What specialist to see for uneven large eyes, 1 looks larger/bulging? (Photo)

F35 my eyes are uneven. Due to my dark features, it’s particularly obvious and I’ve been told by others I have a ‘bung’ eye. I believe they move correctly. But seems one lower lid is slightly downturned. I’m not sure what type of specialist to see or the cause. It’s becoming more pronounced with age and I’m growing increasingly self conscious. What can be done to even their appearance?
