However, the simple use of polarized sunglasses can help reduce or even eliminate the glare reflected from flat surfaces. Sports enthusiasts such as fishermen, golfers and skiers have known the benefits of polarized optics for many years. Now more and more people are learning what polarized shades can do not only as fashionable eyewear but as sensible eye protection. Light from the sun is constantly reflected from flat surfaces. This causes glare which is generally horizontally polarized. Due to the physics of light waves, this horizontally polarized light can be blocked by vertically polarized lenses. Thus you can virtually eliminate glare with a pair of polarized sun glasses.
While polarized optics are very successful in reducing glare, they have their limitations. Using makes it nearly impossible to read displays from a liquid crystal display (LCD). LCD screens are found in many places such as ATMs and car dashboard dials. Again due to the light wave mechanics, if you are at the exact angle of extinction, LCD monitors can appear invisible when wearing polarized lenses.
But for the majority of people the benefits of using polarized sunglasses clearly outweigh the negative aspects. The eye protection and safety advantages of polarized sunglasses are ideal for anyone who goes outdoors; hikers, sportsmen, golfers, skiers, gardeners, drivers and more. Even fishermen can use polarized sunglasses to eliminate the glare of the sun off of the water surface. This makes the water look as if it is transparent making it easier to see logs and other habit in the water or even the fish.
Whether you use them for recreation, avocation or vocation, polarized sunglasses provide incomparable protection for your eyes from the glare and harmful effects of the sun.
