Cats' vision is known to be 7 times sharper than humans'.
But at the same time, cats see some things much worse than people.
What cats can't see
Cats can distinguish objects at a distance of 60 meters, but the optimal range at which a cat can clearly see objects is from 75 centimeters to 6 meters.
The cat sees nearby objects blurrily and recognizes them mainly using its sense of touch.
Another feature of cats' vision is that they see static objects worse than moving ones.
In addition, cats focus on objects moving in a horizontal plane. Vertical movements are more difficult for them to recognize.
Cats are also unable to perceive shades of brown, red and orange, and have difficulty distinguishing yellow, white and purple.
Cats can best distinguish between grey, green and blue colours, so the world from a cat's point of view is bluish-grey.
