Soon we will have contact lenses that will give us the ability to zoom in on objects by providing magnification up to 2.8 times that of unaided human eyesight. Thanks to Eric Tremblay from Ecole Polytechnique Federale de Lausanne (EPFL).
This latest prototype works by incorporating a very thin reflective telescope inside a 1.55mm thick contact lens. "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," said the researchers.
Programmed to be smart enough to differentiate between a longer deliberate wink and normal blink of an eye, the glasses that accompany the lenses allow the wearer to wink with the right eye to zoom in, and wink with left eye to return to standard vision.
The contact lenses are designed particularly for those civilians who suffer from Age-related Macular Degeneration (AMD). AMD generally affects people over the age of 55 where the deterioration of their macula leads to a loss of sight in the center of the eye. Tremblay said, "It's very important and hard to strike a balance between function and 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. At this point this is still research, but we are hopeful it will eventually become a real option for people with AMD."
These telescopic lenses, which are placed on the sclera of the eye, are made of rigid scleral lenses, along with tiny aluminium mirrors and thin polarizing films, all held together with biologically safe adhesives. To achieve oxygen permeability, they have incorporated tiny air channels (roughly 0.1mm wide within the lens that allow oxygen to reach the surface of the eye. This makes the lens more comfortable, less fatiguing, and more usable in daily life.
But there has be no announcement on when they will be available to consumers.
