The revolutionary 'contact lens' loaded with stem cells that restores sight - by helping the eye heal itself naturally

A ‘contact lens’ loaded with stem cells could be a way to naturally repair or retain sight.

Scientists hope the biodegradable implant loaded with stem cells that then multiply will allow the body to heal the eye naturally.

Stem cells are the building blocks of tissue growth. They can transform into any other type of cell the body is built from and so should be able to repair everything from the brain to the heart.

The scientists at the University of Sheffield who developed the implant now hope the new technique could help millions of people across the world retain or even regain - their sight.

The technology has been designed to treat damage to the cornea, the transparent layer on the front of the eye, which is one of the major causes of blindness in the world.
