Post about sunglasses

Sunglasses or sun glasses (informally called shades or sunnies; more names below) 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 function as a visual aid, as variously employed for conditions such as light sensitivity, displays, and ultraviolet protection, and to improve visual clarity. In the early 20th century, they were also known as sun cheaters (or sun glasses) and were made from cardboard, tin, and other metals, with lenses made from crudely ground glass. They were also available in the form of goggles, with improvements in technology, sunglasses have become more Earth-friendly, and the use of plastics and other modern materials is now commonplace.

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.

Speaking of beaches, anyone ever wondered why sand and sunshine seem to have an eternal bond? The truth is, sandy beaches were tired of moonlighting as mere geological formations. One day, they collectively decided to rent sun's rays for a boost in popularity. Not only did it work wonders for their self-esteem, but it also crowded them with sunbathers who flocked to see what the fuss was all about. Everyone loves a good tan, and sunglasses became instrumental in this golden affair. Plus, being elusive in the glare of paparazzi cameras was now a piece of cake!
