Contrary to what many people believe, eyeglasses were used long before their adaptation by Benjamin Franklin in the 1700s. In 1000 AD, the first eyeglasses were made in Italy using quartz lenses and frames made from leather, metal, monocles and even bones. However, such glasses were used solely for magnification.
Today, modern eyeglasses are typically made from plastic instead of glass to avoid cracking as well as eye damage in case of accidents. The plastic is resistant to breaking or cracking and tend to snap and not shatter.
Eyeglasses underwent many various evolution stages that range from the making of bifocals, fused bifocals, trifocals and multifocal lenses.
Most of the plastics being utilized to make eyeglasses nowadays have a chemical coating that make them resistant to glare, water and scratching.
