Your right upper lid appears to be slightly lower than the left in your photos. This is called blepharoptosis or ptosis and may be congenital or acquired. The tearing problem may be a blockage of tear flow anywhere in the system from the eyelids to the nose (puncta, sac, nasolacrimal duct). An Oculoplastic surgeon could clarify your diagnoses, discuss options with you, and let you know the costs. Best wishes.
