since it has no face it could be representing any emotion
like fear or anger or pleasure or excitement
it works for everything!
The way the lens covering are bent can convey a few emotions.
Upper half down = dissatisfied -_-
Lower half up = glee ^_^ twitching if done fast.
Both halves near closed = suspicious > _ >
Upper half bent = angry \ _ /
Scope out = surprise O _ O
