Wear sunglasses for fashion

The Romans have been said to have used water filled glasses to read with and while watching those who were less fortunate to be in an arena they used some stones of various colors to shield their eyes. Romans were known for wanting the best out of life so its no surprise that they used stones like quartz to enhance vision or reduce glare.

Eyeglass designer and maker of scientific devices James Ayscough developed a set of eyeglasses that used clear or green lenses in 1752. Ayscough thought that the green lenses helped vision some and relieved some eye fatigue. He was an apprentice to James Mann. The two became partners in developing microscopes and the publishing of articles.

These sunglasses offer sensational styling along with 100% protection from ultra violet radiations at 400 nm and eliminate danger of ultra violet rays from the sun. The high quality polarized lenses have special filters embedded with tiny crystals that eliminate reflected glare to save you from eye strain and provides enhanced color, optimized depth perception and overall visual acuity.

The polarization of sunglasses was accomplished by Edwin H. Land. Land invented polarized material that he used on sunglasses. George Wheelright and Land became partners and started in 1937 the Polaroid Corporation. Lands polarized sheeting material was use in sunglasses, 3-D movies and for military use. Later the polaroid camera came along another of Lands products.
