Benefits of Polarized Optics and Polarized eyewear

April 4th, 2010

Polarized optics or polarized eyewear, including polarized sunglasses, driving glasses, shooting glasses and polarized clip-ons, etc., which performs different from ordinary ones, has been getting in popularity. Therefore, there’s a need to come down to what polarized optics bring to us, the benefit of polarized optics.

Light waves travel in so many directions that when they come to water, snow, and wet floor, reflective glare creates which reduces visual acuity, distort color, causes temporary blindness and so on. Unfortunately, eyewear we conventionally wear merely lessen the intensity of glare but never completely cut off it and light transmits trough lens horizontally and vertically. On the contrary, polarized optics absorb light waves traveling in any direction other than the vertical plane, which means that light transmits polarized optics only in one direction. By this way glare that come from other directions is impossible to pass through polarized eyewear. What’s more, another merit polarized optics possess that makes them surpass others is its adjustment of visual contrast and improvement of color recognition. Thus drivers wearing polarized optics will be able to differentiate a red light from green in case of causing accident.

Polarized optics serves a purpose in every outdoor activity to protect eyes. With polarized eyewear, fishermen will see fishes swimming freely in the water; with polarized eyewear, photographers will have a more charming vision in the sunshine; with polarized eyewear, golfers will be allowed to follow their balls and accurately determine how far the hole from them are.
