When should I worry about uneven pupils?

One pupil may be bigger than normal, or one pupil may be smaller than normal, resulting in unequal pupils. In most cases, anisocoria is mild, constant and no cause for concern.

What does it mean if one pupil is larger 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.

The muscles themselves may tire and the ability to keep the pupil open may fade. Therefore, both pupil size and stability can objectively identify sleepiness and sleep deprivation.
