Well If it is that the LEFT is bigger it could be a number of things:
is acting fine. She's spayed, not current with shots, indoor cat who goes outside 2-4 times a week, never had fleas, ticks, or other illness of any kind it might be seizure there is a possibility that the presence of one pupil being bigger than the other is a sign that nueological damage is present.
or:
Head injury: always suspect when the eyes do not dialate simultaneously.
I suggest you have your kitty examined by your vet as soon as possible for a precise diagnosis and treatment as there is definately something going on.
your eye would explode
The lens and the pupil of the eye are two independent parts. The lens focuses light onto the Retina, and the pupil regulates the amount of light entering the eye. So, if the light intensity changed while you were focused on a particular object, the size of the pupil would change, but the lens focus would not.
if you did not have a pupil you wouldn't be able to see light. see light enters as the pupil gets smaller which allows more and more light to come in. and when the pupil gets bigger, then i woul say i Sucked my mommas titis
The stimulus in the pupil reflex would be light
There might be something wrong with the pupil. It may not be in the right position. I would recommend going to the eye doctor.
My favorite pupil will not be attending class tomorrow.
The black bit in you'r eye is called a pupil, the brown, green or blue bit around you'r pupil is called an iris.When you look into light you'r pupil gets smaller, but when you look into the dark you pupil get bigger.The reason for this is because you'r pupil is where you see out of, so when it is in the light you can see most things because there is a light and when it is dark you'r pupil gets bigger because you need to see more because it is darker and if you'r pupil was small at that time you would find it hare to see.
the pupil gets smaller
the pupil gets smaller because there is an abundance of light present.
The pupil is a hole surrounded by the iris which is the colored part of your eye. The pupil gets bigger and smaller because the iris expands or contracts to let more or less light in so you can see better. Have you ever noticed red-eye taken in a photo with flash. Well it is actually the light from the flash bouncing off of the back of your eye, if the pupil was a solid black dot it would not show the reflection coming out
None. There are no drugs (neither legal or illegal ones) that cause one's pupil color to change, neither when injected or taken any other way.
the pupil itself has the same job as a normal pupil would. It may look alittle diffrent depending on the person's condition. but otherwise no. it does not change
