Fit over sunglasses with polarized lenses. Light, comfortable, and practical to wear over your spectacles. Polarized lenses will protect from UV and reduce glare, improving contrast when depth perception. This is very important and useful while driving, on the water, skiing, on the beach, and in many other occasions.
Polarized sunglasses first became available in 1936, when Edwin H. Land began experimenting with making lenses with his patented Polaroid filter.
Polarized lenses are made of special polarized sheeting, to reduce glare caused by light reflected from polarizing surfaces such as water. Polarized lenses are especially useful when driving, skiing, fishing, doing water activities, on the beach, and more.
Polarized lenses also provide the ability to see beneath the surface of the water eliminating water reflections.
