Quick Answer
Unequal pupil size can be normal, but it can also reflect differences in nerve control or eye health. Doctors call unequal pupils anisocoria.
The Full Story
Many people have a slight difference in pupil size that is harmless and stable. The pupils are controlled by the autonomic nervous system, so changes in light, medications, or nervous system function can create asymmetry. A sudden difference, especially with pain, drooping eyelid, or blurred vision, can signal an eye or neurological problem. For that reason, new anisocoria is something clinicians take seriously.
