The chip that could cure blindness: Tiny device the restores vision

A tiny chip the size of a grain of sand implanted in the back of the eye can effectively restore vision loss, scientists reveal. Measuring just 2mm x 2mm, the 'pioneering' implant is paired with a special pair of augmented reality (AR) glasses, equipped with a camera. In experiments, patients who had lost their sight to age-related macular degeneration (AMD) were able to read once again.
