How cats see Humans? #short

Technically, cats can see in color, but they probably see us — and everything else — in a very different light than we do. Cats have very few of the cones that respond to red light, so their world appears blue, gray, and yellow. Reds and greens are impossible for cats to tell apart, so if you have bright red hair, it probably doesn't stand out to your cat.

However, new research suggests that cats may be able to see some colors that humans can't. A new study by researchers in London found that cats and some other mammals can see colors at the ultraviolet end of the spectrum — colors that humans can usually only see under a black light. Given that there are many things in our world that possess ultraviolet coloration, such as birds and flowers, the world a cat sees may be an incredibly vivid one!

Glowing or not, if you're standing too far away from your cat, you may look like a big blur. Human eyes have muscles that allow them to change the shape of their lenses to focus on objects at different distances, but cats' eyes lack those muscles, so they are stuck focusing on things between 6 and 20 inches away.

In other words, cats are colorblind, nearsighted, and probably see the world as if it is lit by a black light.
