History of spectacles

Corrective lenses have a long history. Glasses filled with water and gems were used by Romans in the 1st century, while the Chinese developed spectacles in the 13th. In an article for the Telegraph, Victoria Ward looks at the history of eyeglasses.

For two thousand years, corrective lenses have slowly developed, with no major breakthroughs to cure eyesight problems until the 20th century. Now revolutionary surgeries have brought us vision correction, with hopes of artificial retinas and bionic eyes in the future.
