1. Cats and humans have very different perspectives on the world, both literally and figuratively.
2. Artist Nickolay Lamm put together some visualizations to illustrate how cats see the world.
4. For each photo, the top view is what humans see and the bottom view shows the cat’s perspective.
5. Cats have a slightly broader visual field.
Cats have a visual field of 200 degrees compared to our 180 degrees. Peripheral vision for humans is 20 degrees on each side, which is shown in the images by the blurriness. Peripheral vision for cats is 30 degrees on each side, also represented by the blurriness, along with the extended width of the visualizations.
6. Cats can see 6 to 8 times better in dim light than humans.
Due to the high number of rods and because of their elliptical pupil, large cornea and tapetum.
7. While human vision is perfectly adapted for seeing sharply 100 feet away, cats can barely distinguish fine details past 20 feet.
8. Human retinas have many more cones than cats, which gives us vibrant and detailed day vision.
Cone cells are responsible for color vision as well as eye color sensitivity.
9. But cats have many more rods than humans, which enhances their ability to see in the dark.
Rod cells can function in less intense light than cone cells.
10. This is why they have those terrifying glowing eyes when you take photos with flash.
Cats have a tapetum lucidum, a reflective layer of tissue that bounces light that hits the back of the eye out through the retina again for a second chance to be absorbed by the rods.
11. Some research suggests that cats can see blue and yellow colors, but not red, orange or brown, which is why all the images look a little washed out.
Protanopic humans (red-green color blind) only see blues and yellows, so cats are probably like that, but with some green thrown in from a third cone type (making them trichromats).
