The pupil appears as the dark central part of the eye. The pupil can change size (through changes in the iris) in order to regulate the amount of light going through it.
WitrynaThe sclera, which is the white part of the eye, is a resilient outer coating. The function of this structure is to protect the eyeball. The clear cornea is connected to the sclera and its role is vital in the process of vision. The cornea is responsible for bending light that passes through it, doing so in order to establish focus.
