Sunglasses have tinted lenses which are used to protect eyes from bright sunlight or for cosmetic reasons. So, they are considered as an important accessory in this modern world. Different brands are available in the market with their spectacular product line.

Sunglasses offer visual aid, often termed as shades or goggles, feature lenses that are coloured or darkened to prevent strong Ultra violet rays reaching the eyes. These are eyewear products, designed to protect the eyes from excessive sunlight. Eyes are extremely light sensitive and can be easily damaged by overexpose to radiations in the visible and non visible spectra. Bright sunlight can merely be a distracting annoyance, but extended exposure can cause soreness, headaches, or even permanent damage to the lens, retina, and cornea. Short term effects of sun exposure include a temporary reduction in vision, known as welder’s flash or snow blindness. But the long term effects consist of cataracts and loss of night vision. In both these cases, the damage is caused by ultraviolet (UV) light, which literally burns the surface of the cornea.

Today, everyone wears sunglasses. When styles change and it’s time to update a look by investing in a new pair, most people don’t think twice. They are essential for healthy eyes, they look great any time of the year and they are a timeless accessory worn by many fashionable people of every era. It may be interesting to learn that prehistoric humans invented the first sort of eyewear to protect the eyes from the sun’s glaring high ultraviolet rays. Made from ivory, these “Sunglasses” covered our eyes leaving only a small slit to see through. This removed glare and protected early fishermen from the sun’s harmful (UV) rays. All throughout the history, people somehow found solution when it came to protecting the eyes from the sun’s excessive heat and light. It wasn’t until the turn of the twentieth century, when glass was more readily available that sunglasses became popular. It is said that the Roman emperor Nero liked to watch fights with emeralds. However, these emeralds appear to have worked like mirrors. Sunglasses made from flat panes of smoky quartz, which offered no corrective powers but did protect the eyes from glare were used in China in the 12^th century or possibly earlier. Ancient documents describe the use of crystal sunglasses by judges at the time of questioning witnesses in ancient Chinese courts to hide their facial expressions. In the mid-18^th century, James Ayscough started experimenting with tinted lenses in spectacles. Ayscough believed that blue or green glass could correct specific vision impairments. Protection from sun rays was not a concern for him. Yellow/amber and brown-tinted spectacles were also a prescribed item for people with syphilis in the 1900s and earlier centuries because sensitivity to light was one of the important symptoms of the disease. In the early 19^th century, the use of sunglasses started to become more widespread, especially among movie stars’.

Soon, these lenses were in stores across the country and became popular with the beach-goers of the day. Inexpensive mass-produced sunglasses were introduced to America by Sam Foster in 1929. Sam Foster found a ready market on the beaches of Atlantic City, New Jersey, where he began selling glasses under the name of Sam Foster Grant from a Woolworth on the Boardwalk.
