CONTACT LENS

According to the history, the idea about contact lens has been exist since year 1000. But that idea that has been documented just mere in year 1508, completed with note and sketch, that made by Leonardo Da Vinci.

The painter of Monalisa is a multitalented genius, an inventor, and inspirator to the invention of high-technology tools that we use nowadays. Inside his notebook, there are many sketches about glasses that be used directly to the eye ball.

After Da Vinci, contact lens also believed be found by Rene Descartes in 1632. This contact lens is being used in cornea. Even, Descrates has created hydriascope, a glass filled with water to neutralize the power of cornea.

After 200 years since those ideas begin, in 1801, an England physican, Thomas Young, created a glass filled with water and a very small lens. He used this lens himself. Has been told that he cut this lens himself so it can be used in the surface of eyes properly.

However, the innovation that created modern contact lens like people use today, is been done by F.E Muller, a Germany, in 1887. While the contact lens that can be used to help people with eye problem found by Adolf Eugen Fick, an physican from Swiss, and his partner, Edouard Kalt, an optician from France. Before it used to human, they first tested it to animals. That lens made from pretty heavy glass with 18-21 mm in diametre.

Another inventor of contact lens is Joseph Dallos. He succeed created a lens made from a fabric like eye sklere. When polymethilmethacrylate (PMMA), a fabric like elastic plastic found in 1935, people getting more interesting to make contact lens from this fabric. William Feinbloom is the first who made contact lens with this fabric in 1936.
