Sharpest night vision. Who has the best vision in the world? The sharpest vision in the world

It is with the help of sight that a person perceives most information from the surrounding world, therefore, all the facts related to the eyes are of interest to a person. Today there are a huge number of them.

Eye structure

Interesting facts about the eyes begin with the fact that man is the only creature on the planet with the whites of the eyes. The rest of the eyes are filled with cones and rods, like some animals. There are hundreds of millions of these cells in the eye and are light-sensitive. Cones respond to changes in light and color more than rods.

In all adults, the size of the eyeball is almost identical and is 24 mm in diameter, while a newborn child has an apple diameter of 18 mm, and the weight is almost three times less.

Interestingly, sometimes a person can see various floating opacities in front of their eyes, which are in fact threads of protein.

The cornea of \u200b\u200bthe eye covers its entire visible surface and is the only part of the human body that is not supplied with oxygen from the blood.

The lens of the eye, which provides clear vision, constantly focuses on the environment at the speed of 50 objects per second. The eye moves with the help of only 6 eye muscles, which are the most active in the entire body.

Interesting facts about the eyes include information that sneezing with open eyes is not possible. Scientists explain this by two hypotheses - a reflex contraction of the facial muscles and the protection of the eye from the ingress of microbes from the nasal mucosa.

Brain vision

Interesting facts about vision and eyes often have evidence that a person actually sees with the brain, not the eye. This statement was scientifically established back in 1897, confirming that the human eye perceives surrounding information upside down. Passing through the optic nerve to the center nervous system, the picture turns over to its usual position precisely in the cerebral cortex.

Features of the iris

These include the fact that each person's iris has 256 distinctive characteristics, while fingerprints differ in only forty. The likelihood of finding someone with the same iris is almost zero.

Violation of color perception

Most often, this pathology manifests itself as color blindness. It is interesting that at birth all children are color blind, but with age, most of them return to normal. Most often, this disorder affects men who are not able to see certain colors.

Normally, a person should separate seven primary colors and up to 100 thousand of their shades. Unlike men, 2% of women suffer from a genetic mutation, which, on the contrary, expands the spectrum of their perception of colors to hundreds of millions of shades.

Alternative medicine

Given the interesting facts about him, iridology has spawned. It is an unconventional method for diagnosing diseases of the whole body using the study of rainbow

Darkening the eye

Interestingly, the pirates did not wear blindfolds to hide their injuries. They closed one eye so that he could quickly adapt to the poor lighting in the ship's holds. By alternately using one eye for dimly lit areas and brightly lit decks, pirates were able to fight more effectively.

The first tinted glasses for both eyes appeared not to protect against bright light, but to hide the view from prying persons. At first, they were used only by Chinese judges, so as not to demonstrate personal emotions to those around them.

Blue or brown?

Human eye color is determined by the amount of concentration in the body of the pigment melanin.

It is located between the cornea and the lens of the eye and consists of two layers:

• front;
• rear.

They are defined in medical terms as mesodermal and ectodermal, respectively. It is in the front layer that the coloring pigment is distributed, determining the color of the human eyes. Interesting facts about the eyes confirm that only melanin provides color to the iris, no matter what color of the eye. The shade changes only by changing the concentration of the dye.

At birth, almost all children have this pigment completely absent, so the eyes of newborns are blue. With age, they change their color, which is fully established only by the age of 12.

Interesting facts about human eyes also state that the color can change depending on some circumstances. At the moment, scientists have established such a phenomenon as a chameleon. It represents a change in the color of the eye during prolonged exposure to the cold or with prolonged bright light. Some people claim that the color of their eyes depends not only on the weather, but also on their personal mood.

The most interesting facts about the structure of the human eye contain data that in fact all people in the world are blue-eyed. The high concentration of pigment in the iris absorbs light rays of high and low frequencies, due to which their reflection leads to the appearance of brown or black eyes.

Eye color depends a lot on geographic location. So in the northern regions the population with blue eyes prevails. Closer to the south, there are a large number of brown-eyed, and at the equator, almost the entire population has a black iris.

More than half a century ago, scientists established interesting fact - at birth we are all farsighted. Vision is normalized only by the age of six months. Interesting facts about human eyes and vision also confirm that the eye is fully formed by physiological parameters by the age of seven.

Vision can affect general condition organism, so when the eye strain is exceeded, general fatigue, headaches, fatigue and stress are observed.

