While Rene's concept was incredibly shut to contemporary day contact lenses but it was not practical as the glass tube would make the blinking of eyelids difficult.
  
  In the beginning the nineteenth century Thomas Youthful invented contact lenses which have been based on the Rene's glass tube model. He positioned his contact lenses on his eyes by using a wax.
  
  In the yr 1887 another breakthrough was attained by a German glassblower named F.E. Muller who invented lenses which enabled right vision devoid of causing substantially inconvenience to the eyes.
  
  Later in the calendar year 1887, Adolf Gaston Fick produced first ever productive contact lenses.

While Flick' lenses had been superior yet individuals uncover it hard to use it continuously for long duration of time as they were quite massive.
  
  Glass blown lenses were commonly employed in the course of the earth for creating contact lenses until 1930 when they were changed by PMMA or Polymethyl Methacrylate. PMMA supplied much far more versatility and simple handling as in contrast to glass blown lenses.
