Optical illusion. Amazing optical illusions that are confusing

Illusion is an optical illusion.

Types of optical illusion:

optical illusion based on color perception;
optical illusion based on contrast;
twisting illusions;
optical illusion depth perception;
optical illusion of size perception;
contour optical illusion;
optical illusion "shifters";
Ames room;
moving optical illusions.
stereo illusions, or, as they are also called: “3d pictures”, stereo pictures.

ILLUSION OF BALL SIZE

Isn't it true that the size of these two balls is different? Is the top ball larger than the bottom?

In fact, this is an optical illusion: these two balls are absolutely equal. You can use a ruler to check. By creating the effect of a receding corridor, the artist managed to deceive our vision: the top ball seems larger to us, because our consciousness perceives it as a more distant object.

ILLUSION OF A. EINSTEIN AND M. MONROE

If you look at the picture from close distance, you see the brilliant physicist A. Einstein.

Now try to move a few meters away, and... miracle, in the picture there is M. Monroe. Here everything seems to have gone without an optical illusion. But how?! No one painted on the mustache, eyes, or hair. It’s just that from afar, vision does not perceive some small details, and puts more emphasis on large details.

The optical effect, which gives the viewer a false impression of the location of the seat, is due to the original design of the chair, invented by the French studio Ibride.

Peripheral vision turns beautiful faces into monsters.

Which direction does the wheel spin?

Stare without blinking at the middle of the image for 20 seconds, and then move your gaze to someone’s face or just a wall.

ILLUSION OF WALL SIDE WITH WINDOW

On which side of the building is the window located? On the left, or maybe on the right?

Once again our vision has been deceived. How did this become possible? Very simple: the upper part of the window is depicted as a window located with right side buildings (we are looking from below), and the lower part is from the left (we are looking from above). And the middle is perceived by vision as consciousness deems necessary. That's the whole deception.

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, all the lines seem to be 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 visual system treats two images as part of a single scene. Therefore, it seems to us that both photographs are not symmetrical.

ILLUSION OF WAVY LINES

There is no doubt that the lines depicted are wavy.

Remember what the section is called - optical illusion. You're right, these are straight, parallel lines. And it's a twisting illusion.

Ship or arch?

This illusion is a real work of art. The painting was painted by Rob Gonsalves, a Canadian artist, representative of the genre of magical realism. Depending on where you look, you can see either the arch of a long bridge or the sail of a ship.

ILLUSION - GRAFFITI “LADDER”

Now you can relax and not think that there will be another optical illusion. Let's admire the artist's imagination.

This graffiti was made by a miracle artist in the subway to the surprise of all passers-by.

BEZOLDI EFFECT

Look at the picture and say in which part the red lines are brighter and more contrasting. On the right isn't it?

In fact, the red lines in the picture are no different from each other. They are absolutely identical, again an optical illusion. This is the Bezoldi effect, when we perceive the tonality of a color differently depending on its proximity to other colors.

COLOR CHANGE ILLUSION

Does the color of the horizontal gray line change in the rectangle?

The horizontal line in the picture does not change throughout and remains the same gray. I can't believe it, right? This is an optical illusion. To make sure of this, cover the rectangle surrounding it with a sheet of paper. This effect is similar to picture No. 1.

THE ILLUSION OF A SHINING SUN

This magnificent photograph of the sun was taken by the American space agency NASA. It shows two sunspots pointing directly at the Earth.

Something else is much more interesting. If you look around the edge of the Sun, you will see how it shrinks. This is truly GREAT - no deception, a good illusion!

ZOLNER'S ILLUSION

Do you see that the herringbone lines in the picture are parallel?

I don't see it either. But they are parallel - check with a ruler. My vision was also deceived. This is the famous classic Zollner illusion, which has been around since the 19th century. Because of the “needles” on the lines, it seems to us that they are not parallel.

ILLUSION-JESUS ​​CHRIST

Look at the picture for 30 seconds (it may take more), then move your gaze to a light, flat surface, such as a wall.

Before your eyes you saw the image of Jesus Christ, the image is similar to the famous Shroud of Turin. Why does this effect occur? In the human eye there are cells called cones and rods. Cones are responsible for transmitting a color image to the human brain under good illumination, and rods help a person see in the dark and are responsible for transmitting low-definition black-and-white images. When you look at a black and white image of Jesus, the sticks get tired due to long and intense work. When you look away from an image, these tired cells can't cope and can't transmit new information to the brain. Therefore, the image remains before the eyes and disappears when the sticks “come to their senses.”

ILLUSION. THREE SQUARE

Sit closer and look at the picture. Do you see that the sides of all three squares are curved?

