Tag for eye glints/gleams?

Is there a tag for when someone has a glint or gleam in their eye (or their teeth)?

Examples please.

Darkrai in post #499704, though what sticks in my mind most are the "Shiny Teeth"(Rock Lee) and Colgate(Paranoia Agent) shorts in AMV Hells 4 & 3, respectively.

sparkle could work, maybe? Something like post #447111, although I don't think that's exactly what you're talking about.

Let's add post #488895 to the fire: "sparkles" off of objects.
