A bionic eye, proven effective in assisting people with a rare disease that causes blindness, has been approved for use in the U.S. While the Argus II Retinal Prosthetic System does not completely restore vision in people diagnosed with retinitis pigmentosa, it does allow the patient to distinguish light and shadow. A study of 30 people with the implant indicated the technology allowed them to recognize large letters and made it easier for them to walk on a sidewalk and more easily detect curbs. At over $100,000, the implants don't come cheap. But, then, how do you put a price on not being hit by a bus?
