It is the retina that will convert the light rays into nerve impulses and send them to the brain. Light focuses on the retina through the cornea, pupil and lens. Lining the back of the eye is a light-sensitive tissue called the retina. Vertical pupils also change size much faster than round pupils.īehind the iris sits the lens.
It is widely accepted that the feature of vertical eyes is an adaptation to a nocturnal lifestyle, as this pupil shape excludes light more effectively. However, there are some big cats, such as Siberian tigers, who have circular pupils, similar to us. Domestic cats typically have vertical slit pupils. The smaller the pupil, the less light comes in, and vice versa. In high abundance of light, a cat’s pupils appear elliptical, while in darker conditions they are round, almost filling the entire iris area. Pupils are very sensitive to light changes, and they adjust to them accordingly. Light enters the eye through the pupils (the black area at the center of the eyes). The round, colored area of the eye is the iris. The cornea protects the eye and lets light in. In front of the eye is a clear dome cornea. The conjunctiva covers the inside of the eyelids.
The white part of the eye is called the sclera, and it’s covered with a thin membrane called the conjunctiva. The actual eyeballs are placed in bony cavities called the orbits. This is actually a key feature of all nocturnal animals. About your kitty’s eyesĪ cat’s eyes are significantly large in comparison to the size of its head.
