I can often tell that my face is drooping when others don't see it. I think it's partly because when we look at someone, we usually see their face as a whole and don't notice subtle differences in the details. When we look at our own face in a mirror, we tend to see every "flaw." If your daughter is like me, she can probably feel the difference in muscle strength and tension when there's a change, and because of that feeling she knows exactly where to look. It may be that one eyebrow is slightly lower than the other or that one side of her mouth doesn't rise the same distance as the other when she smiles. We sometimes see and are aware of things about ourselves that are harder for others to see.
Hope that your daughter and you are doing well. Wishing all the best for both of you! ❤️ wm

my left eye feels only half open to me but others notice only a small difference. The nerve receptors from the brain can play tricks. Sounds like your daughter is looking for answers - why is this happening? Hope all goes well, cheers Trev B

Hi Johanna. My facial changes are often very subtle. My hubby usually notices very well if something is off. My left eye that has the double vision sometimes is centered strangely compared to other eyeball. Take care.🙂😇🙏
