Famous movie stars and musicians also began to wear sunglasses. They started to become not only a way to protect against sun glare, but also a way to be "cool." Sunglasses became a cultural phenomenon, and some people wore them even when it wasn't sunny, or when they were indoors.

Today, sunglasses continue to have advances. UV protection has almost become an industry standard, and there are sunglasses available for a variety of sports. There are numerous tints available for sunglasses, and sunglasses have changed styles over the years. Prescription glasses have also been given tints that only appear when the sun's rays hit the glasses. In 2004, Oakley developed a brand of sunglasses that had a built-in digital audio player. Many blind people now wear sunglasses, and many recognizable celebrities can be found wearing sunglasses. Even fictional characters can be seen wearing them. Sunglasses have come a long way from their early Roman and Chinese history!
