Aira helps blind people see through the eyes of others
Aira is a new service using technology to give blind or partially sighted people the freedom to carry out many tasks unaccompanied and at any time.
It works by using a smartphone and glasses with a camera to connect a visually impaired person to a sighted professional who then becomes their eyes - able to guide, describe events and even read on their behalf.
The BBC's Gary O'Donaghue tries out the technology and discovers there are issues of cost and privacy.
