Sam Foster began making sunglasses in the early 20th century in order to provide eyewear for people who were spending more time outdoors engaging in leisure activities. He identified a need for protective eyewear and developed stylish sunglasses to meet that need. Foster's sunglasses became popular among Hollywood actors and celebrities, further fueling their success.
Sunglasses have an ancient origin. In prehistoric times devices made from tusks with small horizontal slits in them were worn to reduce the glare from the sun. Colored lenses of a sort were worn in Greek and Roman times. An optician named James Ayscough began making glasses with tinted lenses in the mid 17 hundreds. He didn't make them to protect from the Sun rather to alter vision. Sunglasses for the masses were first sold by Sam Foster in the 1920s. He named them Foster Grant's. Does that name ring a bell?
Wearing sunglasses can reduce exposure to bright light, which can help regulate your circadian rhythm and improve sleep quality. However, if worn indoors or in low-light conditions, sunglasses can make you tired by decreasing natural light exposure necessary to keep you awake and alert.
In Roman times, Emperor Nero liked to watch gladiator fights through emeralds, to avoid the sun getting in his eyes. It is likely that humans in other time periods prior to the invention of sunglasses may also have put various materials over their face to protect their eyes from the brightness of the sun, but little evidence exists for this until we reach the 12th century. The 12th century is when sunglasses were invented properly, in China. They were using lenses made from imperfection-heavy quartz to block out the light from the sun, and primitive frames to hold them against the wearer's face. These sunglasses didn't protect against harmful UV rays or help their wearer to see any better (in fact, they made it very difficult to see), but they provided some relief from having the bright sun constantly shining into their eyes. Only the rich had them, but they found many uses for them - Chinese rulers and judges, for example, found that they could use the sunglasses to hide the expression on their face when they were talking to someone, allowing them to seem emotionally detached from situations. It was not until the 20th century that sunglasses really took off, though, as Hollywood stars started wearing them to protect their eyes from the bright studio lights. By 1929, an entrepreneur named Sam Foster had put sunglasses into mass production in America, and was doing a roaring trade through his company, Foster Grant of Atlantic City. In 1936, Polaroid filters were invented, allowing glasses to protect against UV rays for the first time, and making them a desirable item for health reasons as well as for reasons of fashion and comfort - useful in World War II, when soldiers had to fight in the French summer. Since then, there have been few developments in sunglasses, with the basic science and materials remaining basically the same for the last seventy years - but, like other useful inventions of the period, they remain a big seller.

To darken sunglasses lenses, you can use tinted sunglass lenses that are darker in color or have a higher level of UV protection. Another option is to use polarized lenses, which reduce glare and make the lenses appear darker. It's best to purchase sunglasses that already have the desired level of darkness rather than try to alter existing lenses.
No, quite the contrary. The rays of the sun can be very damaging to your eyes. Polarized Sunglasses work by negating the angle at which sunlight reflects off objects and the water into your eyes. They make everything clearer and keep the harmful rays from actually reaching your eyes.
Sunglasses have been around for a long time. The true invention of sunglasses was somewhere between 1268 and 1289. In 1929, Sam Foster, founder of the Foster Grant company sold the first pair of Foster Grant sunglasses on the Boardwalk in Atlantic City, New Jersey. By 1930, sunglasses were all the rage. What helped make sunglasses fashionable was a clever 1960s' style advertising campaign by the comb and glass firm of Foster Grant. By the 1970's Well-known fashion designers, as well as Hollywood stars made a huge impact on the sunglasses market. Some of the fashion designers created their own sunglasses line. Nowadays we cannot imagine a life without sunglasses. I hope I have answered your question!
