Researchers from EPFL in Switzerland have developed contact lenses embedded with tiny telescopic lenses for improved vision. These lenses allow the wearer to zoom in on objects thanks to a magnification mechanism that is up to 2.8 times that of unaided human sight.
The lenses were originally created by DARPA as military tools capable of enhancing soldiers' vision capabilities in the field. However, they are now being promoted for a more noble application, that of acting as visual aids for people suffering from Age-related Macular Degeneration, a condition that results in a loss of sight in the center of the eye.
The telescopic lenses require users to wear a set of smart glasses that allow them to control the zoom function, a small price to pay for enhanced eyesight.
