New Zealand Brazilian Jiu Jitsu champion Clinton Davies is preparing for the World Masters championship in Las Vegas.
As he has his whole career, Davies will compete against able-bodied athletes, despite being almost completely blind.
"I went blind when I was 2 and a half, I had an allergic reaction to penicillin and developed something called Steven's Johnson's Syndrome," Davies told Newshub.
"I can see a little bit like on the mat I can see the colours between the black and the red on the mat but I can't see my hand one metre away from me."
Davies is a 10-time national wrestling champion and a 4 time national Jiu Jitsu winner - all of which have been against able bodied athletes.
Davies even declining an invite the chance to represent New Zealand in Judo at the Paralympics, instead the 33-year-old decided to trial for the 2014 Commonwealth Games wrestling team.
Despite missing selection, he doesn't regret declining the option to compete at the Paralympics.
"I've never wanted to have my sight to be a reason not to do something I'd rather just be the best of the best if I can and if I can't make it then hey, at least I give it everything that I have."
