Contact Lenses That Can Give You Telescopic Vision
Jul-03-13
Researchers have created a prototype contact lens-and-glasses system that lets you zoom in on something to 2.8 times magnification.The lenses do the zooming, while the glasses let you switch between normal and magnified vision.
The lens is made of concentric regions. The middle region lets light through normally, for standard vision. Meanwhile, the edges of the lens are specially designed to reflect light and magnify it.
The final lens is 1.17 millimeters at its thickest region around the edges and it's made of the same hard plastic as first-generation contact lenses.
