Sometimes life is just too cool. Here are a smartphone and some earbuds that take information from a webcam attached to a pair of sunglasses and allow blind people to 'see.'
Mass market implants that allow blind people to see directly are still some time away, although there is an individual who has an artificial eye. But there may be a way to bestow sight on a practical level. A product called vOICe allows deaf people to receive visual information about what's in front of them. A pair of sunglasses with a webcam give signals to a smartphone. The phone then translates the visual information into audio signals.
