what is she looking for?

The title on Pixiv is ﾒｶﾞｰﾒｶﾞｰ, which means "My eyes, my eyes!" Guess she got some dust in them or something.

Judging from that question mark and the way she's moving her hand, I would say that she lost her "eye" or forgot where she put it. Kinda like how someone would lose a pair of glasses.

I assume a play on the classic "Where are my glasses?" "On top of your head."

The "eye" seems very unamused.

A wordplay?
"Megane Megane… (Where are my glasses?)" <-> "Megaa Megaa (My eyes, my eyes!)"

EDIT: Added megane megane.