I also see curved lines, despite the fact that the sides of all three squares are perfectly straight. When you move some distance away from the monitor, everything falls into place - the square looks perfect. This is due to the fact that the background causes our brain to perceive lines as curves. This is an optical illusion. When the background merges and we don’t see it clearly, the square appears even.

ILLUSION. BLACK FIGURES

What do you see in the picture?

This is a classic illusion. Taking a quick glance, we see some strange figures. But after looking a little longer we begin to distinguish the word LIFT. Our consciousness is accustomed to seeing black letters on a white background, and continues to perceive this word as well. It is very unexpected for our brain to read white letters on a black background. In addition, most people first look at the center of the picture, and this makes the task even more difficult for the brain, because it is used to reading a word from left to right.

ILLUSION. ILLUSION OF OUCHI

Look at the center of the picture and you will see a “dancing” ball.

This is an iconic optical illusion invented in 1973 by Japanese artist Ouchi and named after him. There are several illusions in this picture. First, the ball appears to move slightly from side to side. Our brain cannot understand that this is a flat image and perceives it as three-dimensional. Another deception of the Ouchi illusion is the impression that we are looking through a round keyhole on the wall. Finally, all the rectangles in the picture are the same size, and they are arranged strictly in rows without apparent displacement.

ILLUSION. ILLUSION OF THE COLOR OF WORDS

Say quickly and without hesitation the color of the letters in which the words below are written:

To some extent, this is not an optical illusion, but a puzzle. It is really difficult to name the color of a word, due to the conflict that arises between the left and right hemispheres. The right half is trying to say the color, and the left half is intensively reading the word, because of this, confusion arises in our minds.

ILLUSION-GREEN SHADES

You already guessed that the picture shows not two shades of green, but the same green color.

And you yourself can explain this optical illusion - the brain perceives them as different shades due to the contrast of the colors next to them. To check this, simply cover the environment with a sheet of paper.

PICTURE ILLUSION. SHLINKING TUNNEL

There will be no optical illusions here. To appreciate this illusion, you need to look at the center of the ball for a while.

The picture will reveal its capabilities in a few seconds. You will be able to see the tunnel begin to flash, some will see stronger "flashes". The illusion of flickering in this picture is associated with the peculiarities of black and white vision of the eye. As you know, special cells - rods - are responsible for it. If they are “overstressed,” these cells “get tired” and we see such an illusion.

PICTURE ILLUSION. SEA WAVES ON A PLATE

Look at the picture and you will see the illusion of a wave, as if the image “came to life.” To enhance the effect, you can move your head or eyes to the sides.

This illusion is associated with different colors(white and pink) intermediate links between peas. The white color is visible clearly and brightly, but the pink color, when you don’t look closely at it, merges with the green and becomes difficult to distinguish. And in the picture there is an illusion that the distance between the peas is changing.

PICTURE ILLUSION. SPIRAL GOING TO INFINITY

You ask: “Well, what is the illusion behind this picture? Regular spiral"

In fact, this is an unusual spiral, and it is not a spiral at all. This is an optical illusion! The picture shows regular completed circles, and the blue lines create the illusion of a spiral due to the swirling effect.

PICTURE ILLUSION. CUP OF WINE

What do you see in this picture? What is the illusion here?

If, in addition to the cup of wine, you saw two faces in the area of ​​the “leg” of the cup, looking at each other, you can be congratulated!

TO ARTICLE ILLUSION. WAVY SIDE OF SQUARE

Try and guess what kind of illusion is hidden in this picture.

If you see wavy lines sides of the squares - nothing surprising, because this is an illusion! Using a ruler, you can determine that the sides of the squares are straight and even.

OPTICAL ILLUSION. HIGH HAT

Estimate the height of the hat and its width and answer the question: “Are segments AB and CD equal?”

I really liked this optical illusion. It's incredible, but the height and width of the hat are exactly the same, i.e. segment AB is equal to CD. Due to the fact that the edges of the hat are curved on the sides, and the person’s face, on the contrary, is elongated, an optical illusion is created that the height of the hat is greater than the width. This can be explained by the fact that our brain takes into account the size of surrounding objects. If you measure the segments with a ruler or simply cover the person’s face with a sheet of paper, the optical illusion will disappear.

OPTICAL ILLUSION. GRAY DIAMONDS

Are all gray diamonds the same color? Isn't it true that the lower layers of the diamonds are lighter than the top?

The color of all diamonds is exactly the same. This optical illusion can again be explained by the environment. Our brain compares objects with environment, and an optical illusion occurs.

OPTICAL ILLUSION. A GIANT CHASES A Dwarf

Do you think the giant will catch up with the dwarf?

I will not give an answer to this question. But I know for sure that “fear has big eyes” and that these two figures are absolutely identical. Our consciousness is caught in an optical illusion; due to the corridor going into the distance, it perceives that the distant figure should be smaller.

