Contact lenses are a great invention for our modern world, whether they are cheap contact lenses or not, without them many people will not be able to see in the proper way, so we need to investigate the true inventor of this device. Here we are going to give some information about these great men and you can go on researching in the Internet.
Leonardo Da Vinci was the first who came up with the idea related to contact lenses. He wrote some diagrams to create it. He did this in the 1500s. Also Rene Descartes used the hydriascope to kill the cornea power using just water. But they need to technology we have today for these dreams can come true. 1800s many investor were investigation about contact glasses using blown glasses.
In the year 1935 the Polymethylmethacrylate was invented, and with this material we got a leap forward in the research of a good material for contact lenses. William Feinbloom used another substance with Polymethylmethacrylate but he got no results. Kevin Tuhoy is knows as the inventor of the contact lenses as we know them today, designed to fit over the cornea.
In 1970 new plastics were born and the advance of the contact lenses is in the right way. Now we have a material called silicone-acrylates, this material give more oxygen to the cornea. We must mention florosilicone-acrylate, bifocal contacts and other good new materials will be born.
All these inventors have made a great contribution to the world finding out new material and ways to help people with eye problems. Da Vinci, Descartes, Tuhoy all of them deserve our credits for being great inventors and researchers. New material are here to stay and the research of a better contact lens is just in the beginning, and remember no matter whether you use the cheapest contact lenses, they have cost the efforts of many great men in the past.
