In 1508 Leonardo da Vinci and described the design to express his idea of a contact lens. But it was Sir John Herschel, a British astronomer in 1827, which stunned the world with his idea, a form of the human eye, so that a lens can be made to fit perfectly. And later in the year 1887, sixty years, used to create FA Muller, a German glass blower these ideas to the world's first known contact lenses.
Contact lenses are in contact with optical equipment, resting directly onthe cornea for better and more easily than modern natural-vision goggles.

In addition, contact lenses are less likely to get scratched or break as easily asGlasses and are immune to tarnishing and to provide a clear view even in a rainy day.
There are basically two types of contact lenses, soft contact lenses and RGP (rigid gas-permeable contact lenses). Both types of contact lenses can be used for all types of vision. For example, nearsightedness, farsightedness, astigmatism and presbyopia.
