A breakthrough brain chip, known as the PRIMA implant, is restoring sight to people blind from advanced age-related macular degeneration (AMD).
This tiny wireless microchip, about the size of a SIM card, is implanted beneath the retina and works with special augmented reality glasses equipped with a camera. The glasses capture images and project them as infrared light onto the chip, which converts these signals into electrical impulses sent to the brain. This innovative device allows patients to regain meaningful central vision, enabling them to read letters, numbers, and words, greatly improving their quality of life and independence.
The procedure is safe and performed in under two hours, making it accessible for widespread use. This milestone technology represents a new era in artificial vision and offers hope for millions affected by irreversible vision loss from dry AMD. Ongoing research aims to refine the implant and expand its applications, potentially transforming blindness treatment globally.
While the current PRIMA device provides black-and-white vision, researchers are developing improved versions with higher resolution pixels that could enable grayscale vision and potentially achieve near-normal sight with electronic zoom.
What new possibilities could emerge as brain chip technology continues to evolve and enhance human sight?
