why is my pupil bigger than the other
The pupil of one eye is larger than the other and this condition is observed in a disorder named as Anisocoria. The quantity of light that enters the eye is controlled by the pupil. The pupil narrows down in bright light and dilates in low light. The muscles in the Iris region show some problem in getting dilated and hence lead to Anisocoria.
Yes my sister is 23 and just recently noticed that one pupil is larger than the other. She just recently saw the eye doctor and he didnt notice it. She has been having headaches along with the weird pupils. She doesnt complain of sensitivity she just gets headaches.
