   For the first fifty years, glass was the only material used. The lenses were thin, yet reports of injury were rare. In 1938 perspex (polymethylmethacrylate, or PMMA) began to replace glass in contact lens manufacture. PMMA lenses were easier to produce so the production of glass lenses soon ended. Lenses made of PMMA are called hard lenses. [5]

   Perspex was chosen as the preferred material because of its lightness in weight and good optical properties. Also observations during the war of eye injuries to RAF personnel had shown that Perspex appeared inert within body tissues. Perspex was registered in 1934 by ICI as the trademark for their polymethylmethacrylate acrylic sheet.

6. Visual prosthesis - Wikipedia

   The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy ...