OPTICAL ILLUSION. BLACK AND WHITE DOTS

The correct answer is 0. There are no black dots in the picture, all dots are white. Our peripheral vision perceives them as black. Because at lateral vision there is a displacement of the picture, but when we look directly at the same point, the optical illusion disappears.

OPTICAL ILLUSION. HORIZONTAL LINES

Do you see horizontal lines in the picture?

In fact, all the lines are not only parallel to each other, but also horizontal. You can use a ruler to check.

OPTICAL ILLUSION. SPIRAL

Is this a spiral? Is not it?

Take a closer look and you will see an optical illusion; in fact, these are even circles. But due to the geometric pattern and selected colors, the illusion of shifting lines of circles appears in the mind.

OPTICAL ILLUSION. PINK LINES

The picture shows pink lines crossing each other diagonally. Different shades, right?

In fact, the pink lines are completely identical to each other, they are the same shade of pink. This optical illusion is based on the contrast of colors surrounding the pink lines.

OPTICAL ILLUSION. LADDER

I ask you to answer the question: “Where does the staircase lead, up or down?”

The correct answer depends on which side you look at. If you imagine red as the front wall, then up, if yellow, then down.

OPTICAL ILLUSION. CUTS

Are the lengths of the left and right vertical segments equal?

You can use a ruler and make sure they are equal. Our vision was deceived by the “checkmarks” at the ends of the segments; you can cover them with a sheet of paper and make sure that our consciousness was under their influence.

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. Translated from Latin, the word “illusion” means “error, delusion.” This suggests that illusions have long been interpreted as some kind of malfunction visual system. Many researchers have been studying the causes of their occurrence.

Some visual illusions have long been scientific explanation, others still remain a mystery.

website continues to collect the coolest optical illusions. Be careful! Some illusions may cause tears, headache 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 an ordinary chocolate bar and make sure that this is not computer graphics, but a real-life riddle.

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 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 arranged in a circle pink spots 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

We are accustomed to taking the world around us for granted, so we do not notice how our brain deceives its own masters.

imperfection of our binocular vision, unconscious false judgments, psychological stereotypes and other distortions of worldview serve as the reason for the occurrence of 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

Impossible trident

Classic blivet is perhaps the most striking representative of optical patterns from the “impossible figures” category. No matter how you try, you will not be able to determine where the middle prong originates.

Another striking example is the impossible Penrose triangle.

It is in the form of a so-called “endless staircase”.

And also “The Impossible Elephant” by Roger Shepard.

Ames room

How does the Ames room work?

Movement Illusions

floating star

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

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

Old people/Mexicans

Lovers/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

Gray squares

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

Is the dress white and gold or blue and black?

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 shadows, which means White color 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, lightened due to the sun's rays directed at the dress and the poor quality of the photo.

In reality the dress was blue with black lace.

Here's another photo that baffled millions of users who couldn't decide whether it was a wall in front of them or a lake.

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 by overstimulating a 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, the yellow dots will disappear one by one. 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?

Our vision can very easily deceive our brain with simple color illusions, which surround us everywhere. Some of these illusions await you further.

How many colors are there in the picture?

Blue and green spirals are actually the same color - green. Blue color not here.

The brown square in the center of the top edge and the “orange” square in the center of the front edge are the same color.

Look carefully at the board. What color are cells “A” and “B”? Does “A” seem to be black and “B” white? The correct answer is below.

Cells “B” and “A” are the same color. Gray.

Does the lower part of the figure seem lighter? Close the horizontal border between the top and bottom parts figures.

Do you see a chessboard with black and white cells? The gray halves of black and white cells are the same shade. Grey colour perceived either as black or white.

The horse figures have the same color.

How many colors are there, not counting white? 3? 4? In fact, there are only two - pink and green.

What color are the squares here? Only green and Pink colour.

Optical illusion

We look at the dot, and the gray stripe on the orange background becomes... blue.

In place of the disappearing purple spots, a green spot appears, moving in a circle. But in reality it doesn’t exist! And if you concentrate on the cross, the purple spots disappear.

If you look closely at a point in the center of a black and white image for 15 seconds, the picture takes on color.

Look at the center of the black dot for 15 seconds. The image will turn into color.

Look at the 4 dots in the center of the picture for 30 seconds, then move your gaze to the ceiling and blink. What did you see?

At the intersections of all white stripes, with the exception of the intersection at which you fix your gaze this moment, small black spots are visible that are not really there.

Disappearance

If you look closely at the dot in the center for a few seconds, the gray background will disappear.

Concentrate your gaze on the center of the picture. After a while, the blurry color images will disappear and turn into a solid white background.
