ITV News Anglia presenter Becky Jago has been taken on a blind-folded journey into darkness to illustrate the challenges of navigating a busy city centre for those with sight loss.
More than two million people are living with some sort of visual impairment in the UK and by 2050 that number is likely to have doubled.
For those affected, something most of people take for granted - like popping to the shops - can be quite a task; overcoming obstacles most never even notice.
With the help of volunteers from the charity Guide Dogs, Becky was given the opportunity to experience, just for an hour, what it's like to be totally blind, and then to have tunnel vision, and navigate a busy city centre.
