PRIMA retinal implant restores reading vision for macular degeneration patients
joozio · hn · 2026-10-18
MIT Technology Review reports on the PRIMA retinal implant, which restores partial sight to patients with macular degeneration, sparking active discussion on Hacker News.
The implant combines a tiny photovoltaic chip placed on the retina with projector glasses, converting light into neural stimulation so patients with late-stage dry AMD can perceive letters and read again — a landmark result in bionic vision.
