Drooping or sagging upper eyelids can give the appearance that you are sad or tired. In addition to aesthetic concerns, you may experience functional problems. Sagging upper lids can interfere with one’s vision. As skin begins to sag on your lower eyelids, it can create the appearance of “bags” or dark circles under your eyes. In some cases, lower eyelids may even droop far enough to reveal the whites of the eye below the iris.
