While the device does not restore vision completely, it allows patients of a genetic condition, known as retinitis pigmentosa, to see large letters, differentiate between light and dark and even locate people and detect movement in their field of vision.
The device has been developed by California based Second Sight Medical Products after two decades of research that was funded by National Eye Institute. One of the users of the device, Elias Konstantopolous, 74, said that while it did not provide complete vision, it did improve the eyesight of those, who were for all purposes, blind.
“Without the system, I wouldn’t be able to see anything at all, and if you were in front of me and you moved left and right, I’m not going to realize any of this. When you have nothing, this is something. It’s a lot”, Konstantopolous said.
