One thing you are seeing is the absence of pigmentation of the eyelid. This is not abnormal. Can you send a couple more pics of her whole face?
From these photos the right eye opening may be slightly smaller. So the pigmentation difference and opening diameter are not the same as the other eye but unless accompanied by other abnormalities there is no problem. Slight differences in eyelid openings are normal in people and pets. Be sure to have your vet check her eyes on her first and followup exams.
