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.
The drooping may be worse after being awake longer, when the individual's muscles are tired. This condition is sometimes called lazy eye, but that term normally refers to amblyopia. If severe enough and left untreated, the drooping eyelid can cause other conditions, such as amblyopia or astigmatism.
