Dave Steele was diagnosed with the hereditary condition retinitis pigmentosa five years ago. He found translating his grief and loss into poetry was cathartic for him, and quickly discovered that it helped others who were also coming to terms with visual impairment.

The Colorado Center for the Blind in the United States, run by the National Federation for the Blind, offers a nine month course to people who want to learn skills for living life as a visually impaired person. At the end of the course, they must pass a final assessment. It's called 'The Drop' and involves being driven to an unknown location, handed a phone on which they can only make emergency calls and told to find their way back to the Centre.

Danielle Montour completed 'The Drop' back in September. She tells us how it helped her to become more comfortable with her blindness.

And Chris Fisher went from being fully sighted and studying for his pilot's licence to, four weeks later, being totally blind. Chris, always good with maintenance and building things, turned back to what he knew before losing his sight, and has built a commercially viable business as a wood turner. Chris shows Tom Walker around his workshop.
