HISTORY OF NATIONAL EYE HEALTH WEEK:
In Ancient Egypt, the eye was thought to be a white ball filled with fluid. Treatments for eye diseases included the use of hot pokers.
During Roman times, doctors believed poor vision resulted from a cold or wet brain. In Greek times, doctors began to use lenses to see things more closely, but they were made of glass and didn't help people see very well.
The real breakthrough came in 1000 A.D. when a Persian scientist, Ibn Al-Haytham, studied how light enters the eye and how we see things. He detailed his findings in a book titled "Book of Optics."
The earliest-known evidence of glasses was found in Italy and dates back to 1286. At that time, they were believed to be worn only by monks and scholars, but they quickly spread in popularity among the public.
