As you are now probably aware, upper eyelid ptosis is a condition that causes the upper eyelid to appear to be droopy or give a person that sleepy-eye appearance. With this condition, the upper eyelid is lower than it should be (it either covers part of the iris or is very close to covering the iris) and this is caused by a weak eyelid muscle.
As you look at your eye, a sizable part of your iris (the eye's colored circle) should be visible above your pupil, and no part of the pupil itself should ever be covered by the eyelid. If you have ptosis, the drooping eyelid narrows your eye's opening, which makes your affected eye appear smaller than normal. You also may lose the crease (fold of skin) that normally lies between your upper eyelid and eyebrow.