Interestingly, the relationship between the quality of vision and the carrot vitamin carotene has not been scientifically proven. In fact, this myth dates back to the war, when the British decided to hide the invention of the airborne radar. They attributed the rapid detection of enemy aircraft to the keen eyes of their pilots who ate carrots.

To test your visual acuity yourself, you should look at the night sky. If near the middle star the handles big bucket (Big Dipper) you can see a small star, then everything is normal.

Different eyes

Most often, such a disorder is genetic and does not affect overall health in any way. Different eye colors are called heterochromia and can be complete or partial. In the first case, each eye is colored with its own color, and in the second, one iris is divided into two parts with different colors.

Negative factors

Most of all, cosmetics affect the quality of vision and eye health in general. Wearing tight clothing also has a negative effect, since it impedes the blood circulation of all organs, including the eyes.

Interesting facts about the structure and work of the eye confirm that a child is not able to cry in the first month of life. More precisely, there are no tears at all.

The composition of a tear has three components:

• water;
• slime;

If the proportions of these substances on the surface of the eye are not observed, dryness appears and the person begins to cry. With an abundant flow, tears can directly enter the nasopharynx.

Statistical studies claim that every man cries on average 7 times a year, and a woman 47.

About blinking

Interestingly, on average, a person blinks 1 time in 6 seconds, more reflexively. This process provides the eye with sufficient moisture and timely cleansing of impurities. According to statistics, women blink twice as often as men.

Japanese researchers have found that the blinking process also acts as a reboot for concentration. It is at the moment of closing the eyelids that the activity of the neural network of attention falls, and therefore blinking is observed most often after the completion of a certain action.

Reading

Interesting facts about the eyes did not miss such a process as reading. According to scientists, the eyes get tired much less with fast reading. At the same time, reading paper books is always a quarter faster than electronic media.

Misconceptions

Many people believe that smoking does not affect the health of the eyes in any way, but in fact, tobacco smoke leads to blockage of the vessels of the retina and leads to the development of many diseases. optic nerve... Smoking, both active and passive, can lead to lens opacity, chronic conjunctivitis, retinal macula, blindness. Also, when smoking, lycopene becomes harmful.

In normal cases, this substance has a beneficial effect on the body, improving vision, slowing down the development of cataracts, age changes and protecting the eyes from ultraviolet radiation.

Interesting facts about the eyes contradict the notion that monitor radiation negatively affects vision. In fact, eye damage is caused by excessive stress when you often focus on small details.

Also, many are sure of the need to carry out childbirth only by the cesarean route if a woman has poor eyesight... In some cases, this is true, but with myopia, you can take a course laser coagulation and to prevent the risk of retinal rupture or detachment during labor. This procedure is carried out even in the 30th week of gestation and takes only a few minutes, without having a negative effect on the health of both the mother and the child. But be that as it may, try to regularly visit a specialist and have your vision checked.

If you say that a cat has, you are wrong

People can see well in the dark, but nocturnal animals like cats will give us a hundred points ahead. But who is the owner of the most sensitive eyes?

The human eye is one of the most amazing achievements of evolution. He is able to see fine dust particles and huge mountains, near and far, in full color. Working in tandem with a powerful processor in the form of the brain, the eyes allow a person to distinguish between movement and recognize people by their faces.

One of the most impressive features of our eyes is so well developed that we don't even notice it. When we enter from a bright light into a semi-dark room, the level of illumination of the environment drops sharply, but the eyes adapt to this almost instantly. As a result of evolution, we have adapted to see in bad light.

But on our planet there are living beings who see in the dark much better than human... Try reading a newspaper in deep twilight: black letters merge with a white background into a blurry gray spot, in which nothing can be understood. But a cat in a similar situation would not have experienced any problems - of course, if she could read.

But even cats, despite their habit of hunting at night, are not the best at seeing in the dark. Creatures with the sharpest night vision have evolved unique visual organs that allow them to capture literally grains of light. Some of these creatures are able to see in conditions where, from the point of view of our understanding of physics, in principle, nothing can be seen.

To compare night vision acuity, we will use lux, which measures the amount of light per square meter. The human eye works well in bright sunlight, when the illumination can exceed 10,000 lux. But we can see with just one suite - about that much light happens on a dark night.

Domestic cat ( Felis catus): 0.125 lux

Photo from www.listofimages.com

Cats need eight times less light to see than humans. Their eyes are generally similar to ours, but their design has several features that make it work well in the dark.

