Mantis shrimps (Stomatopoda) Mantis shrimps probably have the most sophisticated vision in the animal kingdom. Their compound eyes move independently and they have 12 to 16 visual pigments compared to our three.
Human Vision. Eagles and other birds of prey are the kings of the animal kingdom when it comes to visual acuity. Their retinas are not only packed with light-detecting cone cells, but they also have a much deeper fovea—a cone-rich structure in the back of the eye—which acts like a telephoto lens on a camera.
As a group, the Aborigines have significantly better visual acuity than the Europeans. This was true for both monocular and binocular vision. Some Aborigines have acuities below the previous postulated threshold levels. Aborigines as a group also have the previous postulated threshold levels.
Huskies are known for their captivating eyes, but this pup is especially striking. As you might have already guessed, this doggo has heterochromia, a condition in which the two irises of the eyes can be totally different colors.
Humans – Best Mammal Vision
In comparison to the rest of the animal kingdom, humans have very good eyesight. We can see objects with clarity from far distances, have strong depth perception and can distinguish between up to 1 million different colors.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
Hazel is the most attractive eye colour in females
Only green eyes seemed to suffer at all, with only 11% of matches reached. Blue and brown, the most popular for men, trended towards the bottom middle of the list, with brown eyes - the most common in the world - receiving only 13% of all matches.
However, it is more common in the animal kingdom: A number of animals commonly have amber-colored eyes, including wolves, dogs, cats, eagles, owls, pigeons and fish. In fact, eyes this color are sometimes referred to as “wolf eyes.”
1. Quokkas. The quokka, a pint-sized marsupial native to the islands off the coast of Australia and distantly related to kangaroos and wallabies, is nearly always smiling.
Aboriginal and Torres Strait Islander adults experience bilateral vision impairment and blindness 3 times more than non-Indigenous adults.
Mantis shrimps probably have the most sophisticated vision in the animal kingdom. Their compound eyes move independently and they have 12 to 16 visual pigments compared to our three. They are the only animals known to be able to see circular polarised light.
Most dogs have only about 30 to 60 degrees of binocular overlap versus approximately 140 degrees cats and humans. But dogs are champions when it comes to visual field of view. That means when King looks straight ahead he can still see 240 degrees, compared to 200 degrees in cats and 180 degrees in humans.
People with purple eyes make up less than 1% of the world's population. This means purple, or violet, is truly one of the rarest eye colors across the globe. Finding accurate statistics for eye color is always a bit tricky because large-scale studies and data are few and far between.
Red/Pink Eyes
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink.
Amber eyes are extremely rare. Most sources say that only about 5% of people have true amber eyes. Coming up with a hard and fast number or percentage, though, is not as easy as you might think—there simply haven't been enough large-scale studies done to quantify eye color prevalence with certainty.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Although chitons look very simple, these mollusks have a very sophisticated shell. Its outer layer contains up to 1000 tiny eyes, each a bit smaller than the period at the end of this sentence.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
And what would you think is the most attractive eye color? In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%).
The shape of Asian eyes has been compared to almonds by Westerners for centuries.
