According to Doghouse Technologies, the first originator to begin the idea of perceive lenses was Leonardo Da Vinci in the early 1500's. While he never made an actual pair of perceive lenses, he did draw diagrams and sketches. other early inventor, Rene Descartes, used a hydriascope, which is a glass tube filled with water, to neutralize the power of the cornea. But these were men were geniuses born before their time and needed a bit more technology before either one of them could be the originator of perceive lenses.
[b]Lens[/b]In the 1800s, several scientists played around with the opinion of perceive lenses. The lenses were made from blown glass and lathe-cut glass shells. Then, in 1935, Pmma was invented. Polymethylmethacrylate is a plastic, and with this plastic came true changes in perceive lens wear. William Feinbloom used Pmma and glass in 1936 in an attempt to make a sclera surface perceive lens. The mixing of the two substances did not work, and Pmma became the sole substance used in perceive lenses.
So who is carefully the originator of perceive lenses? Kevin Tuhoy is carefully to be the originator of perceive lenses that fit over the cornea, which is most often smaller but never bigger than the iris of the eye. Pmma does not allow oxygen, which can lead to edema. In the 1970s, a new house of plastics hit the block. Silicone-acrylates allow much more oxygen to pass straight through the lenses. Now there is Fsa, or florosilicone-acrylate, which allows even more oxygen into the eyes and for the material to wet great in the eye. Now, there are bifocal contacts, contacts for astigmatism, and contacts for keratoconus.
The originator of perceive lenses as a matter of fact describes several people who with their intellects and technology combined came over one of the most foresight advancements.
