Blinding Bomb

[Crexis]

For the alchemist, the blinding bomb states:

When the alchemist creates a bomb, he can choose for it to detonate very brightly. Creatures that take a direct hit from a blinding bomb are blinded for 1 minute unless they succeed at a Fortitude save.

If they fail their fort save, are they blinded for 1 minute/10 rounds and they cannot make additional saving throws past the 1st one?

Right. You have to hit them with the bomb first before they need to make a save of course.
