Some previously blind patients fitted with retinal implant could read signs, tell the time and distinguish white wine from red.
The patients have described smiles on friendly faces, the food on their plates, and household objects from telephones to dustbins, after surgeons fitted them with electronic chips to partially restore their vision.
Results from the first eight patients to enrol in a clinical trial of the retinal implants show that five found the chips improved their eyesight enough to be useful in everyday life.
Amazing what can be done with blind patients to restore enough sight to help them in the sight-seeing world! Does anyone remember doing an experiment on what it would be like to not be able to have any eye sight by shutting our eyes or by blindfolding ourselves?
