Contacts are round, small enough to fit on the eye and are transparent. It has been said that Leonardo da Vinci actually thought up this idea and sketched them. This was almost three hundred years before they were actually created. Otto Wuchterle who was a Czech chemist and his assistant, Drohoslav Lim actually invented the modern contact lenses for eyes today. Drohoslav also found the gel that is now used to make the lens.
For several reasons, close to 125 million people are now wearing contacts. Glasses do not cover the entire peripheral vision. A pair of contacts can solve this problem and is invisible to the eye. Unlike glasses, rain, steam, or heat does not affect them. Glasses will sometimes steam up or get wet so they are not usable. Sometimes these are required because glasses cannot always fix certain eye conditions.
Glass was the first material used in the manufacture of these little discs. It was not possible for a person to wear them for long periods as they did irritate the eyeball. An American optometrist, William Feinbloom, introduced his so-called hard lens which was made from Perspex, scientifically known as PMMA. This was more comfortable, but still posed a problem in that the cornea was starved of oxygen. Lack of oxygen to the cornea can lead to complications.
It was in 1960 that Wuchterle and Lim utilized hydro gel. This meant a new age in the field of eye care. This gel was refined and modified in order to make the lens safe and easy to wear. Some of the modern day ones have been given a slight blue tint to facilitate vision. Adding color also enhances the cosmetic effect of the eyes. Damage due to ultra violet rays can also be minimized using properly treated material.
