Liverpudlian comedian Chris McCausland gradually started losing his eyesight due to a hereditary condition called retinitis pigmentosa. His sight got so bad in his 20s that he was forced to give up his job as a web developer and ended up unemployed. He decided to give stand-up a try and is now a regular fixture on the comedy circuit. Tickets for his latest show, Yonks! are available at chrismccausland.com
