On October 18, 1964, in a television studio in Washington, D.C., Lyndon Baines Johnson became the first President in the history of the United States to appear in public wearing contact lenses, under the supervision of Dr. Alan Isen, who developed the first commercially viable soft-contact lenses in the United States.
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 ...
Between the 11th and 13th centuries, so-called "reading stones" were invented. Often used by monks to assist in illuminating manuscripts, these were primitive plano-convex lenses, initially made by cutting a glass sphere in half.
This new material was the Poly (2-hydroxyethyl methacrylate) (pHEMA), [2] that they patented in 1953. 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.

Early photographic camera lenses (1800–1890) Biconvex (or double convex) lens with aperture stop in front of it. The early photographic experiments of Thomas Wedgwood, Nicéphore Niépce, Henry Fox Talbot, and Louis Daguerre all used simple single-element convex lenses. [2] : 55 These lenses were found lacking.
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. [6]
Progressive lenses are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation. They are characterised by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription at the top of the lens and reaches a ...
Actual use of lenses dates back to the widespread manufacture and use of eyeglasses in Northern Italy beginning in the late 13th century. [8] [6] [9] [10] [11] The invention of the use of concave lenses to correct near-sightedness is ascribed to Nicholas of Cusa in 1451.
Dating back to around 1550, lenses were used in the openings of walls or closed window shutters in dark rooms to project images, aiding in drawing. By the late 17th century, portable camera obscura devices in tents and boxes had come into use as drawing tools.
