A selection of optical illusions and double-digit pictures.
The eyes are complex mechanism which helps a person to perceive correctly the world. But as practice shows, even such a seemingly perfect mechanism can be easily deceived.
This can be done using color contrasts, sharply changing proportions and various kinds small details. Thanks to all this human eye will see an optical illusion that changes depending on the angle at which you look at it.
Optical illusion
Optical illusion (visual illusion)- this is an incorrect perception of certain pictures or surrounding objects by the eyes. In this case, the eyes see the image a little differently than the brain tells them. The correct background, depth and geometric shapes arranged in a certain sequence help to achieve a similar effect in the picture.
All these little tricks prevent the eyes from correctly scanning the image in front of them, and as a result, the brain forces the person to see a distorted picture. Surrealist artists take full advantage of this feature of the human eye and try to surprise people with paintings that have a special meaning. That is why surrealism can also be classified as an optical illusion that can provoke a person to strong emotions.
Illusion pictures for the eyes
As you probably already understood, illusion pictures force our brain to perceive images not exactly as they look. This happens because the brain also has patterns, and if it understands that the eyes do not perceive the picture quite correctly, it begins to send impulses that make it completely different.
The brain can also be tricked using bright color. If the same picture is superimposed on a different background, then it individual parts the eyes will perceive in a different color.
People are even more misled by pictures that depict geometric shapes that are contrasting in color. At first glance, it may seem to a person that they are located parallel to each other. But in fact, if you look more closely at them, you can understand that they are looking in opposite directions.
And, of course, don’t forget that a loving picture looks different from different angles. In view of this, if you make it contrasting, you will see different depths in it. This can be seen in the example with a contrasting cube.
Stereo image to improve vision
3D stereo image
3D picture
3D stereo images- this is nothing more than the same optical illusions, simply created by alternating dots and textures. Main principle Such pictures are based on the brain’s ability to compare different data and estimate distances to objects, figures and points as accurately as possible.
Such images are very often used for eye training in the treatment of ophthalmic pathologies. According to experts, if a person looks at such pictures for at least a few minutes a day, his eyes will relax properly.
In order to correctly see the stereo image, you will first need to move away from it at arm's length and try to completely relax your eyes. You should try to look through the image. If you do everything correctly, after some time you will see the most realistic three-dimensional picture.
Three-dimensional picture in black and white
Black and white flats
If you carefully read our article, you probably realized that illusion pictures work best with color contrast. This is why black and white images are the easiest to deceive our eyes. If you just look at the simplest picture in this color scheme, you will notice that your eyes jump from one element to another, not knowing where to stop.
That is why, when looking at such an optical illusion, it seems to a person that the figures in the image are constantly moving, floating and moving. If, for example, a portrait of a person is depicted in such a color scheme, then depending on the color it will change both its contour and its shape.
Eyes see movement due to correctly selected colors
The good thing about moving pictures is that they create a realistic effect. When a person looks at them, it seems to him that he really sees a waterfall or a sea that sways. The best thing in this case is that a person does not need to take absolutely any action to see everything correctly. As a rule, at the first glance at such a visual illusion, the eyes immediately catch the movement of some individual details.
Geometric moving picture
In case this happens geometric picture, then it will be created using contrasting shades and identical geometric shapes. In this case, the eyes will perceive it almost the same way as black and white image, thanks to which it will seem to a person that the drawing is always in motion.
The square can only be seen when turning
The picture shows how you can visually enlarge an object
GIFs, like any other illusion pictures, deceive the human eye and it does not perceive them exactly as it did initially. In this case, everything is built on movement. It is from the speed and in which direction the elements move that a person can see different images.
Also, gifs allow you to visually reduce large objects quite well and enlarge very small ones. This happens by moving closer or further from the object you will be looking at.
Optical illusion with depth effect
Hypnosis picture concentrating attention on the central point
Hypnosis pictures- these are images that can lead a person into lung condition trance promoting relaxation nervous system. Most often, this effect is achieved with the same contrast and the same type of lines or figures, placed from largest to smallest. Looking at the image, a person tries to understand the secret of the continuous movement of objects in his field of vision.
