Ray Ban Sunglasses Lenses
Eliminate Glare by Choosing the Correct Lens
Glare is difficulty in seeing due to intense light, whether reflected or direct. At the beach, on the slopes, on the water, on the road, anywhere outside you are subject glare. Glare will lead to can impair safety, where if you're driving, whether in the daytime or night, a bright glare can interfere with your vision enough that it can cause an accident. Glare is also a major problem to those who have had eye surgery, have eye issues or naturally fragile eyes.
Sunglasses with polarized lenses have an especially laminated surface that are made up of vertically aligned stripes. These vertical stripes will permit only vertically polarized light to move thru the lens and into your eyes, this is important because glare is horizontally polarized and so will not pass thru polarized lenses and reach the eyes. So, during recreational sports that involve being on or near water, the reflected glare from the water is really reduced and will allow you to see clearly into the water. If driving, less glare from the sun will mean less fatigue and allow you to drive longer. On the ski slopes, polarized lenses in sunglasses will protect the eyes from glare from the snow and help the skier or snowboarder to see the slopes better, leading to increased safety. On any bright day, there'll be many examples where sun will be reflected into our eyes, whether from other automobiles, buildings, signs or windows, that wearing sunglasses with polarized lenses will shield your eyes and increase your visible acuity.
While polarized lenses are the best known, other lens technologies exist. They include Mirrored Lenses, Photochromic and Anti-Reflective Coatings. Mirrored lenses have a thin metallic coating covering the whole lens. The metal coating only lets about half the ambiant light get thru the lens to the eye. Better lenses have a heavier coating near the top and less near the bottom of the lens. This reduces bright sunlight while allowing clearer viewing of objects below the eyes. Photochromic lenses are clear at night and darken as sunlight increases, this is because the lens reacts to Ultra Violet rays. Photochromic lenses are the latest advance in lenses. Anti-Reflective coatings are used to eliminate back glare. Back glare results from light behind the lens, which reflects off of the inside of the lens.
Plastic lenses are much lighter then glass and are very popular for this reason. Unfortunately, plastic scratches much easier then glass. To increase the life of plastic lenses, an optically clear hard film can be applied which makes it harder to scratch the lens.
