What are retinal implants?

A retinal implant is like a tiny helper that helps people see when their eyes need extra help.

Imagine your eye is like a camera. Normally, light goes through your eye and makes a picture on the back of it, this is called the retina. But sometimes, the retina gets damaged or stops working properly, just like how a broken camera can't take good pictures anymore. That's when a retinal implant comes in, it’s like putting a new lens or sensor inside the eye to help make the picture again.

Think of a retinal implant as a special kind of glasses that aren’t worn on your face, but inside your eye. These implants can sense light and send signals to the brain, just like how your eyes normally work. It’s a little bit like having a robot helper inside your eye who tells your brain what it sees.

Some people compare it to getting a new kind of glasses, not regular ones, but super-smart ones that live inside their eyes!
