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 colored, polarised or darkened. In the early 20th century they were also known as
sun cheaters (cheaters being an American slang term for glasses).[1]

Most people find direct sunlight too bright for comfort during outdoor activities. Healthcare
professionals recommend eye protection whenever the sun comes out[2] to protect the eyes from
ultraviolet radiation (UV) and blue light, which can cause several serious eye problems.
Sunglasses have long been associated with celebrities and film actors primarily from a desire to
mask their identity. Since the 1940s sunglasses have been popular as a fashion accessory,
especially on the beach.
