For example (and I'm not anywhere near close a competent artist, butI know it's true) these here.
The cornea pokes out, it's convex, and the iris is kind of concave, so if you draw it that way you get instant "compentence points" even if the result is shitty.
Also, the upper lid has usually its higher point closer to the nose (aka the inner side) and the lowest point of the lower lid is usally on the outside side.
The eyeball is also round, that's why you get those suggested creases that are higher up than the suggested eyelid volume lines.
Since eyelids are comparable to lips on your mouth.
If you know the essences (like these are a selection of) of a thing, then you can take that and morph them.
You could draw an almost square eye, but if you make the highest point of the upper lid a bit closer to the nose, and the lower point of the lower lid a bit closer to the side, and add a line to hint at lid thickness, and a crease higher up (below the brow, in the eyesocket) to hint at a fold of skin.
Then even that square eye would look more *real* than just a rigid square.
If you gave it a cornea with highlights that juts out a bit further than the iris, too.
Etc.
