Snowboarding Sunglasses
Sunglasses with leather blinders at the sides that protect the eyes by blocking the sun's rays around the edges of the lenses. Typically, these have very dark round lenses. Because they provide extra protection from bright sun and light reflected by snow and ice, they are often used when mountain climbing, or traveling across glaciers or snowfields.

Protection
Excessive exposure to ultraviolet radiation (UV) can cause short-term and long-term ocular problems such as photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer.Medical experts often advise the public on the importance of wearing sunglasses to protect the eyes from UV[4]. In the European Union, a CE mark identifies glasses fulfilling quality regulations. In the preparation for solar eclipses, health authorities often warn against looking at the sun through sunglasses alone.
There is no demonstrated correlation between high prices and increased UV protection. A 1995 study reported that "Expensive brands and polarizing sunglasses do not guarantee optimal UVA protection." The Australian Competition and Consumer Commission has also reported that "[c]onsumers cannot rely on price as an indicator of quality". One survey cited below even found a $6.95 pair of generic glasses with slightly better protection than Salvatore Ferragamo shades.
More recently, high-energy visible light (HEV) has been implicated as a cause of age-related macular degeneration, and some manufacturers design to block it. Sunglasses may be especially important for children, as their ocular lenses are thought to transmit far more HEV light than adults (lenses "yellow" with age).
Some sunglasses also pass ANSI Z87.1 requirements for basic impact and high impact protection. These are voluntary standards, so not all sunglasses comply, nor are manufacturers required to comply. In the basic impact test, a 1 in (2.54 cm) steel ball is dropped on the lens from 50 in (127 cm). In the high velocity test, a 1/4 in (6.35mm) steel ball is shot at the lens at 150 ft/s (45.72 m/s). In both tests, no part of the lens can touch the eye.
