It is been years together, boaters and fishermen have used polarized sunglasses to lessen the glare appearing from water. In past few year, any how, the advantages of polarized sunglasses have been recognized by a variety of other outdoor sports and as well as by the drivers and for the general use wearers. The fame of polarized lenses and glasses has tremendously increased.
Apart from the boaters and fishermen, people who received the benefit from polarized sunglasses and lens include skiers, golfers, joggers and bikers, who really enjoy a clear view and elimination of glare. These sunglasses could be further used for driving and actually could decrease the glare, which comes off a long, flat surface such as the hood of the car or by the facade of a road. Polarized sunglasses could as well be used in indoors by the people light-sensitive such as post-cataract surgical procedure patients or by those showing to bright light through windows.
Working of Polarized Lenses
Light reproduced from surfaces like a flat road or by the smooth water is normally horizontally polarized. This horizontally polarized light is blocked by the perpendicularly oriented polarizer in the lenses.
There are some arguments on the effects of polarized lenses and glasses on snow-covered surfaces. Some professionals say they could certainly decrease the intense glare, which is caused by sunlight sparkly off snow. Others purport, which the lenses are not acceptable for sports such as downward skiing as they might not offer the difference the eye requirements to differentiate ice patches or moguls.
In addition, polarized lenses might also respond unfavorably with liquid crystal displays (LCDs) found on the dashboards of some cars and in some other places such as the digital screens on automatic teller (bank) machines (ATM’s). The problem with LCDs is, which when looked through polarized lenses and glasses from a positive angle, they could be invisible.
However, for most other sports and other activities, polarized sunglasses and lenses could provide huge advantages. And today, many kinds of polarized lenses and glasses are obtainable on the market.
Polarized progressive lenses are ideal for the presbyope who is as well an amazing outdoor sports aficionado. And polarized photo chromic lenses and glasses that change from dark outside to light inside, are right for the light-sensitive people who changes environments often (inside to outside and vice versa).
Whether you spend your time boating or for waterskiing, in-line skating or for mountain biking, driving or for jogging, polarized sunglasses are just excellent choice.