Cat eyes, like human eyes, are made up of three main components: the pupil, the opening through which light enters; crystalline lens - a focusing lens; and the retina, a sensitive screen onto which the image is projected.

In humans, pupils are round, while in cats they have the shape of an elongated vertical ellipse. During the day they narrow into slits, and at night they open to their maximum width. The human pupil can also change size, but not within such a wide range.

A cat's lens is larger than a human's, and is able to collect more light. And behind the retina, they have a reflective layer called the tapetum lucidum, also known simply as the "mirror." Thanks to it, cats' eyes glow in the dark: light passes through the retina and is reflected back. Thus, light acts on the retina twice, giving the receptors an additional chance to absorb it.

The composition of the retina itself in cats is also different from ours. There are two types of light-sensitive cells: cones, which distinguish colors but only work in good light; and sticks - not perceiving color, but working in the dark. Humans have many cones, giving us rich, full-color vision, while cats have many more rods: 25 per cone (in humans, this ratio is one to four).

There are 350 thousand rods per square millimeter of the retina in cats, and only 80-150 thousand in humans. In addition, each neuron leaving the feline retina transmits signals from about one and a half thousand rods. A weak signal is thus amplified and converted into a detailed image.

This sharp night vision also has a downside: in the daytime, cats see much like people with red-green color blindness. They can distinguish blue from other colors, but they cannot tell the difference between red, brown and green.

Tarsier ( Tarsiidae): 0.001 lux

Photo from the site www.bohol.ph

Tarsiers are tree-dwelling primates found in Southeast Asia. Compared to the rest of their body proportions, they appear to have the largest eyes of any mammal. The body of a tarsier, if you do not take the tail, usually reaches a length of 9-16 centimeters. The eyes, on the other hand, have a diameter of 1.5-1.8 centimeters and occupy almost the entire intracranial space.

Tarsiers feed mainly on insects. They hunt early in the morning and late in the evening, when the illumination is 0.001–0.01 lux. Moving along the tops of trees, they should look out for small, well-camouflaged prey in almost complete darkness and at the same time not fall, jumping from branch to branch.

They are helped in this by their eyes, which are generally similar to human eyes. The giant tarsier eye lets in a lot of light, and its amount is regulated by the strong muscles surrounding the pupil. A large lens focuses the image on the retina, strewn with rods: the tarsier has more than 300 thousand of them per square millimeter, like a cat.

These large eyes have a disadvantage: tarsiers are unable to move them. In compensation, nature has endowed them with necks that rotate 180 degrees.

Dung-beetle ( Onitis sp.): 0.001-0.0001 lux

Photo from the site www.bbc.co.uk

Where there is dung, there are usually dung beetles. They choose the freshest pile of manure and begin to live in it, rolling balls of manure in reserve or digging tunnels under the pile to equip themselves a pantry. Dung beetles of the genus Onitis fly out in search of dung in different time days.

Their eyes are very different from human eyes. The eyes of insects are faceted, they consist of many structural elements - ommatidia.

In beetles flying during the day, ommatidia are enclosed in pigment membranes that absorb excess light so that the sun does not blind the insect. The same shell separates each ommatidium from its neighbors. However, in the eyes of nocturnal beetles, these pigment membranes are absent. Therefore, the light collected by many ommatidia can be transmitted to only one receptor, which significantly increases its light sensitivity.

Genus Onitis combines several different types dung beetles. In the eyes of daytime species there are insulating pigment membranes, the eyes of evening beetles summarize signals from ommatidia, and in nocturnal species signals from a number of receptors are summed twice as many as in evening ones. Eyes of the nocturnal species Onitis ayguluse.g. 85 times more sensitive than daytime eyes Onitis belial.

Halictid bees ( Megalopta genalis): 0.00063 lux

Photo from the site www.bbc.co.uk

But the rule described above does not always apply. Some insects can see in very low light, despite the fact that their visual organs are clearly adapted for daylight.

Eric Warrent and Elmut Kelber of Lund University in Sweden found that some bees have pigment membranes in their eyes that isolate ommatidia from each other, but they nevertheless are excellent at flying and looking for food on a dark night. For example, in 2004, two scientists demonstrated that halictid bees are able to navigate in light that is 20 times less intense than starlight.

But the eyes of the haliktid bee are designed to see well in daylight, and in the course of evolution, the bees had to adapt their organs of vision somewhat. After the retina has absorbed the light, this information is transmitted to the brain via nerves. At this stage, the signals can be summed to increase the brightness of the image.

