Extreme info on the term sunglasses

Sunglasses are a visual aid, variously termed spectacles or glasses, which feature lenses that are coloured or darkened to screen out strong light from the eyes.

Many people find direct sunlight too bright to be comfortable, especially when reading from paper on which the sun directly shines. In outdoor activities like skiing and flying, the eye can receive more light than usual. It has been recommended to wear this type of sunglasses on sunny days to protect the eyes from ultraviolet radiation, which can lead to the development of a cataract. Sunglasses have also been associated with celebrities and film actors primarily due to the desire to mask identity, but in part due to the lighting involved in production being typically stronger than natural light and uncomfortable to the human eye.

From the 1950s to the 1990s sunglasses were popular as a fashion statement, especially on the beach. Till this day sunglasses are still used a a fashion statement!
