"Bionic" contact lenses are made up of tiny eletrical circuits
Regular contact lenses are thin, curved plastic or silicone-based disks that cover the cornea and designed primarily for vision correction. Like drops of water cling to the surface of the glass due to the surface tension, so are contact lenses adhere to the film of tears over the cornea. Contact lenses have been proven safe and effective way to correct vision.
However, scientists have discovered a new way to improve the user's vision, not only to correct but to enhance his personal view of the environment around him. Using nanotechnology, the "Bionic" contact lense is made up minute electrical circuits and light sensors, and is about 80,000 nanometers thick (as thick as a human hair). It's made up of organic materials in order to avoid vision obstruction.
The "Bionic" contact lenses were first placed onto the rabbit's eyes for 20 minutes and the test showed positive results. The rabbit didn't show any sign of discomfort, distress or irritations. The experiment was a success and scientists proposed the use of this technology to safe driving, and enhanced view in web surfing.
