You’ve probably heard of polarized sunglasses before, but maybe you’re wondering how they actually work and what they do. We’re sure you have a number of questions about these unique sunglasses and their benefits, so check out all the information below.
So, why are polarized lenses so awesome? Polarized lenses are coated with a special chemical film that helps reduce glare. Glare is caused when light from the sun is reflected off of water or a solid surface. By neutralizing glare, polarized lenses help you see objects more clearly, and also help reduce the harmful effects of UV light.
The sun’s rays reflect light in every direction, so when a ray hits a flat surface, the reflected light shines back at your eye and is magnified, causing glare. Glare is a real buzzkill. It reduces your depth perception, distorts your view and color perception, and can even temporarily blind you. Not cool.
Regular sunglasses are designed to only reduce the amount of light that is transmitted through the lens horizontally and vertically. But the chemical filter on the lenses of polarized sunglasses is designed to absorb horizontal light waves, while still allowing vertical waves to pass through. Because light only travels in one direction through polarized lenses, glare is eliminated.
While tinted sunglasses are great for reducing brightness, they don’t eliminate harsh glare like polarized sunglasses. Don’t let darker lenses fool you into thinking they offer more protection from UV rays, either. The darkness of the lens does not accurately represent the lenses’ ability to block UV rays.
Always check the label on your lenses to see what level, if any, of UV protection they offer. Also, remember that dark sunglasses without UV protection will cause more damage to your eyes than not wearing sunglasses at all. Darker tints can cause the pupil to dilate, letting more UV rays into the inner part of the eye.
For years, boaters and fishermen have reaped the benefits of wearing polarized sunglasses. More recently, however, the benefits of polarization have been embraced by a variety of other outdoor sports enthusiasts and those who enjoy general outdoor recreation. Water-sport athletes, golfers, cyclists, and joggers can all benefit from sunglasses with polarized lenses.
