One eye feels smaller than the other when I touch it, and it looks smaller and is higher up than the other eye a little bit.
My smaller eye has more upper eyelid on it because it is deeper in its socket than the other eye is.
I have had this my entire life. I can see it in pictures when I was a young child.
For years I have noticed the difference in my eyes, and it causes me emotional distress. (even knowing facial asymmetry is normal)
