Is that supposed to be a pick-up line 囧 ?

[Radin539985]

What's this supposed to mean? :D

[PrimalSage]

I think it's what a westerner should expect to hear if they go to China

[grippygecko]

It means your eyelids don't have epicanthal folds (like an East Asian).
"all the better to see you with my dear..."

[RanzoG]

Why, thank you! And may I say: your eyes are very slanted.

[RobinThor]

Why not "your eye is round"?

Context. You would normally be talking about both eyes. You could say left or right eye if you wanted to make it clear that you only meant one eye.
