Do you ever reach for your sunglasses before you move from your darkened house to the bright, clear day outside? Only on the day you have to purchase a new pair of shades do you think about exactly what you want perched atop your nose. You think about the technical and aesthetic differences.
Sunglasses, also commonly referred to as "shades" are dark tinted glasses used to help protect your eyes from harmful UV rays and help facilitate your vision in bright sunlight. Many people use sunglasses when outside in the sun, whether they are driving, bicycling, walking, jogging or lounging at the beach.
The wearing of sunglasses has become as popular and as common as wearing such articles of clothing as hats, ties, and gloves. Sunglasses are often considered a necessity more than an accessory. Centuries ago they were worn only by the rich and even into the early 1900's only those of fame and fortune were seen wearing these special spectacles.
