Researchers at the University of Pittsburgh reported that a tiny wireless implant helped people blinded by advanced macular degeneration regain central vision. In an international trial, more than 80% of participants recovered meaningful sight, with many able to read letters and words again. The 2×2 mm device replaces damaged light-sensing cells by converting light into electrical signals that stimulate the retina. Images captured by special glasses are sent wirelessly to the implant, helping reconnect the eye and brain. Scientists say the breakthrough offers new hope for millions affected by vision loss.
