If you mixed that with blindness (probably need to dip into 3E for true blindness), or with a necromancer's skeleton (mindless), or if a player puts on a blindfold deliberately to (try to) avoid the effect, what happens? (Perhaps 4E has creatures with immunity to fear because of their nature, so the skeleton example may or may not work.)
When I run 4E I decide what the wight is doing and describe it. Based on that description, using blindfolds or averting your eyes may have an affect on its Horrific Visage.
What I find interesting about 4E is that it's not hard to resolve crazy actions that follow from the fiction:
Player: What would happen if I got out a mirror and made it see its own Horrific Visage?
DM: (thinks about the game world) ... Do you know?
Player: No, that's why I asked!
DM: Okay, make a Religion check to find out.
Player: (success)
DM: Well, I think it's an old trope that evil spirits don't like to look at their own reflections. So yeah, it would probably get blasted back if it looked at itself. "Oh, the horror I have become reminds me of what I once was, and what I have lost."
Player: I'll do that then.
DM: Cool, make a Wis or Cha attack against Will for (page 42 high regular) damage. If you "bless" the mirror somehow - Undead Ward, maybe? - you could probably add some kind of proficiency bonus to that.
Player: Nice. Can I do that again without the Religion check?
DM: Sure, you know how it works now.
