Polarized Lenses Block Glare
Polarized lenses are helpful in blocking polarized light. This type of light is created by reflected light. When bright light bounces off of horizontal surfaces such as water, cars, snow, or the highway, it can cause intense glare. Bright glares make it difficult or impossible to see. Polarized lenses can be beneficial for certain situations, including driving, skiing, and fishing because they cut the scattered light causing a glare. Fishermen, for example, often use polarized lenses to help them see beneath the water and better locate fish. While most polarized lenses have built-in UV-blocking features, it is important to check the lens labeling to determine if the sunglasses offer full protection. Regardless of the type of sun protection chosen, the quality of the lens is important.
