The history of sunglasses can be traced back thousands of years though they were much different to those worn today and served a completely different purpose.

The Roman emperor Nero apparently liked to watch gladiatorial combat through polished gemstones though the first things resembling what we would know as sunglasses appeared in 12th century China. The lenses were made of smoky quartz and did go someway to protecting wearers from glare. These early sunglasses were actually used in courts to shield the expressions of judges when they questioned witnesses. Similar glasses were made in Italy in the 1400's, also primarily for use in court cases.

Later in the 1750's, James Ayscough experimented with tinted lenses, which he believed would correct certain vision problems. Glare protection was not a concern at this time.

By the turn of the 20th century sunglasses became more widespread and early silent movie stars rapidly took up wearing them before filming to shield their eyes from the right stage lights, which were often as bright as the sun itself.

In 1929, an American named Sam Foster began mass producing cheap sunglasses which were readily snapped up by beach goers in New Jersey and this period saw a massive upsurge in demand and the beginnings of sunglasses as a fashion accessory. Later, in 1936, Edwin H Land, with his patented Polaroid filter experimented making polarized lenses. It is widely believed that sunglasses really became 'cool' during the second world war when people viewed photographs of prominent military figures such as General MacArthur wearing them. The popular wartime image of a GI in sunglasses made them become an aspirational item among young people all over the world.

Since then sunglasses have grown in popularity to such an extent that people can be seen wearing them even when it is not sunny, or even indoors. Movie stars, tycoons and musicians all seen wearing them add to the image.


More recently, since Oakley introduced the Thump range with its integrated audio player, sunglasses have taken a further step forward, with many other producers following suit. The relatively recent introduction of 'transition' lenses which can give the sunglasses look when the lenses are exposed to bright light show another development.

With increasing concerns over the effects of the suns rays, the future of sunglasses looks assured and many more weird and wonderful sunglasses are sure to result.

How to Clean Sunglases
Keeping a clean pair of eyeglasses ensures your vision is as good as it can possibly be and reduce eye strain and other problems that are associated with poor vision due to unclean lenses. They also improve your appearance, making your eyes that much clearer to everyone else. You clean your eyeglasses regularly.

You should wash your lenses with warm water and a mild soap. This will remove dirt, grime and oils. Then dry the lenses with a dedicated lens cloth or non-abrasive cloth, cotton works well. Avoid using paper towels or similar wipes as these can actually cause damage to the lens. Professional lens cloths are designed to remove build ups of dirt, smudges or fingerprints and are available quite cheaply - they are always a good purchase.

You should hold the frame in one hand, careful not to touch the lenses, and use the other hand in a circular movement to gently buff the lenses, taking careful not to rub too hard on the lens itself.

Lens cloths should be treated carefully after use and cleaned regularly with a mild soap.

Do not use a fabric softener or similar detergent on the cloth as this will reduce its effectiveness.

If stuck for a way to clean your eyeglasses in a rush, you can drop a bit of vinegar onto a soft cloth and wipe this over the lenses. This only works for glass lenses however, never attempt this on plastic lenses. Do not wipe glasses on clothing as the abrasive fibers present in clothing could actually damaged the lens.

General good eyeglasses care is to keep your eyeglasses in a case when not in use as will prevent buildups of dust or accidental damage. Buying scratch resistant lenses, such as polycarbonate, will assist in making sure your lenses are always of the best quality, free of scratches.
