left eye lower than right eye, what is the issue and how can it be fixed? (Photo)

Eye asymmetry is very common, to varying degrees. The causes of eye asymmetry are many. Personal examination by an oculoplastic specialist is necessary. See following video.

The right upper eyelid is droopier than the left but both are affected.  You have a levator aponeurosis disinsertion ptosis.  This is repaired with a procedure call upper eyelid ptosis surgery.  Oculoplastic surgeons like posterior approach ptosis surgery but you are likely to do better with an anterior approach ptosis surgery.  There is no substitute for a detailed personal assessment.

eyelids can appear asymmetric reasons including position the eyebrows, position of the eyelid itself, relative prominence of the eyes, amount skin present on the eyelids, to name but a few.  I strongly suggest evaluation by skilled surgeon who specializes eyelid aesthetics to help you determine your best treatment options.

So everyone is a little asymmetrical. In your case this seems from this one photo to be a mild case of facial torsion where the eft side of your face is longer slightly than the right. I suspect your chin points a little right and your nose may even have a slight curve on it. It is almost impossible to treat unfortunately and in a mild case like yours I would not recommend it. Apologies but I hope that helps. Adam Goodwin

Thank you for your question. There are a variety of factors both static and dynamic that can affect eyelid position. These are best determined with an in-person exam and consultation. I suggest you see a fellowship trained Oculoplastic Surgeon or Plastic surgeon for an exam. This would provide the best chance of evaluation your issues.

From the photo you sent there is barely, if any,  discernible difference between the eyes and if there is, it may be  quite normal since most individuals, when looked at closely, have asymmetry between the left and right side of the face.  The problem for you is that if you seek out a treatment for something so minimal, you might find yourself in a situation which is worse than the one you started with.  Think it through carefully and get several professional opinion before you commit to any treatment. My advise, based on the singular photo, is to leave well enough alone.
Good luck,
