You are kind of wrong... There are two paths of percepting things, one is slower but you are getting conscious of what you're percepting and another one is faster and can prompt you to act before you are aware you're seeing something. See here []. There are people who can't see, yet they can grasp a small object with accuracy or navigate in a room they don't know - it's called blindsight []. But if it is how Erza does it, Kyouka's curse must turn off rather certain areas of the brain or neural pathways than the receptors.

Also, it shouldn't be so easy :P
