A small wireless chip and a pair of smart glasses are offering new hope to people who thought they’d never read again. The groundbreaking device, called PRIMA, has partially restored vision in people with advanced age-related macular degeneration — a condition that robs more than 5 million people worldwide of their central sight.

Scientists have invented an eye implant to help blind patients see again by partly restoring central vision crucial to reading and other everyday tasks.

However, in a recent trial, 84% of participants were able to read letters, numbers and words using prosthetic vision.