And the more he tries to solve the riddle of the hypnosis picture, the more he plunges into a kind of trance. If you try long time look into the center of such an optical illusion, then it will inevitably begin to seem to you that you are moving along some kind of corridor or simply falling somewhere. This state will cause you to relax and forget about everyday problems and obstacles for a while.
The double meaning of minimalism
Mirror optical illusion
The main secret of double optical illusions is the almost complete repetition of all, even the smallest lines. This creates a mirror effect that allows you to create an image that will look different from different angles. In this case, you can combine two completely different designs in the picture, as long as they fit each other perfectly in shape and color scheme.
Also double picture may consist of two completely different images, just when you look at it you will see the outlines of the same figure.
Pictures for visual deception for children
In principle, visual illusion pictures for children are also based on the contrast of colors, the depth of lines and a correctly selected background. It’s just that, unlike images for adults, in this case, upside-down pictures are most often used.
By looking at them, the baby tries to recognize what his eyes actually see, thereby helping him develop logical thinking. And in order to make it easier for small children to perceive what they see, as a rule, the drawings depict animals or plants that are familiar to them.
For example, this could be a drawing that depicts a cat that turns into an angry dog when it turns over.
In addition, children perceive very well pictures in which the same object has different lengths. In this case, the illusion effect is achieved by the correct background and different colors two figures completely identical in shape.
Geometric illusion
Geometric illusions- this is nothing more than an image of objects of different shapes, which the eye perceives not quite as is customary in geometry. In this case, the ability of the human eye to determine the color, direction and size of objects is used.
But if in geometry they are arranged according to certain rules, then in this case, for example, a rectangle can be composed of several triangles of different sizes. This illusion is designed so that a person, instead of seeing triangles, will look at parallel lines and try to understand how similar they are.
Also in geometric illusions, contrast in size is very often used. Looking at such an image, a person does not see that the two central circles are the same size. Even when looking closely, he thinks that the circle surrounded by smaller objects is larger than the one surrounded by larger ones.
Pictures of optical illusion with a dress
If you spend a lot of time on the Internet, then you have probably already come across a picture with a question about the color of a dress. As a rule, people cannot give a definite answer to this question as in different time day they see a different shade of the outfit. What is this connected with? As already mentioned at the very beginning of our article, the human eye is a rather complex mechanism, the main one of which is the retina (responsible for the correct perception of color).
The retina itself consists of rods and cones, the number of which determines how brightly a person perceives a particular color. For this reason, the dress may appear soft blue to some people, while deep blue to others. When it comes to optical illusions, lighting plays a huge role. In daylight it will appear lighter, but in artificial light it will appear much brighter and darker.
Picture for optical illusion – “Girl or old woman”
Each of us has experienced the “Girl or Old Woman” optical illusion at least once in our lives. But, having looked at it, we simply forget about it and don’t even think about why our eyes see such a dual picture. In fact, in this case, completely two different images are skillfully connected to each other in one drawing.
If you pay closer attention, you will realize that one pattern flows smoothly into the other. For example, the oval of a young girl’s face simultaneously serves as the nose of an old woman, and her ear serves as the eye of an elderly woman.
Tattoo imitating the flight of a butterfly
Surreal tattoo
Tattoo with volumetric effect
As you probably already understood, an optical illusion is nothing more than a correctly drawn picture. Therefore, if you wish, you can easily get yourself a tattoo in the style of surrealism.
All you have to do is apply it using contrasting colors, the right directions and background. All this will help you create voluminous and even visually moving images on your skin. You can see an example of a tattoo in the style of surrealism a little higher.
Mirror surfaces in the interior
Optical illusions are good because they can radically change any room. Mirror surfaces are considered the simplest visual deception. With their help, even the smallest room will seem huge and bright.
Horizontal lines on walls
Different textures change the space well. If you want to easily stretch the room, then decorate the walls with horizontal lines. If, on the contrary, you need to reduce something, then frame it with vertical lines.
Floating table in the interior
If you wish, you can decorate your kitchen with so-called floating furniture. To do this, you will only need to buy a table whose legs will be made of either transparent plastic or glass.
Hidden doors
Also, if you wish, you can decorate your home with an invisible door. To achieve a similar effect, you will have to install a door with hidden hinges, and then decorate it in the same color as the walls.
