Not for the faint of heart: how a girl turns her own face into creepy optical illusions. Amazing optical illusions that are confusing
Science
It's amazing how easy it is to deceive human brain.
Many magicians and (not only) use this, but we ourselves can test how gullible our brain is.
Here are 10 very interesting illusions.
Some of them will be very difficult to believe.
Optical illusions
1. Dali Illusion
Image of Salvador Dali in profile and a strange woman.
2. Rabbit or duck
Can you spot the rabbit and duck in this image? One looks to the right, and the other to the left.
3. Spinning silhouette of a dancer.
In this unstable illusion, movement can be seen both clockwise and counterclockwise. Early on there was a rumor that this illusion could be used to determine what kind of dominant hemisphere, however, this turned out to be a myth.
4. Crawling snakes (or spinning circles).
You see a picture in front of you in which the figures are moving. In fact, everything on it is static, and your brain perceives the elements of the picture as if they were moving.
5. The terrible illusion of Dr. Jekyll and Mr. Hyde.
You may see an angry face (on the left) and a calm one (on the right) in front of you. Now step away from the monitor. The further you move away, the more clearly you see how the faces change places, and there is a calm face on the left, and an angry one on the right. This illusion shows that sometimes what we see is not what we really see.
6. Afterimage of a girl.
Look at the red dot for 30 seconds. After this, look at the ceiling or any white surface (a wall, for example) and blink quickly several times. You will see a picture of the girl in color.
7 . Illusioncolors
Look carefully - parts A and B seem different colors. In fact, both pieces are the same color. To make sure of this, cover the junction of these parts with your finger.
8. Ponzo Illusion
Both green lines are the same length. This illusion takes advantage of the fact that the human brain displays everything in perspective, but it is only a 2D image.
9. Terrace
In this picture it is difficult to understand who is where.
10. MaskEinstein.
Marvelous. It doesn’t matter what we tell our brain, what matters is what the truth is. It is simply impossible to simply accept reality, instead of which we see an illusion.
We are accustomed to taking the world around us for granted, so we do not notice how our brain deceives its own masters.
The imperfection of our binocular vision, unconscious false judgments, psychological stereotypes and other distortions of worldview give rise to optical illusions. There are a huge number of them, but we tried to collect the most interesting, crazy and incredible of them for you.
Impossible figures
At one time, this genre of graphics became so widespread that it even received its own name - impossibilism. Each of these figures seems quite real on paper, but simply cannot exist in the physical world.Impossible trident
Classic blivet – perhaps the most bright representative optical drawings from the category " impossible figures" No matter how you try, you will not be able to determine where the middle prong originates.
Another shining example – impossible triangle Penrose.
It is in the form of a so-called “endless staircase”.
And also “The Impossible Elephant” by Roger Shepard.
Ames room
Issues of optical illusions interested Adelbert Ames Jr. early childhood. After becoming an ophthalmologist, he continued his research into depth perception, which resulted in the famous Ames Room.
How does the Ames room work?
In a nutshell, the effect of Ames's room can be conveyed as follows: it seems that in the left and right corners of its back wall there are two people - a dwarf and a giant. Of course, this is an optical trick, and in fact these people are of quite normal height. In reality, the room has an elongated trapezoidal shape, but due to false perspective it appears rectangular to us. The left corner is farther away from the visitors' view than the right, and therefore the person standing there seems so small.
Movement Illusions
This category of optical tricks is of greatest interest to psychologists. Most of them are based on the subtleties of color combinations, the brightness of objects and their repetition. All these tricks mislead our peripheral vision, as a result of which the perception mechanism gets confused, the retina captures the image intermittently, spasmodically, and the brain activates the areas of the cortex responsible for recognizing movement.floating star
It's hard to believe that this picture is not an animated GIF, but an ordinary optical illusion. The drawing has been created Japanese artist Kaya Nao in 2012. A pronounced illusion of movement is achieved thanks to the opposite direction of the patterns in the center and along the edges.
There are quite a few similar illusions of movement, that is, static images that appear to be moving. For example, the famous rotating circle.
Or yellow arrows on a pink background: when you look closely, they seem to sway back and forth.
Caution: This image may cause eye pain or dizziness in people with weak vestibular systems.
Honestly, this is a regular picture, not a GIF! Psychedelic spirals seem to drag you somewhere into a universe full of strangeness and wonder.
Changeling illusions
The most numerous and fun genre of illusion drawings is based on changing the direction of looking at a graphic object. The simplest inverted drawings just need to be rotated 180 or 90 degrees.
