Ah! surely can mean "to blink". But I think the verb is not used in this meaning outside that phrase.

But this is not what is written here. It says "[it] flashes/twinkles from [their] eyes". I need more context to understand this, but this seems like some kind of figurative phrase, related to the "the eyes are the windows to the soul" metaphor.
