сверкнула очками

Здравствуйте!
Что значит "сверкнула очками"?
Заранее большое спасибо!!


– Вы нашли шапку? – сверкнула очками Чучурина. Кивинов понял, сейчас будет скандал.

That means what it should mean, quite literal sense.

-Have you found the hat? - Chuchurina's glasses flashed...


Well, maybe, her glasses flashed because her eyes had flashed with anger or something else first . That's why Kivinov had realized that's a quarell with her was inevitable and was just about to break out

большое спасибо!!

That is a kind of wordplay. There is a bookish cliche: "она сверкнула очами" - "her eyes flashed".
