Artist Nickolay Lamm, in consultation with renowned veterinary doctors from the All Animal Eye Clinic, The Animal Eye Institute, and the Ophthalmology group at Penn Vet, has established several ways by which cats see the world around them.
Lamm believes that the following is how a cat see things:
* Cats are nearsighted which affect their visual acuity. Humans with good eyesight can see sharply up to distances of 100-200 feet, but that would already look blurry to cats which need to be not farther than 20 feet from something to see it clearly.
* Cats see better in dim light and at night because they have six to eight times more rod cells in their retinas than humans which help them see in poor lighting conditions.
* Cats unlike humans can see rapid movements better than humans, again thanks to their rod cells that refresh more quickly. This explains why they are quick at catching their prey, including the elusive laser dot.
* Cats see less colors than people and the version of the colors they see is quite dull. Cats see things in limited hues so they can't distinguish between red, yellow, green and orange objects. What cats' photoreceptors can pick up well are wavelengths in the blue-violet and greenish-yellow ranges so that experts believe they can see mostly blues and grays. Lately, however, experts think cats also see some green.
