the whole spectrum turns red.
If there is a problem with the muscles of the pupil then it will not regulate light into the eye correctly.
With high intensity light your pupil constricts. This happens to protect your retina from damage by light of high intensity.
They die.
it gets bigger
Nothing. AFTER the light is detected and calibrated, the pupil may change size.
If the pupil of the eye did not work, than your eye could not regulate light entering it.
When a light is not shined into an eye the pupil contracts gets bigger because the eye needs all the light being presented to it. If the light is not taken away the pupil does not dilate. PS like the eye gets smaller in the light.
in bright light the pupil shrinks
They become bigger and widder
Light Pupil Dilate was created in 2001.
The eyes constrict, not dilate, when a light is shone into the eye...this is a multi-arc process going through the parasympathetic nervous system and the EW nucleus.
The pupil allows light to enter the eye.
