Research overview: the area centralis and the limits of feline acuity

Unlike the primate fovea, the cat's region of sharpest vision is a broader, shallower zone called the area centralis. This survey reviews what is known about its photoreceptor and ganglion cell composition and the behavioral acuity it supports. Estimates of feline visual acuity typically fall around a small fraction of human acuity, meaning cats see roughly the detail a person with significantly reduced vision would. That coarse resolution is the price of an eye optimized for dim light and movement. The area centralis still provides the cat's best detail for judging a pounce, but cats rely heavily on whiskers and hearing to refine close-range targeting where their eyes cannot focus sharply. Comparing the feline area centralis with the primate fovea highlights how nocturnal predators and diurnal foragers solved the sensitivity-versus-resolution problem differently.
