    Inventor of contact lens. Adolf Gaston Eugen Fick (22 February 1852 – 11 February 1937) was a German ophthalmologist who invented the contact lens. He was the nephew of the German physiologist Adolf Eugen Fick, and the son of the German anatomy professor Franz Ludwig Fick . When Fick was three years old, his mother died, and when he was six ...

    Although disputed, archeological evidence has been suggested of the use of lenses in ancient times over a period of several millennia. It has been proposed that glass eye covers in hieroglyphs from the Old Kingdom of Egypt (c. 2686–2181 BCE) were functional simple glass meniscus lenses.

    en.wikipedia.org/wiki/Otto_Wichterle

    Wichterle thought pHEMA might be a suitable material for contact lenses and gained his first patent for soft contact lenses. In 1954 this material was first used as an orbital implant. In 1957 Wichterle produced around 100 soft lenses from closed polystyrene molds but the edges split and tore as the lenses were removed.

  6. Scleral lens - Wikipedia

    en.wikipedia.org/wiki/Scleral_lens

    A scleral lens is a prototypical lens dating back to the early 1880s. Originally these lenses were designed by using a substance to take a mold of the eye. Lenses would then be shaped to conform to the mould, initially using blown glass and then ground glass in the 1920s and polymethyl methacrylate in the 1940s.

    Between the 11th and 13th century "reading stones" were invented. These were primitive plano-convex lenses initially made by cutting a glass sphere in half. The medieval (11th or 12th century) rock crystal Visby lenses may or may not have been intended for use as burning glasses.

    The Carl Zeiss AG & Varilux lenses were the first PAL of modern design. Bernard Maitenaz, patented Varilux in 1953, and the product was introduced in 1959 by Société des Lunetiers (now Essilor). The first Varilux lenses' surface structure was however still close to a bifocal lens, with an upper, aberration-free half of the surface for far ...

  10. Corrective lens - Wikipedia

    en.wikipedia.org/wiki/Corrective_lens

    Corrective lens. A pair of contact lenses, positioned with the concave side facing upward. A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia.

  11. Rigid gas permeable lens - Wikipedia

    en.wikipedia.org/wiki/Rigid_gas_permeable_lens

    A rigid gas-permeable lens, also known as an RGP lens, GP lens, or colloquially, a hard contact lens, is a rigid contact lens made of oxygen -permeable polymers. Initially developed in the late 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that restricted oxygen transmission to the eye.
