How a penalty kick's taken in blind football at the Paralympics

Haven't you seen the documentary Daredevil?

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.
