Iris The circular muscles of the <b>iris</b> expand and contract the pupil. The size of the pupil determines how much light will enter the eye, so the iris effectively controls the amount of light that is passed to the retina. The iris is also responsible for eye color (blue, brown, green, hazel). See the related link below for more information on the iris.
In human eyes, this size variation of the pupil is controlled by a circular ciliary muscle, but this limits the amount of size variation. In cats however, the same process is controlled by two, shutter-like ciliary muscles, which gives the cat itâs characteristic slit-like pupil in bright light conditions. All cats pupils are therefore elliptical. However, the pupils of some (notably the âBig Catsâ) appear more circular when dilated.
