Droopy lid/dilated pupil

Hey, I'm 21 and over the past two years I've noticed that one of my upper eye lids is a bit "Droopy" at times. The left one, and over the past few years I've also noticed that the pupil in that eye is sometimes considerably larger than the right. Not all the time, more noticeable at night. If I look at my eyes in the mirror its like my left pupil is dilated and my right pupil is going crazy trying to compensate and fix itself to my left one.  I dont experience any problems with my vision, no blurriness, and I dont think i suffer from any headaches more than the normal person would.  I was wondering if this is at all a thing I should worry about, my slightly at times droopy lid with a slightly dilated pupil. thanks!

There are a number of possibilities.

It is unlikely that it is anything "bad" but I would feel better if
you were checked by a neurologist or neuro-ophthalmologist.
Worst case would be an early third nerve paresis caused by
an aneurysm. Very unlikely with your age and symptoms but
get it checked just to be sure.

More likely that you have an Adie's tonic pupil and a coincidental
slight ptosis (droopy lid) when you are tired and the eyelid  muscle relaxes.