Optical Illusion: Dress Form
Optical illusion: color
As you probably already understood, visual deception can help a person make the world around him more organic, and this applies not only to the interior. If you need to correct your figure, you can try to do this using optical illusions. All that will be required of you is to choose the right color and shape of your outfits.
Surrealism in painting
Two-faced picture
Optical illusions are very popular among artists. They help them make their paintings deeper and more interesting not only visually, but also semantically. As a rule, for this they use so-called two-faced pictures.
Most often, in this way they try to disguise the caricature. Surrealist artists use a similar technique to create drawings with a triple image, thereby trying to give their masterpiece a deeper meaning. You can see examples of such paintings a little higher.
Tenderness and strength in one picture
Salvador Dali is considered the most famous surrealist in the world. He always painted images in his paintings that made a person far from art think. This is probably why even now people look at his masterpieces with great pleasure and try to understand what the great artist was thinking about when he painted them.
Optical illusions are nothing more than an optical illusion of our brain. After all, when we look at a picture, our eye sees one thing, but the brain begins to protest and claim that this is not at all what it is. So it turns out that illusions are created by our mind, which begins to analyze the color, the position of the light source, the location of edges or corners, etc. Thanks to this, the correction of visual images occurs.
Be careful! Some illusions may cause tears, headache and disorientation in space.
Invisible chair. 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.
Volumetric Rubik's Cube. The drawing looks so realistic that there is no doubt that this is a real object. Twisting the piece of paper, it becomes obvious that this is just a deliberately distorted image.
This is not an animated gif. This is an ordinary picture, all elements of which are absolutely motionless. It is your perception that is playing with you. Hold your gaze for a few seconds at one point, and the picture will stop moving.
Look at the cross in the center. Peripheral vision turns beautiful faces into monsters.
Flying cube. What looks like a real cube floating in the air is actually a drawing on a stick.
Eye? A shot from photographer Liamm, who was filming a foam sink but soon realized it was an eye staring back at him.
Which direction does the wheel spin?
Hypnosis. 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.
Four circles. Be careful! This optical illusion can cause headaches lasting up to two hours.
Ordering squares. The four white lines appear to be moving randomly. But once you put images of squares on them, everything becomes quite natural.
The birth of animation. Animated images, overlaying a grid of black parallel lines. Before our eyes, static objects begin to move.
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.
Classical 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 shining example- impossible Penrose triangle.
It is in the form of a so-called “endless staircase”.
And also “The Impossible Elephant” by Roger Shepard.
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.
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.
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.
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.
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 as white and gold noticed the brightly lit background and decided that the dress was in the shadows, which means the 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 a 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.
Optical illusion is a hoax human vision. Observations of some images leave visual illusions in our minds.
Optical illusion is the unreliable perception of certain visual information. A person, looking at an illusion, incorrectly estimates its size or shape, creating a deceptive image in his mind.
The reason for erroneous perception is the structural feature of our visual organ. Physiology and psychology of vision allow us to make the wrong final result and instead round shapes, a person is able to see square ones, and large pictures will seem small.
Illusion - error of visual perception
Optical illusion can be divided into several main types:
The human brain can react deceptively to some images. It seems that the image moves or even changes color only due to the fact that the brain perceives the visible light of some pictures.
One of the most popular are the so-called moving pictures. Secret of this type lies in color and contrast perception.
moving picture It is enough to look at the center of this picture for a few seconds, then look away to one of the sides of the salad frame of the image, and the picture will literally “float”.
moving illusion "wall" This illusion can be classified into two types: “curvature of shape” and “moving illusion”. Firstly, the uneven placement of the cubes allows us to conclude that the lines are crooked.
However, they are absolutely smooth. Secondly, if you move the picture up and down using the slider on your monitor on the right, you can see how the cubes move and run.
moving illusion Thanks to the textured image, it seems that the squares in the center of the picture are moving.
an illusion that moves Thanks to the contrasting image of the round disks, it seems that they are moving in different directions: clockwise and counterclockwise.
the illusion moves Patterns in the picture different sizes and stand out with bright contrasting colors. This is why the lines and curves appear to be moving.
While observing illusions, the child exercises his logical thinking and develops his brain.
