Is it possible for the pupils of our eyes to dilate or contract individually one from another?
Answers:
Like others enjoy said, it's possible but it requires nerve damage or a condition that is not common (eg strabismus...possibly). I believe the optic chiasm is what prevents this from occurring (assuming it's healthy).
Since the reflex tract that controls this crosses over the midline, no. Unless, there is a problem with the nerve that reach the pupillary muscles but in that case one contracts and the othe does not. It is a BAD sign in brain injury.
Yes, but not normally. The normal response is for both pupils to constrict if a light is flashed within only one eye.
There are situations where one eye is damaged and the pupils counter differently. Look up the Marcus Gunn phenomenon.
only if you have brain or optical nerve harmed
