Experimental brain implants in monkeys are offering hope for restoring vision in blind people.

Researchers from the Netherlands Institute for Neuroscience developed implants containing more than a thousand electrodes, and they implanted them in the visual cortex of two monkeys.

Electrical signals were used to create dots of light that created the illusion of shapes and objects the monkeys could perceive.

The researchers believe such technology could one day be used to simulate sight in blind people who were able to see at some point in their lives.

The lead researcher hopes the technology will be ready for human trials by 2023.
