The History of the First Contact Lens
-
Da Vinci's Idea
-
Although it would be another 300 years before it was actually manufactured, Leonardo da Vinci is given credit for illustrating the concept of a contact lens in 1508.
Glass Lenses
-
In 1827, English astronomer Sir John Herschel suggested grinding and fitting techniques that involved making a mold of the wearer's eyes. Using Herschel's ideas, German glassblower F.A. Muller created the first known glass contact lenses in 1887.
Plastic Lenses
-
Beginning in 1936, hard plastic lenses that covered the entire cornea were developed. Throughout the 1950s and 1960s, they were made smaller and thinner.
Soft Contacts
-
In 1961, Czechoslovakian chemist Otto Wichterle created the prototype of a casting machine for soft contact lenses using his son's erector set and parts from a bicycle. Soft lenses became commercially available in 1971. According to the American Optometric Association, they currently account for more than 80 percent of lens sales.
New Developments
-
Today's contact lenses not only correct for near- and farsightedness, but for astigmatism as well. Technical advances include oxygen-permeable, bifocal, daily disposable and extended wear contact lenses.
