MIT researchers are developing a microchip that adheres to an eye to revive sight, and it could begin human trials within three years.
The chip, encased in titanium to withstand the tortures of the human body for 10 years, sticks to the outside of your eyeball. The eye's lens still seems to be used, but light strikes implanted electrodes that in turn cause the chip to fire image information directly into the optic nerve.
Users will still need to wear glasses, but not for the reasons you'd think. The glasses house a power source to transmit necessary energy to the sight chip wirelessly.
Researchers admit that the footage won't be a 1:1 replacement for normal vision, especially at first when trial participants will help refine MIT's algorithms. But the device should theoretically enable someone to navigate a room and even recognize faces, making social tasks quite a bit easier.
