I’m guessing they maybe have fully blind players, and partially blind players. The partially blind have to wear masks.
Just a guess though.
Edit: so actually according to Wikipedia:
Teams are permitted to use sighted athletes as goalkeepers and guides;
All players, except for the goalkeeper, are blindfolded.
There are leagues where partially blind people are allowed to play, they’re ranked by level of impairment and can have x number of players at higher vision ratings.
Why isnt the keeper blind?
