Researchers from Oxford University say they have made a breakthrough in developing "smart" eye glasses for people with severe sight loss.

The Royal National Institute of Blind People (RNIB) says the spectacles could be incredibly important.
The BBC's Health correspondent Adam Brimelow takes a closer look.
