One of two things:
1. Upon making eye contact, her pupils allowed less light, thus making them grow larger to compensate for vision loss.
2. Something about looking at you struck some sort of emotional or physiological. Maybe fear, surprise, lust, anger, romance, or less light in her pupils, just to name a few.
I saw this on the Discovery Channel once; it means they find you attractive. Pretty cool huh?
pupils will only get bigger if your in a dark room, if his eyes get bigger, hes checking you out
he might like you
It means he fancies you or he has got some problem with his eyes.
its not just parakeets its everyones eyes when light enters the eye the pupil doesnt get bigger its the color around the pupil that gets bigger or smaller the pupil is wut the light goes through. then it reflects againts the back of your eye and that's how you see things
it gets bigger
They change because when the cat is focusing on a specific object the pupil gets bigger to keep focus, when the pupil is a diamond shape that then means that the cat/kitten is not focusing on something particular
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.
Smaller because the eye is protecting it's self from the light
They become bigger and widder
each human has a black circle in there eye which is called a pupil,when someone is in the light the pupil does not need that much light so it gets smaller but if it is in a dark area the pupil gets bigger because the eye needs lots of light to indicate where the person is going
Contracts
It depends on how much light your eyes receive, in dark places or when you close your eyes your pupils dilate (mydriasis) to increase the ammount of light they can take in, conversely, when looking at an intense light the pupils contract (miosis) to decrease the ammount of light. This is called the photomotor reflex and involves the sympathic (mydriasis) and parasympathic (miosis) nervous pathways.
