Wink Star

In anime, sometimes when a character winks a star is drawn coming out of their eye. Why does this happen? I have absolutely no idea. What does it mean? It means it's a wink strong enough to make stars come out. Most likely, it's done just because it looks cute.

• winku de hoshi ga deru
  ウィンクで星が出る
  A star leaves due to a wink.
  A star comes out with a wink.

This has basically nothing to do with star eyes.