Two classic illusions-shifters: nurse/old woman and beauty/ugly.
A more highly artistic picture with a trick - when turned 90 degrees, the frog turns into a horse.
Other "double illusions" are more subtle.
Girl/old woman
One of the most popular dual images was published in 1915 in the cartoon magazine Puck. The caption to the drawing read: “My wife and mother-in-law.”
Old people/Mexicans
Elderly married couple or Mexicans singing with a guitar? Most first he sees old people, and only then their eyebrows turn into sombreros, and their eyes into faces. The authorship belongs to the Mexican artist Octavio Ocampo, who created many illusion pictures of a similar nature.
Lovers/dolphins
Surprisingly, the interpretation of this psychological illusion depends on the person’s age. As a rule, children see dolphins frolicking in the water - their brains, not yet familiar with sexual relationships and their symbols, simply do not isolate two lovers in this composition. Older people, on the contrary, see the couple first, and only then the dolphins.
The list of such dual pictures can be continued endlessly:
In the picture above, most people see the Indian's face first, and only then look to the left and see the silhouette in the fur coat. The image below is usually interpreted by everyone as a black cat, and only then does a mouse appear in its outline.
A very simple upside-down picture - something like this can be easily done with your own hands.
Illusions of color and contrast
Alas, human eye imperfect, and in our assessments of what we see (without noticing it ourselves) we often rely on the color environment and brightness of the object’s background. This leads to some very interesting optical illusions.Gray squares
Optical illusions of colors are one of the most popular types optical illusion. Yes, squares A and B are painted the same color.
This trick is possible due to the way our brain works. A shadow without sharp boundaries falls on square B. Thanks to the darker "surrounding" and the smooth shadow gradient, it appears to be significantly lighter than Square A.
Green spiral
There are only three colors in this photo: pink, orange and green. Don't believe me? This is what you get when you replace pink and orange with black.
Is the dress white and gold or blue and black?
However, illusions based on color perception are not uncommon. Take, for example, the white and gold that conquered the Internet in 2015 or black and blue dress. What color was this mysterious dress really, and why? different people Did you perceive it differently?The explanation of the dress phenomenon is very simple: as in the case of gray squares, everything depends on the imperfect chromatic adaptation of our visual organs. As you know, the human retina consists of two types of receptors: rods and cones. Rods capture light better, while cones capture color better. Each person has a different ratio of cones to rods, so the determination of the color and shape of an object is slightly different depending on the dominance of one or another type of receptor.
Those who saw the dress in white and gold noticed the brightly lit background and decided that the dress was in the shade, which means white should be darker than usual. If the dress seemed blue-black to you, it means that your eye first of all paid attention to the main color of the dress, which in this photo actually has blue tint. Then your brain judged that the golden hue was black, lighter due to the sun's rays directed at the dress and poor quality photo.
In reality the dress was blue with black lace.
And here is another photo that baffled millions of users who could not decide whether it was a wall in front of them or a lake.
Guys, we put our soul into the site. Thank you for that
that you are discovering this beauty. Thanks for the inspiration and goosebumps.

Even the most hardened skeptics believe what their senses tell them, but the senses are easily deceived.
An optical illusion is an impression of a visible object or phenomenon that does not correspond to reality, i.e. optical illusion vision. Translated from Latin, the word “illusion” means “error, delusion.” This suggests that illusions have long been interpreted as some kind of malfunction in the visual system. Many researchers have been studying the causes of their occurrence.
Some visual illusions have long had a scientific explanation, others still remain a mystery.
website continues to collect the coolest optical illusions. Be careful! Some illusions can cause tearing, headaches and disorientation in space.
Endless chocolate
If you cut a chocolate bar 5 by 5 and rearrange all the pieces in the order shown, then out of nowhere an extra piece of chocolate will appear. You can do the same with a regular chocolate bar and make sure that it doesn’t computer graphics, but a real-life mystery.
Illusion of bars
Take a look at these bars. Depending on which end you are looking at, the two pieces of wood will either be next to each other, or one of them will be lying on top of the other.
Cube and two identical cups
Optical illusion created by Chris Westall. There is a cup on the table, next to which there is a cube with a small cup. However, upon closer examination, we can see that in fact the cube is drawn, and the cups are exactly the same size. A similar effect is noticeable only at a certain angle.
Illusion "Cafe Wall"
Take a close look at the image. At first glance, it seems that all the lines are curved, but in fact they are parallel. The illusion was discovered by R. Gregory at the Wall Cafe in Bristol. This is where its name came from.
