From a casual look at the photos, the most likely assumption would be that you have ptosis, which is a heavy upper eyelid. While this is the most likely possibility, another potential cause for your issue is enophthalmos. This is the medical term for an eye that sits deeper in the eye socket than normal. A prior history of an orbit fracture on the right side would be consistent with such a condition. There can also be a progressive condition called silent sinus syndrome where inner opening to the maxillary sinus closes due to scaring. This leads to a slowly progressive loss of maxillary sinus volume. The loss of sinus volume corresponds to a gain in eye socket volume. The eye socket sits directly above the maxillary sinus. The first step in addressing this issue is to make a firm diagnosis.
