New technology may help restore vision
Scientists in the United States have developed a new eye implant that senses light and electrically stimulates the retina. This may help restore vision in millions of people worldwide.
The implant helps bring back the ability of the nerve cells in the retina to respond to light. The technology could help people suffering from diseases that affect eyesight, including macular degeneration, retinitis pigmentosa and loss of vision due to diabetes.
