What does it mean when one of your pupils is bigger than the other?
Normally the size of the pupil is the same in each eye, with both eyes dilating or constricting together. The term anisocoria refers to pupils that are different sizes at the same time. The presence of anisocoria can be normal (physiologic), or it can be a sign of an underlying medical condition.

Can lack of sleep cause constricted pupils?
How Pupil Size Relates to Sleep Loss. Moreover, your pupils’ overall size will shrink, perhaps reflecting fatigue in the task of maintaining the larger size. The muscles themselves may tire and the ability to keep the pupil open may fade.

Do your pupils change size when you see someone you love?

This surge in hormones appears to make your pupils dilate. Dilation may also be related to the biological need to reproduce.
