I'm a 14yr old Asian girl who has noticed my uneven and weird eyelids. I want to know what's up and what I can do? (photo)

I am 14 and I've noticed my eyelids are uneven and and I'd like to know why. I've come up with things like ptosis but I'm not sure and wanted to ask someone to see what's wrong but I'm not sure if it's serious enough or not. I've also noticed that my eyeball location seems to change depending on if I stay up on my phone or not. If I stay up on my phone in the dark, my left eye seems to go higher than the other but if I don't then it looks even. When I was little my eyelids were a bit uneven too.
