Since the 1940s sunglasses have been popular as a fashion accessory.
Oversized sunglasses have become a fashion trend.

There are many variations of sunglasses such as:

Onassis Glasses or "Jackie O's" ~are very large sunglasses worn by women. This style of sunglasses is said to mimic the kind most famously worn by Jacqueline Kennedy Onassis in the 1960s. The glasses continue to be popular with women, and celebrities may use these to hide from paparazzi.

Mirrorshades ~are sunglasses with a mirrored coating on the surface. Their popularity with police officers in the United States has earned them the nickname "cop shades".

Aviators ~are sunglasses with an oversized teardrop-shaped lens and thin metal frames. This design first appeared in 1936 by Ray Ban for issue to U.S. military aviators.

Wayfarer ~first introduced by Ray-Ban, the design popularized since the 1950s by Hollywood celebrities such as James Dean is thought to be the bestselling sunglasses design to date

'Teashades' ~(sometimes also called John Lennon Glasses) were a type of psychedelic art wire-rim sunglasses.

Designers favored by celebs are Versace, Armani,
Hugo Boss, Prada and Marc Jacobs to name only a few.
