Thank you for your question. By doing some research you are probably aware that the term for your situation is called ptosis, which is the drooping of the upper eyelid. Since there is no history with the question you submitted, I'm going to assume that you've had this problem for a while and perhaps recently it got worse.
First of all, you need to consult with an ophthalmologist or an oculoplastic specialist just to rule out any other medical issues that may cause ptosis to occur. One option is to use drops that have dilating action used by ophthalmologists to help stimulate the muscle and temporarily lift the eyelid. In my experience, the best option for drooping eyelids is ptosis surgery.
In my practice, ptosis surgery is a common procedure which we do under local anesthesia. We use a little bit of sedation, and it is important we do this with the patient's cooperation because the muscle is very sensitive. We ask patients to open their eyes, look up and have them sit to make sure the height, shape and contour is good.
The point is that you can have surgery to improve the appearance, it should be done to get the best symmetry possible. I hope this was helpful and thank you for your question.
