It's hard to describe, the skin above the left eyelid hangs over making it look like I don't have an eyelid on the left side, but it normal on the right side. The only way I can keep it looking remotely normal is by pulling the skin back up, but it seems to hang back down within seconds.

Anyone heard of this? Know if there's any name to this problem? I'm 15.

I've had that problem all my life with both eyes. It's just the way some people are designed. I had one eye worse than the other because I'd been clobbered in that eye, the area swelled up, bruised, and was never the same again.
I eventually had cosmetic surgery to correct the droopy skin. That was a failure because my forehead just settled down a little lower. Sounds crazy, but a second opinion said I should have had a forehead lift at the same time. I'm just meant to have no eyelids :)

Hi there,

I've got a similar problem, my eyelids have fallen a little lower, due to that I have extremely tired eyes, sought of a droopy eye lid.
