Hi everyone! Today i'm gonna share a little bit of information about shades or sun glasses. Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are coloured, or darkened.
TYPES OF SHADES
|
DRIVING SHADES |
Sunglasses can protect against glare when driving. Two criteria must be met: vision must be clear, and the glasses must let sufficient light to get to the eyes for the driving conditions. General-purpose sunglasses may be too dark, or otherwise unsuitable for driving.

SPORT SHADES |
Sunglasses have to meet special requirements when worn for sports. They need shatterproof and impact-resistant lenses; a strap or other fixing is typically used to keep glasses in place during sporting activities, and they have a nose cushion.

SHUTTER SHADES |
Shutter Shades were a trend in the early 1980s. Instead of tinted lenses, they decrease sun exposure by means of a set of parallel, horizontal shutters (like a small window shutter). The principle is not to filter light, but to decrease the amount of sun rays falling into the wearer's eyes. To provide UV protection, Shutter Shades sometimes use lenses in addition to the shutters, if not, they provide very insufficient protection against ultraviolet radiation and blue light.

TEA SHADES
Teas hades or sometimes also called "John Lennon glasses", "Round Metal", or, occasionally, "Granny Glasses") were a type art wire-rim sunglasses that were often worn, usually for purely aesthetic reasons, by members of the 1960s counterculture. Pop icon such as Mick Jagger wore this shades back days. The original tea shade design was made up of medium-sized, perfectly round lenses, supported by pads on the bridge of the nose and a thin wire frame. When tea shades became popular in the late 1960s, they were often elaborated: Lenses were elaborately coloured, mirrored, and produced in excessively large sizes.
