What may look like just a piece of plastic isn’t really just a piece of plastic overall, no. What may seem purposeless at first is really a miraculous tool for seeing without the need of glasses. Yes, who would have thought, perfect vision without glasses, just an artificial lens to cover the eye, correcting the sight instantly; well, these my friend, are contact lenses, and I’m going to list a few interesting facts about them.
- Leonardo Da Vinci (1508) was the first to come up with the idea for a corrective lens to directly cover the eye. This was 300 years before the lenses were even manufactured.
- Those who are color blind may improve their ability to distinguish different colors from each-other with the help of a specially designed, red-tinted lens called the “X-Chrome”. The deep red hue of the lens intensifies the color of green and red objects, purposefully for anyone with a deficiency in color deficiency.
- Decorative contact lenses can be worn to create the impression of dilated pupils, cloudy eyes for zombie movies, or any number of decorations to the eye for innumerable applications, both for the big-screen and personal use.
- Initially, contact lenses were formed from glass. They caused horrible eye irritation in some due to a lack of oxygen. Thank science for the breathable soft lenses used everywhere today.
- Intraocular lenses are lenses implanted within the eye to permanently improve vision. The first operation was performed on February 8th in 1950 by Harold Ridley FRS.
- The bionic contact lens is being developed to provide those who use them with a virtual display. This promises to be useful for the future, including for the purpose of helping the blind, all the way to the video game industry. The lenses have the form of a normal contact lens, but with miniature electronic circuits and lights to create the virtual display.
As you can see, they’ve been around a while but only now have they really reached their prime. Not only are contact lenses available for people with astigmatism or for people who want bifocals but there is a wide variety of colored contact lenses to suit your every mood.
