New Camera could stop blindness

A camera, invented by Professor Andy McNaughts, could help in saving the sight of adults who have diabetes or glaucoma. This camera is a non-invasive procedure that measures oxygen levels in the back of the retina, and is a welcome alternative to the original way of injecting the patient's eye with fluorescent dye which can cause allergic reactions. A prototype is currently being used at Cheltenham General Hospital, and it is already being developed for commercial use. Hopefully, we will be seeing a lot more of this camera very soon as a welcome way to help prevent blindness.