These bees have special neurons that connect ommatidia into groups. This way, the signals coming from all the ommatidia in the group are fused together before being sent to the brain. The image is less sharp, but much brighter.

Carpenter bee ( Xylocopa tranquebarica): 0.000063 lux

Photo from the site www.bbc.co.uk

Carpenter bees, found in the mountains called the Western Ghats in southern India, see even better in the dark. They can fly even on moonless nights. “They are able to fly in starlight, cloudy nights and strong wind"Says Hema Somanathan of the Indian Institute for Science Education and Research in Thiruvananthapuram.

Somanathan found that carpenter bees' ommatidia have unusually large lenses, and the eyes themselves are quite large in proportion to other parts of the body. All this helps to capture more light.

However, this is not enough to explain such excellent night vision. Perhaps, among carpenter bees, ommatidia are also combined into groups, like their counterparts. Megalopta genalis.

Carpenter bees do not only fly at night. “I've seen them fly during the day, with predators ravaging their nests,” Somanathan says. - If you blind them with a flash of light, then they simply fall, their vision is not able to process a large amount of light. But then they come to their senses and take off again. "

It seems that of all the fauna, carpenter bees are endowed with the most acute night vision. But in 2014, another contender for the champion title appeared.

American cockroach ( Periplaneta americana): less than one photon per second

On the splash screen there is a photo from the site www.activepestsolutionsltd.co.uk

It is impossible to directly compare cockroaches with other living things, because their visual acuity is measured differently. However, their eyes are known to be unusually sensitive.

In a series of experiments described in 2014, Matti Weckström of the University of Oulu in Finland and his colleagues investigated how individual light-sensitive cells in cockroach ommatidia reacted to very low light. They inserted the thinnest electrodes made of glass into these cells.

Light consists of photons - massless elementary particles. The human eye needs at least 100 photons to hit it in order to feel something. However, the receptors in the cockroach's eyes responded to movement, even if each cell received just one photon of light every 10 seconds.

The cockroach has 16-28 thousand receptors in each eye that are sensitive to green color. According to Vekström, signals from hundreds or even thousands of these cells are summed up in dark conditions (recall that up to 1,500 optic sticks can work together in a cat). The effect of this summation, in the words of Vekstrom, is "grandiose", and it seems that it has no analogues in nature.

“Cockroaches are impressive. Less photon per second! Says Kelber. "This is the sharpest night vision."

But bees can beat them in at least one respect: American cockroaches don't fly in the dark. “The flight is much more difficult - the insect moves quickly and colliding with obstacles is dangerous,” comments Kelber. “In this sense, carpenter bees are the most amazing. They are able to fly and get food on moonless nights and still distinguish colors. "

Man is the highest intelligent being on Earth, but some of our organs are significantly inferior to our smaller brothers, one of which is vision. At all times, people were interested in how the world birds, animals, insects see, because outwardly everyone's eyes are so different, and today's technologies allow us to look at them through the eyes, and believe me - the eyesight of animals is very interesting.

Such different eyes

Animal eyes

First of all, everyone is interested in - how do our closest friends see and?

Cats can see perfectly in pitch darkness, as their pupils can expand up to 14 mm, thereby capturing the slightest light waves. In addition, they have a reflective membrane behind the retina that acts as a mirror, collecting all the particles of light.

Cat pupils

Due to this, a cat sees in the dark six times better than a person.

In dogs, the eye is arranged in approximately the same way, but the pupil is unable to expand so much, thereby giving an advantage over a person to see in the darkness four times.

What about color vision? More recently, people were sure that dogs see everything in shades of gray, without distinguishing a single color. Recent studies have proven that this is a mistake.

Dog color spectrum

But the quality of night vision comes at a price:

1. Dogs, like cats, are dichromats, they see the world in faded blue-violet and yellow-green colors.
2. Visual acuity is lame. In dogs, it is about 4 times weaker than ours, and in cats, 6 times. Look at the moon - see spots? Not a single cat in the world sees them, for her it is just a gray spot in the sky.

It is also worth noting the location of the eyes in animals and in our country, due to which pets see with peripheral vision no worse than with central vision.

Central and peripheral vision

Another interesting fact is that dogs see 70 frames per second. When we watch TV, 25 frames per second for us merge into a single video stream, but for a dog it is a fast sequence of pictures, which is probably why they do not really like watching TV.

