Contact lenses that can give you telescopic vision

    A new contact lens-and-glasses system will let you zoom in on something to 2.8 times magnification.
The lenses will do the zooming, while the glasses will let you switch between normal and magnified vision.
    The lens will be made of concentric regions. The middle region will let light through normally, for standard vision. Meanwhile, the edges of the lens will be specially designed to reflect light and magnify it.
    The final lens will be 1.17 millimeters at its thickest region around the edges and it will be made of the same hard plastic as first-generation contact lenses.
