A variation on this concept would be the SEP Field ("Someone Else's Problem" Field), found in Hitchiker's Guide to the Galaxy, replacing cloaking devices. You remain plainly visible, but nobody notices you because a tiny bit of their brains determines that you are someone else's problem, and therefore refuses to acknowledge you in any way.
The problem with this, though, is that it is probably a violation of the Laws, given that you are altering not what they see, but how they react to what they see.
As to the effect you're describing, it sounds to me as though you could get the effect you want by nailing the target with a Consequence ("Temporary Blindness"). This would be easily modeled by a damaging Spirit (light) attack. Or an AoE version thereof. You could then use your free compel to keep them from seeing you (or anything else) long enough to get away.