Except for dogs and cats

A chameleon and a seahorse can look in different directions at the same time, each of its eyes is processed separately by the brain. The chameleon, before throwing out his tongue and grabbing the victim, still looks down to determine the distance to the victim.

But an ordinary pigeon has a viewing angle of 340 degrees, which allows you to see almost everything around, which makes hunting difficult for cats.

A few dry facts:

• Deep-sea fish have superdense retinas, each millimeter of which contains 25 million rods. This exceeds ours with you a hundred times;
• The falcon sees a mouse in the field from a distance of one and a half kilometers. Regardless of its flight speed, the clarity is completely preserved;
• The scallop has about 100 eyes at the edge of the shell;
• The octopus has a square pupil.

Reptiles surpassed everyone a little. Pythons and boas can see infrared waves, that is, heat! In a sense, we also “see” it with our skin, but snakes see it with their eyes, like a predator in the film of the same name.

Mantis shrimp

But the most unsurpassed eyes are of the mantis shrimp. It's not even an eye, and an organ stuffed with wave sensors. Moreover, each eye actually consists of three - two hemispheres, separated by a strip. Visible light is perceived only by the middle belt, but the hemispheres are sensitive to ultraviolet and infrared ranges.

Shrimp sees 10 flowers!

This is not counting the fact that the shrimp has trinocular vision, in contrast to the most common on the planet (and we have) binocular.

Insect eyes

Insects can also surprise us a lot:

• An ordinary fly is not so easy to kill with a newspaper, as it sees 300 frames per second, which is 6 times faster than us. Hence the instant reaction;
• A domestic cockroach will see movement if the object has moved only 0.0002 millimeters. This is 250 times thinner than a hair!
• The spider has eight eyes, but in fact they are practically blind insects, able to distinguish only a spot, their eyes practically do not work;
• The bee's eye consists of 5,500 microscopic lenses that cannot see red;
• The earthworm also has eyes, but atrophied. He can tell day from night, nothing more.

Bee eyes

Dragonflies have the sharpest eyesight among insects, but it is still about 10 times worse than ours.

What is the sight in animals, visual video

Eagles have the best eyesight of all living things. They are able to see a hare from a height of 3 km.

Eagles have two pairs of eyelids that protect their unusually keen eyesight. They use one pair when sitting still or on the ground. However, it is enough for them to fly into the air, as the second eyelids or, more precisely, transparent blinking membranes immediately descend on their sovereign eyes. Their task is to protect the bird's eyes not only from the pressure of air (when the eagle dives at great speed), but also to cover them from the branches of trees or bushes or from the prey itself. The sun can also create problems, especially at the altitudes reached by large birds of prey. This membrane covers the eyes to keep them clean and clear.

Eagles' eyesight is well developed.
They are characterized by both a wide field of vision and binocularity, that is, stereoscopic perception with two eyes. A bird, hovering hundreds of meters above the ground, is able to notice the movement of a tiny field mouse. The accommodation of the eagle's vision occurs very quickly and accurately, both in terms of depth and sharpness. His vision is so sensitive that the bird is capable of searching an area of \u200b\u200b5 square miles (13 km. Sq.) With great care. The eagle's field of view is 275 degrees. This allows him not only to observe what is happening on his side, but also to notice when someone approaches from behind. At the time of the birth of an eagle chick, its eyes are far from being so strongly developed, and the vision of this magnificent hunter reaches perfection only as it matures and matures.

The eagle is able to easily identify potential prey from a distance of one and a half to two kilometers, and by moving its head additionally, it can almost double this distance.

The eagle benefits from the ability to gain great altitude. Firstly, it allows him to notice a thunderstorm, storm and danger from a distance, and secondly, to see the prey and the source of food. Birds such as crows or wild turkeys rarely fly high and have a limited field of vision. The situation is similar with us.

Eagles distinguish colors - an unusual phenomenon in the wildlife. Moreover, in reality, they perceive color shades much more clearly than people, thanks to which they better feel the beauty of the earth. Eagle eyes also have another peculiarity: inside the eyeball is a kind of comb that acts like a gyroscope, allowing extremely precise navigation. The eyes of the eagle are placed far apart on the sides of the head, which allows him to feel the depth of space - to determine the height and distance. When a bird dives at a speed of 100 km / h, it must quickly and accurately estimate the distance to the ground - otherwise, it will not escape trouble.

