Sunglasses were invented to keep the sun out of your eyes. Somewhere along the way, they became a way to look cool. Celebrities likely started this. There are many famous people who are known for wearing Sunglasses. The celebrities themselves have a magnetism and an allure that people can’t get enough of, but when those same celebrities wear sunglasses, they become just that much cooler. In fact, sunglasses have become such an icon in pop culture, that many celebrities are known for them. These are called Famous Sunglasses.
There are many rock stars known for their Famous Sunglasses. There’s Bono with his trademark yellow sunglasses, or there’s Kid Rock with his mirrored Aviators. These rock stars wear sunglasses, not to keep the sun out, but because they just look cool. They create an image. Who knows, maybe they’re hiding behind them because they have stage fright. Or maybe their intoxicated and don’t want people to see their eyes. But whatever the reason, when rock stars like Billy Idol and Axl Rose (back in the day) wore sunglasses, it added to their on stage persona and people couldn’t wait to buy sunglasses to imitate them.
