How The World Would Look If You Had Cat Eyes

A recent study has shown that watching cat videos on the Internet is good for your health. In fact, watching “Grumpy Cat”, “Colonel Meow”, and all their other kitten friends purring and doing funny antics boosts your positive emotions and decreases your negative feelings. It might sound hard to believe, but you can’t argue with science!

Finally, we can safely say that the world is a better place because of cats. However, have you ever wondered how these little feline creatures view the world? What would it be like to look through a cat’s eyes?

Cat Vision vs. Human Vision

The basic difference between cat and human vision lies in the number of rods and cones. Cats have 6-8 times more rods in their eyes as compared to humans, whereas humans have more cones in their eyes than cats. Rods are responsible for peripheral and night vision, while cones are helpful in distinguishing between colors and provide better sight in the daytime.

Given that cats have extra rods in their eyes, they are able to see better in dim light or at night. Furthermore, rod cells refresh quickly, which is why cats’ eyes are very sensitive to the movement of objects. This makes cats very good hunters at night, as they can spot the movements of their prey very quickly.

Also, cats have a special reflective layer behind their retina called tapetum lucidum, which sends light that passes through the retina back into the eyes. This improves their ability to see in the dark, but it results in blurred images when light is abundant, which reduces a cat’s visual acuity in bright daylight.

Since cats have less cones in their eyes, their vision during the day is blurred and they can distinguish fewer colors as compared to humans. For example, cats are able to tell the difference between red, blue and yellow lights, but not much more than that.

Cats have a visual range of about 200 degrees as compared to the 180-degree range of humans.  Cat vision is blurred in comparison to humans. Objects at a distance of more than 20 feet appear blurry to a cat, whereas a human can see clearly up to almost 200 feet.

Therefore, it seems like the Internet’s favorite creature has more qualities aside from purring, dancing, sleeping and making people laugh.