The most popular illusions for children:
animal shifter This illusion helps the child understand which animal is shown in the picture: a cat or a dog. The child analyzes all external features and remembers the characteristics; in addition, he tries to visually turn the image around, which trains his eye muscles.
volumetric illusion This illusion provides the child with the opportunity to see a three-dimensional image. In order to do this, you need to bring your face closer to the image, direct your gaze to the middle, diffuse your vision for five seconds and then quickly focus. This activity intensively trains the eye muscles and allows the child to develop vision.
mirror illusion Uniform prints located mirror to each other allow the baby to find common features of external parameters in different animals.
optical illusion This image allows you to develop abstract thinking: in the proposed picture you can see a simple branched tree. But if you read the contours correctly, the image of a newborn child will appear before your eyes.
Some images are called “pictures of hypnosis” because they are capable of misleading and a kind of trance, when a person diligently tries to understand the secret of the drawn objects and why they move.
hypnosis picture There is a belief that if you look for a long time at the center of a moving image, a person imagines himself plunging into a deep tunnel without a bottom or edge. It is this immersion that distracts him from other thoughts and his trance is comparable to hypnosis.
Black and white colors- are absolutely opposite. These are the most contrasting colors of all. Looking at such a picture, the human eye literally “doubts” which color to pay the main attention to, and that is why it turns out that the pictures “dance”, “float”, “move” and even appear in space.
The most popular black and white illusions:
parallel black and white lines The secret of the image is that the lines on the lines are drawn in different directions and that is why it seems that the lines are not at all parallel.
black and white illusions These images allow us to see two images in one picture. The drawing is based on the principle of contour and contrasts.
black and white illusion based on concentration In this illusion, for the effect you need to look for a long time at the red dot located in the image.
One minute will be enough. After this, your gaze is averted to the side and on any object you see what you previously observed only on the monitor.
This type of illusion allows a person to literally “break his brain.” This is because the picture displays the arrangement of objects in such a way that, firstly, they become three-dimensional on a plane, and secondly, sometimes they are too difficult to understand.
simple 3D illusion This picture makes it unclear to a person the location of objects: their sides and surfaces. Nevertheless, the drawing is perceived in volume.
complex 3D illusion picture More complex images require a person to peer into the depths of the picture for a long time. It is worth completely dissipating and splitting vision and after some time sharply restoring it.
A three-dimensional figure will appear on a completely flat picture (in in this case woman) with clear contours.
Optical illusions are errors that can occur in our vision. The causes of optical illusions are errors of perception.
While looking at a picture, inexplicable movements, disappearances and appearances may occur. All this is justified physiologically and psychological aspect visual perception.
optical illusion "black dot" The secret of the illusion is that when we notice a small black object in the center, we do not pay attention to our surroundings.
optical illusion "elephant" The unclear image of the contours allows us to see that the elephant has eight legs instead of four.
optical illusion "sun" Contrasting colors and unclear boundaries of the picture allow the image to literally vibrate the moment we look at it and remain immobilized when we turn our gaze to something else.
optical illusion “one picture - two images” Based on a mirror image with exact repetition of all forms.
optical illusion "dress" It is important to pay attention to the fact of lighting. look at the image in bright light and you will see a blue dress. Go into a dark room for half an hour and then look back at the picture - most likely you will see a golden dress.
As mentioned earlier, the secret of this illusion is hidden in the complete repetition of the lines of the drawing when it is mirrored. Of course, this can not be done in practice with every picture, but if you carefully choose the form, you will get quite an interesting result.
classic double picture "old or young woman?" Looking at this image, you need to decide for yourself: “What do you see first?” Of the possible options, you will see a young girl, turned in profile with a feather in her headdress, or an old woman with a long chin and a large nose.
modern double image Among the more modern versions of the double image, we can distinguish paintings that simultaneously depict two separate drawings. In such cases, the features of one image are read in different lines.
If an adult is quite calm about the brain’s distortion of some real things, then an illusion for children is something magical and inexplicable. The visual process for most representatives of humanity is a completely common phenomenon. People see what is happening around them, but at the same time they do not think at all about how the image is transmitted. This is very difficult process, in which the eyes, namely the retina and the brain, play a huge role. It is interesting that a person can often catch himself thinking that he sees in one object similarities with another object. This happens thanks to complex operations in the brain, which can produce various information, depending on a person’s life experience and previously seen things. A special category includes gifted children who perceive the surrounding reality somewhat differently.
