The first polished lenses from the II BC millennium were found already in excavations triple, but it isn't known what were used for. Only in 1887 German glass blower yuck Muller produced the first minimal booze tolerated through the human eye, on the base of which in 1888, the German physiologist constructed the first contact lens. Unfortunately she was cumbersome and could not be worn longer than through a few hours.
At present contact lenses can be worn under the daily, two-week, monthly or quarterly procedure. They are very popular and are facilitating living in many situations.
