What advantage do polarized sunglasses have over ordinary sunglasses?
top The answer to that question is glaringly obvious. Polarized sunglasses reduce glare! Polarized lenses work great in most conditions. A polarized lens filters scattered and reflected light. For example, if you look at water with a standard lens, the surface of the water is reflecting light from all different directions so it’s difficult to clearly see an object under water. Polarizing the light filters those reflected rays so you can see below the surface of the water. Beyond water light is reflected off most surfaces. This reflected light is in the form of glare. If you are squinting then you are straining your eyes in order for you to see better. This is the eyes natural defense to reduce glare. Squinting fatigues the eyes and causes unnecessary strain. Polarized lenses reduces this glare and enhances your visual acuity, letting you see better. A non polarized lens tries to achieve this by adding a mirror. Mirrors are an ineffecient means of attempting to reduce glare. Coatings ca
