Causes of miosis: Pupillary constriction is called miosis. I presume it is just one pupil. There are multiple potential causes, some benign, and some indicating a dangerous condition. If the miosis is of recent onset, i advise a trip to the er. If it has been present for a while (months to years), you should see a neurologist or an opthalmologist. Don't ignore it.

Many things: Pupillary asymmetry needs evaluation. Many issues can make a pupil smaller or make the fellow pupil larger, resulting in asymmetry. See an eye doctor for further evaluation.

Exam to know: An exam would be helpful in this case. There are several possibilities. Aide's tonic pupil ( dilated then constricted ), horner's syndrome, argyll-robertson, pharmacological, poisons, neurological, hereditary, to name a few.
