Maui Jim and Costa have long made polarized sunglasses for the specific purpose of reducing glare that comes off the water. But polarized sunglasses aren't just for fishing and water sports. Ray-Ban—a fashionable choice for keeping your eyes comfortable and safe in bright light conditions—is the most popular maker of polarized sunglasses at FramesDirect.
Polarized sunglasses are fitted with lenses treated especially to realign incoming horizontal light, thus reducing glare, improving contrast, and relieving eye strain.
No, polarization by itself does not protect your eyes from harmful UV rays. According to the Glaucoma Research Foundation, "polarization is unrelated to UV protection, so you still need to ensure UV absorption of the lenses.” Fortunately, most quality glasses that feature polarized lenses, also come with protection against ultraviolet rays.
Polarized lenses are created with specially designed filters that allow indirect rays to pass through instead of laying on top of the lens itself; the result is enhanced contrast and elimination of reflected glareno matter where the glare is coming from, the filter will stop it from hurting your eyes.
On the water you'll experience glare even when you're wearing sunglasses. This is not a direct ray, but a ray bouncing off the water. It can be intense at times, especially for people with light sensitivity. Many types of sunglasses and prescription glasses will reduce eye strain, but polarized sunglasses relieve the strain associated with horizontal glare from the sun's rays. So the answer to the question, How do polarized sunglasses work?, is by eliminating the glare from beneath us.
Essentially, there are two types of polarized lenses: 0.75 mm lenses and 1.1 mm lenses. The different thickness of the polarizing film used can improve the durability of the lenses, since it is placed on the outside of the glass and protected with a scratch-resistant coating. The thinner, 0.75 mm lenses are good for most casual sports where there's no risk of impact. The 1.1 mm layer provides additional strength that is useful in sports where impact may occur. The thicker film, however, does not make glasses of this type any better when it comes to reducing glare.
