If it is congenital ptosis, the patient can only be corrected by surgery. If the patient is tired for a long time, resulting in eye fatigue and ptosis on one side, you can first increase the rest time and observe at home for a period of time. If it is not seen for a long time, the upper eyelid can be restored to its original position by surgery.
I suggest you go to the hospital for an eye examination first to see if an eyelid droops because of some inflammation or other eye diseases. Don't rush to the hospital for surgical correction, because a drooping eye may also be caused by local inflammation. It is necessary to make clear the cause before deciding the treatment.
