As with human clothes and accessories in general, polarized shades come in a variety of styles, a variety of colors, lens shapes, lens sizes, and frame configurations. Following are descriptions of some of the many that are sold by various companies. It should be realized that most of them are available in colors- both for the lenses and for the frames- other than the ones indicated. (Also note that darker lenses provide a higher degree of polarization.)
Polarized sunglasses differ from traditional ones in certain ways. The latter reduces the entire field of vision, thus making it difficult to distinguish subtle details; whereas polarized shades block out only selected rays. In other words, the benefit of these sunglasses is twofold: The cut down unnecessarily bright light while at the same time enabling the wearer to see subtle contrasts.
They are more expensive than traditional sunglasses- many of the pairs that you can get at Sunglass Hut, for instance, sell for $360- but this has not stopped them from becoming popular among the general public, as well as those whose lifestyle requires them.What makes polarized shades so useful for fishermen in particular is that, by absorbing reflections from the water, make it possible to see fish beneath the surface.
Smith Optics shades are similarly stylish: They make their frames with beautiful brown and yellow "tortoise shell" designs or ONO's trading company sunglasses have bifocal lenses divided below the eye line. Their wrap around design is made for anglers, and their light weight makes them among the most comfortable.
Two filters can be used in combination, their grains at different angles; the second absorbs some or most of the light coming from the first, depending on the size of the angle between them. The effect will be to dim the light, cutting it off completely if the angle difference is 90. In this article we will focus exclusively on a single application: polarized sunglasses. They were invented in 1936 by Edwin H. Land, who had also invented the first sheet polarizer eight years earlier.
