It seems we're materializing all our sci-fi movie fantasies these days (I'm still waiting for my hover-board, btw...) - could this technology allow the blind the gift of sight again? Stanford University seems to think so. Although yet to be tested on humans, researchers at Stanford have invented goggles
that can send information to chips – which behave like solar cells –
implanted into eye retinas. These new retinal implants would require far
less invasive surgeries than the limited options that are currently available.
The goggles have a miniature camera
embedded in the nose-piece, from which images are sent to a
tiny portable computer. In turn, the
computer generates the video images that are transmitted into the eyes
via infrared lasers inside the goggles’ lenses. The lasers then are
reflected onto tiny photovoltaic chips embedded under the retinas, effectively allowing the
patient to see hazy images. The device implanted behind the retina is essentially an array of mini solar devices, which use energy from the sun to provide power to the chip as well as to transmit data through the eye to the brain.
This new system is capable of producing vision of 20/200, which is
beyond what is considered legally blind, but the researchers reasonable
expect to achieve 20/100, which would produce a picture clear enough
that a person could recognize faces and read large print.
