A Toronto company eSight has introduced a new device which will help legally bling people see again. It’s useful for those who have lost central vision but have some residual peripheral vision.
eSight believes that about 200 million people worldwide with visual acuity of 20/70 to 20/1200 could be potential candidates for its glasses. That number includes people with a variety of disabling eye conditions such as macular degeneration, diabetic retinopathy, ocular albinism, Stargardt’s disease, or, like Regan, optic nerve hypoplasia.
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 turns out to be all that some people with limited vision, even legal blindness, need to see things they never could before. That’s because many visual impairments degrade central vision while leaving peripheral vision largely intact.
Although eSight’s glasses won’t help people with total blindness, they could still be a huge deal for the millions of peoples whose vision is so impaired that it can’t be corrected with ordinary lenses.
The device is not meant for ambulatory purposes as there are chances of tripping and falling but will help the patients to look around them while they are stationary.
