Question

if u shine a light into the person's pupil, what will happen.pls tell me fastly​

Answer 1

• In bright light, it contracts. ... More light creates more impulses, causing the muscles to close the pupil. Part of the optic nerve from one eye crosses over and couples to the muscles that control the pupil size of the other eye. That's why the pupil of one eye can change when you shine the light into your other eye
