Is there such a thing as a vision test for cats? - Animal Hospital of Statesville

Typically, vision testing in cats involves watching them manipulate and move about, holding their heads still and gently bringing a hand up to their face to see if they blink appropriately. We move a cotton ball, drop a cotton ball, and see if they will track something. Cats can sometimes just stand there and stare, being scared or mad, or they don't know what to do. You can be sure they can see you, but they're not responding to anything, they turn their head, or they don't want to participate in what you're doing. We can shine the lights in their eyes and see if their pupils move correctly, which may have some suggestion of vision, but it's not always an easy test in cats.