Illusion of the Leaning Tower of Pisa
Above you see two pictures of the Leaning Tower of Pisa. At first glance, the tower on the right appears to lean more than the tower on the left, but in fact both of these pictures are the same. The reason is that the visual system views the two images as part of a single scene. Therefore, it seems to us that both photographs are not symmetrical.
Disappearing circles
This illusion is called "Vanishing Circles". It consists of 12 lilac pink spots arranged in a circle with a black cross in the middle. Each spot disappears in a circle for about 0.1 seconds, and if you focus on the central cross, you can get the following effect:
1) at first it will seem that there is a green spot running around
2) then the purple spots will start to disappear
An optical illusion is an impression of a visible object or phenomenon that does not correspond to reality, that is, an optical illusion. Some visual illusions have long had a scientific explanation, others still remain a mystery.
Optical illusions: optical illusion
The information collected by our eyes is in some way inconsistent with the source. Optical illusions can cause serious headaches. Therefore, such things need to be treated with caution.
There are three main types of illusions:
1. Literal optical illusions
These optical illusions are considered the simplest. They are characterized by a difference in the image (that is, the perception of the image) and the actual tangible objects that make up the picture.
A literal optical illusion makes us see completely different objects or figures from those shown in the pictures.
2. Physiological optical illusions
These illusions affect the eyes and brain through overstimulation. certain type(brightness, color, size, position, tilt, movement).
3. Cognitive optical illusions
These illusions are the result of our brain's misperceptions and unconscious inferences.
We continue to collect the coolest optical illusions. Be careful: Some of them can cause tearing, nausea and disorientation.
So, each of the following optical illusions can blow our minds
Do you see three pretty girls?
Now let's flip the image
Our brain rarely encounters upside-down images, so it cannot notice distortions in them
Illusion 13 people
Initially we see 12 people here, but after moving, another one appears, the 13th
Which way is the window open?
You can change direction just by thinking about it
Distortion of perception of movement
These blocks do not move one after another - their speed is the same
Fill color
Look at the black dot in the center. Keep looking at it as the picture changes.
Did you see a color photo? Now take your eyes away from the point.
Contrast simulation
The squares on the left side seem to be darker than the squares on the right
However, they are actually the same color
Ames room
Room irregular shape, used to create a three-dimensional optical illusion, was designed by American ophthalmologist Albert Ames in 1934
Dynamic brightness gradient
Slowly move your eyes closer to the screen and the “light” in the middle will become brighter
Move it back and it will become weak again.
Vanishing points
Focus your gaze on the green dot in the middle
After a while yellow dots will disappear one after another. In fact, they remain in place, it's just that static frames disappear from our consciousness if they are surrounded by constantly changing images.
Four Circles Illusion
None of them actually intersect
Droste effect
Droste effect - looping recursive image
Illusion of perception
The color of the stripe in the center is actually uniform and the same along the entire length
moving poster
Roll your mouse wheel up and down and you will see the poster “moving”
Selective perception
There are two photos here, and there is one difference between them
Try to find it, and once you notice the difference, it will be impossible not to see it.
Optical illusions: pictures
Which of these faces belongs to a woman and which to a man?...
Wrong... The pictures show the same face
Is this the same picture? Yes.
There is NO lake in the picture
Tilt your head and look closely at the image
This is not a bird
The picture shows a painted female figure
This floor is flat
These two monsters are the same size
The orange dots in both pictures are the same size
How many legs does an elephant have?
Are you sure of what you see?
What a wonderful picture of cars.
Or are they toy cars?
Makeup - terrible force. And sometimes really scary. Do you want to get a charge of surprise and slight shock? Then take a look at the work of one talented makeup artist. The heroine of this material turns own face into extraordinary (and creepy!) optical illusions. This is where the unusual talent lies.
Any girl knows: if you have the desire and a kilogram or two of cosmetic products, you can easily paint yourself a new face. But some makeup artists perceive this simple truth too literally. Just like the heroine of this review.
For many young people, the sight of their attractive (at first glance) friend without makeup can lead to a slight shock. But here are the friends of the Canadian makeup artist Mimi Choi are more likely to be shocked by her makeup. After all, with the help of cosmetics, the girl paints shockingly real optical illusions on her face. Extra eyes, slits, bones outward - photographs of such makeup make you shiver, but look at them carefully. And suspect photoshop.
But Mimi claims that photographs of her makeup cannot be retouched. And the whole secret is in large quantities time spent, patience and drawing ability. It’s not for nothing that Mimi worked as a school teacher, but left teaching for a career as a makeup artist. What now, having gained considerable fame thanks to social networks, has no regrets.