We all know how important our eyes are. We receive most of the information, experiences and memories through our eyes. And, of course, we can enjoy the exceptional creations of nature that surround us. Some animals also have incredible or even more amazing eyes than humans. Here are the Top 10 Most Amazing Eyes in the Animal Kingdom.

The frog's large eyes are remarkable from several angles. First of all, this amphibian spends a decent amount of time in the water. To swim in water filled with debris, frogs have three eyelids - two transparent and one translucent eyelid. This translucent membrane can close completely to allow the frog to protect its eyes underwater.

The position of the frog's eyes also gives it a better field of vision. The eyes are located on the sides of the head to receive full overview 360 degrees. Frogs can even see what is happening outside when they are submerged in water.

Is a small primate found in the forests of Southeast Asia. Its most striking feature is its large eyes, which measure up to 1.6 cm in diameter. Compared to the size of the body, these are the largest eyes of any mammal in the world. Just like an owl's, a tarsier's eyes cannot move. Because they are anchored in the skull.

Instead, tarsiers can move their head 180 degrees left and right. This helps them know what's going on around them. They are nocturnal animals that only become active at night. But their large eyes provide them with excellent night vision. They also have a keen sense of hearing. Both of these qualities help tarsiers locate prey in low light conditions.

The hammerhead shark has one of the weirdest but interesting heads - in the form of a flattened hammer with wide-set eyes. But research has shown that this strange head has a good purpose. It provides the hammerhead shark with much better vision than other shark species. More precisely, such wide-set eyes give them excellent vision and exceptional depth perception.

The cuttlefish is an incredible sea creature that can instantly change its color. This allows cuttlefish to quickly hide from predators, mixing with the environment. This remarkable power of cuttlefish is the assistance of specialized skin cells and their incredible vision. They have strange "w" shaped pupils that give them a wider range of vision. Interestingly, they can even see what is behind them.

Plus, they can detect polarized light with incredible accuracy. Even the slightest change in the angle of polarized light. This gives the cuttlefish a clear idea of \u200b\u200bwhat exactly is happening around them.

Do rectangular goat pupils seem strange to you? But at the same time, they provide impressive vision. For a grazing animal such as a goat, this is the most sought-after strength.

Because having good vision, the goat has more chances to escape from the predator. Its rectangular pupils provide detailed panoramic vision. This helps the goat to detect danger from a distance. In addition, effective eye rotation also helps detect strange movements in the field even while grazing. Thus, they have enough time to escape from the predatory animal.

1500 people live in warm climatic regions of the world different types geckos. Most of them are nocturnal animals. To adapt to this lifestyle, they have impressive eyesight. To be precise, their eyes are 350 times more sensitive than human vision and threshold. color vision... Geckos can even see colors in low light with amazing quality. This is a rare power in the animal kingdom.

One of the amazing things about dragonflies are their large, globular eyes. Each dragonfly eye is made of 30,000 facets and is positioned in different directions. The result is incredible 360-degree vision. This allows them to detect even the slightest movement in their environment.

Dragonflies can also detect ultraviolet and polarized light that is outside of our visual spectrum. All these qualities play a huge role in dragonflies' navigation.

Owls have very interesting, large front eyes. This positioning of the eyes offers a great advantage for owls - incredible binocular vision or the ability to see an object with both eyes with great depth perception. Even animals and birds with eyes on the sides of their heads do not have such excellent vision.

Surprisingly, instead of eyeballs owl eyes are shaped like pipes. Moreover, their eyes cannot rotate like ours. But they can move their head 270 degrees in the left and right directions. This gives owls a much broader vision. To adapt to their nocturnal lifestyle, owls also have excellent night vision, which brings in millions of light-sensitive retinal rods.

Chameleons are so famous for their ability to change color. But their visual system is just as amazing as their ability to change color. These reptiles can move their eyes independently of each other. That is, they can focus on two different objects in two different directions at the same time. This incredible power of the chameleon eyes provides superior 360-degree vision. Chameleons can also focus on objects at incredible speed.

The mantis shrimp has the most fantastic visual system in the animal kingdom. We humans have three color receptors. But this unusual crustacean has 12 different color receptors. These mantis shrimp see so many colors that we cannot even understand.

Beautiful eyes can also rotate independently of each other in different directions at the same time. Eye rotation capacity is measured up to 70 degrees. This provides a broader vision for this little creature. In addition, the mantis shrimp, like other animals with exceptional vision, can detect infrared, ultraviolet and polarized light.
