Eyelids are big and looking weird.

You have hollow sunken upper eyelids. You may benefit from filler injection. See video below for similar procedure on a young patient. You have mild upper lid ptosis but the bigger problem is the hollowness. See an oculoplastic specialist for evaluation to confirm above.

Your issue is levator dehiscence ptosis.  The tendon that opens the eyes is retracting into the orbit with the anterior orbital fat tissue.  To compensate for the heavy eyelid, reflexly you lift the eyebrows.  This makes it look like you do not have upper eyelid folds.  Doctors try to fill the sub-brow area without fixing the underlying problem-not physiologic.  It is far better in my opinion to have the corrective surgery to reposition the levator which also takes care of the thin eyelid situation.  A personal consultation is appropriate.

are certainly valid and fillers or fat will help with the hollowness.  If you want a better crease, you could have your lids lifted as well.  Schedule a consultation and discuss your options with your surgeon... and make sure he/she is qualified.
