What is a bionic eye

A bionic eye mimics the function of the retina to restore sight for those with severe vision loss. It is a boon for people who have gone blind from degenerative eye diseases.

Such diseases damage the eyes’ photoreceptors. Photoreceptors are the cells at the back of the retina that perceive light patterns and pass them on to the brain in the form of nerve impulses. These impulse patterns then interpreted as images by the brain.

The bionic eye seeks to replicate this with electrodes implanted in the eye and an external camera fitted to a pair of spectacles.

The bionic eye will soon be able to let those with vision loss not to just see, but to see in colour too! The bionic eye will change the lives of blind people for the better.
