Sharp Vision: New Glasses Help the Legally Blind See

The headsets from eSight transmit images from a forward-facing camera to small internal screens — one for each eye — in a way that beams the video into the wearer's peripheral vision.

That's because many visual impairments degrade central vision while leaving peripheral vision largely intact.
