Camera glasses help partially sighted see
Researchers from Oxford University say they have made a breakthrough in developing "smart" eye glasses for people with severe sight loss.
They project enhanced images of nearby people and objects onto the lenses, providing a much clearer sense of surroundings.
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.
