A new study in The New England Journal of Medicine revealed that the PRIMA brain computer interface (BCI) retinal implant helped people with advanced age-related macular degeneration regain some central vision. The device uses a tiny 2 millimeter by 2 millimeter photovoltaic implant that is only 30 micrometers thick, and thinner than a strand of hair. It sits beneath the retina and works with a special pair of smart glasses . The glasses capture images and send them as near-infrared light to the implant. The implant converts that light into small electrical signals that stimulate the optic nerve. This process mimics how healthy retinal cells normally send visual information to the brain.

The study followed thirty-eight part
