You´re talking about the differnce between eyes that have one lid or are double-lidded? Or about something else? I have double-lidded eyes. The ones with a wrinkle in them.

XD
I´m curious about "eye types" as well. Like, I wonder how the different shape of your eyes (rounded, more almond-shaped, tilted up or drooping....) can affect the way you apply eye makeup? Or maybe how to apply said makeup to make your eyes more rounded or almond-shaped, for example.
