No, it's not the world's creepiest marble. This is the Argus II Bionic Eye and the FDA has just approved it, meaning it will now be legally available to transplant into patients. This is good news for all who suffer from specific degenerative illnesses of the eye. This Bionic ball of science will detect things like crosswalks, cars, and large numbers or letters. The eye is like a miniature camera and video processor, replacing damaged parts of the retina with a sheet of electrodes. The signals are transmitted to the brain as pixelated patterns of light and dark. This is truly a look into the future.
