying glare can really interfere with being able to read comfortably. Our reading sunglasses are photochromatic providing the versatility of adapting to light for your convenient indoor/outdoor use. Our optical quality lenses have most important UV protection and are anti-reflective coated to cut down on glare from the sun outdoors or indoors while working at the computer or any other glare inducing environment. You won't have to switch between indoor readers and ones for outdoors. What a breeze!
