Cats can see almost as well as humans can, and at times better.
Cat vision is designed for detecting motion, useful for hunting. Like humans, cats have binocular vision, although not as well tuned as in humans. This means a cat most likely sees in 3-D, as do humans, which is very useful for judging distance. Cats appear to be slightly nearsighted, which would suggest their vision is tailored more for closer objects, such as prey, that can capture within running distance. Objects farther than several hundred yards rarely interest a cat.
