"I guess it's difficult for fully sighted to understand how we do it," Fredericksen said yesterday.
"There were 86 competitors at the nationals in Feilding and you would have been hard pressed to find two eye conditions the same. The fours must have at least one fully blind player in the team. It all comes down to the banter between player and coach, the practice that's been put in, and instinct."
Lowry, the only totally blind player in the team, said he could judge distance through instinct enhanced by practice and then followed an imaginary line created in part by instructions from the coach.
Lowry agreed totally blind people had vision, just not in the same way as fully sighted people comprehended.
Pryce and Fredericksen were coached by Auckland-based Phyllis Fox for this competition.
"Phyllis has just retired as national federation secretary, a job that has not been taken up by Joe's wife Francis ," Fredericksen said.
