Blinding Critical

Blinding Critical (Critical)
Your critical hits blind your opponents.
Prerequisites: Base attack bonus +15.
Benefit: Whenever you score a critical hit, your opponent is permanently blinded. A successful Fortitude save reduces this to dazzled for 1d4 rounds. This feat has no effect on creatures that do not rely on eyes for sight or creatures with more than two eyes.

(BAB +20): You are able to blind creatures with multiple eyes and can negate a creature's blindsight or blindsense for 1d6 rounds if they fail their save.
