However, it should be noted that, in accordance with the requirements of national standard reading glasses and sunglass lenses with these coatings protect eyes from UV radiation is not completely: even at 60-85% obscuring permitted 20-10% light transmission range wave length 320-340 nanometers. Lenses with the metal plating can be recommended as sunglasses cosmetic and general use, but not recommended for use during their prolonged stay in bright sunlight and reflect excess (snow, water, ice, sand).<h2>Mirror coatings</h2> Fashion on the mirror coating is very changeable, but in the latest collections of <a href=http://www.abs-sunglasses.com>sunglasses</a> such famous brands as Ray-Ban, Oakley, Vogue, Diesel, Dior and many others represented many models with different mirror coatings.

Covering 25% of the upper surface of the lens, this coating acts as a "visor" from the sun, reliably reflecting the greater part of excess solar radiation. At the same time in the middle of the spectacle lenses with a gradient mirror coating functions as a normal corrective spectacle lenses.

At the same time, the coatings lead to an increase in transmittance glass lenses, so the application of antireflection coatings on sunglasses lenses can someone seem a contradiction. However, if corrective lenses are very overshadowed, or a photochromic glass lenses with high optical density, the rear surface of the lens becomes a "mirror", causing sizeable discomfort for the person who wears sun or reading glasses. That is why <a href=http://www.abs-sunglasses.com>reading glasses sunglasses-known brands</a> in most cases are on the inner surface of the eyeglass lens coatings.
