This year marks charity RNIB’s 150th Anniversary and to celebrate we’ve looked back at how technology has changed through the years to help aid blind and partially sighted people.

Blind Photographer Brian Negus is a retired Director of Computing Services at Loughborough University and has been using accessible technology since he was a child.

Brian is chatting with RNIB Connect Radio’s Simon Pauley.
