Your right eye appears to have droopy upper eyelid (eyelid ptosis) with brow elevation. See an oculoplastic specialist for evaluation and possible eyelid ptosis surgery, which can be done under local anesthesia. Skype consult available.

Your photograph is consistent with a weakness of the muscle of the eyelid known as ptosis ("toe-sis"). This condition requires a surgical repair if you want it corrected -- and it is making your eyes and face seem out of balance. In fact you will notice that your eyebrow on the side of the droopy lid is higher than on the other side. Please seek out an in-person consultation with a board-certified, fellowship trained Oculofacial Plastic Surgeon who specializes in cosmetic eyelid surgery and ptosis repair. This is a delicate and challenging operation that few surgeons perform well. Be realistic about the difficulty in achieving perfect symmetry between the eyelids -- it is something that i strive for every day in my career! Together with your surgeon you can decide if the benefits of repairing your eyelid will outweigh the challenges of the surgery. In my office this surgery is performed as an in-office, outpatient procedure which takes about an hour.  Best of luck in your search.
