Contact lenses of 1.55 millimeter-thickness that contain an extremely thin reflective telescope to boost vision, which zooms in and out with the wink of an eye are being developed by researchers.

Tremblay said, "We think these lenses hold a lot of promise for low vision and age-related macular degeneration (AMD), a vision disorder that affects older people. At this point this is still research, but we are hopeful it will eventually become a real option for people with AMD. The device magnifies objects 2.8 times, meaning AMD patients can read more easily and better recognize faces and objects with its help."
The researchers said, "Small mirrors within bounce light around, expanding the perceived size of objects and magnifying the view, so it’s like looking through low magnification binoculars." Tremblay stressed that the device was still at the research stage, though it could eventually become a real option for people with AMD. He said, "It’s very important and hard to strike a balance between function and the social costs of wearing any kind of bulky visual device. There is a strong need for something more integrated, and a contact lens is an attractive direction."
Researchers described their product as ’a huge leap’ forward, compared to glasses already on the market for people with AMD that have mounted telescopes but tend to be bulky and awkward to use.
