There is one pupil in each eye. The pupil is the opening in the center of the iris that allows light to enter the eye. Its size can change depending on the lighting conditions to regulate the amount of light entering the eye.
There are many ways to compare the shape of the pupil in a dissected eye with our own pupil. One is to examine general diameter.

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 left one goes in the left eye and the right one goes in the right eye... ;)
I'm guessing (an educated guess) that the cloudy eye is blind.Usually, when an eye becomes blind, it gets clouded over. I don't know why.
No! As long as the kitten's eye looks normal and has a pupil then it's fine. I have a semi-feral kitten who is blind in one eye. His eye is completley gray with no pupil. The kitten and his brother have brown eyes, apart from the blind eye which is gray! :P
A double pupil is a condition a person may be born with. There is a smaller pupil or opening adjacent to the normal pupil. It is still located within the iris and does not affect one's vision. This in old times was known as a "witch's eye". Thank you, Matt E.
The odd word is orchid.While both the orchid and iris are flowering plants, the three terms retina, pupil and iris are all parts of the eye, while orchid is not.
I will quote Escher's comment on this print. "The pupil reflects the one that watches us all."
he got in a fight with his friend and the doctor's couldn't mend his eye fully so one eye is blue and the other is brown due to pupil dilation.
The constriction of pupils in response to bright light is called the pupillary light reflex. If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response).This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils. It is considered involuntary since you don't think about it.
