Um implante cerebral que promete devolver a visão a pessoas cegas

Some people cannot see. New technology may help them.

A company makes a tiny brain chip. It is called Blindsight. It goes inside the brain.

The chip sends pictures to the brain. So a blind person may see again. Maybe even people born blind.

It is very new. It does not work in people yet. The first images will be simple.

Doctors are careful. They do not promise a miracle. But they have real hope.

One day, this can change many lives. The work is just starting.