Optical illusions play a special place in human visual perception. There are a huge number of them in our world. Some of them are very interesting and their appearance will take your breath away. Such visual experiments will be very useful in the case of children. Optical illusions are used not only for entertainment, but also for scientific purposes. For example, they are very important for psychologists, as they can help determine the level of human development.
The world of optical illusions has not been studied well enough in our time. Many scientists have spent a lot of time and effort to determine what exactly caused the optical illusion. However, most optical and geometric illusions have never received a worthy explanation.
However, it is very entertaining topic. Illusions and reality can be astoundingly different. For example, how amazing it is to look at a sheet of paper with drawn elements and see their movement! At the same time, the brain can understand that the picture is completely static, but the eyes see everything differently. These are fascinating riddles of the eyes and brain that children and their parents can solve.
It is difficult to imagine that a person would stop perceiving the world through vision. People are used to relying on their eyes, so they trust them completely. But the visual process cannot be called ideal. And it's not just about those people who suffer various diseases eyes, but also about those who have never had vision problems.
Given that the visual process is imperfect, the eyes can be easily outsmarted. This is exactly what happens when looking at optical illusions. This topic has been studied for a very long time. There is a whole list of illusions that can be called classic.
One of the most studied and interesting topics is the Müller-Lyer illusion. It is based on the fact that a person sees two identical lines with different endings and perceives them as segments of different lengths. The illusion occurs when looking at an image of a cube drawn in perspective. Such optical phenomena are considered geometric vision errors. But there are also more interesting ones that children will definitely like. At this age, moving illusions attract the most attention.
But these are all relatively modern options. But the possibilities of deceiving the human eye were noticed by Aristotle. It was he who in 350 BC. e. noted that human feelings You can trust them, but they are very easy to deceive. Classic illusions can be seen not only on paper, but also in everyday life. For example, anyone can observe how reality merges with optical illusion. If you look from a distance at the falling water in a waterfall for a long time, and then suddenly turn your gaze to the mountain, you get the feeling that the rocks are moving in the opposite direction.
There is a certain explanation for this. Scientists believe that the human brain gets used to one picture with constant movement. Therefore, when you have to look at static objects, the aftereffect of movement occurs.
The waterfall illusion is far from the only one that can be used to entertain parents and children. In nature and during walks you can see many other optical illusions.
Similar phenomena have been known for a very long time. But for a long time people did not pay enough attention to optical illusions. Their thorough study and description began a little over 100 years ago. Nowadays, optical illusion is the object of study by psychologists, artists, architects and designers. There is even a special set visual illusions, allowing us to determine mental capacity person. Thus, gifted children are identified at an early stage. They require a special approach, so the sooner this feature of the child is determined, the easier it will be to pass educational process and teaching kids who are gifted.
But now optical illusions are widely used in various aspects of life. And there was a time when they were mistaken for vision problems. But in fact, illusions are associated not only with the visual, but also with the brain process. In this way, information about the surrounding world is deciphered. But it is not always correct, since some aspects influence the creation of an inadequate and distorted perception of objects, their size, distance and condition.
Optical illusions differ in certain parameters. Most often they depend on the color of the picture, size and perspective. Based on this, you can create optical illusions and view them with your child.
This type of optical illusion depends on the science of geometry. These illusions are familiar to humans and can be easily traced in Everyday life. The human brain can easily distort its perception of the size, length, and depth of an object being viewed.
To show a child an optical-geometric illusion, it is enough to pay attention to the usual railway. The rails at foot level will be located far from each other, but when a person looks forward, you can see that they are getting closer, and at the point of the horizon they completely connect. It is a perspective that ends at one point. In reality the rails will be consistently spaced evenly apart, but they appear to taper.
When viewing a railway track, you can observe how the parallelism of the lines is lost in perspective. The further you look at the road, the more difficult it will be to determine the distance.
A similar phenomenon was noticed and described by psychologist Mario Ponzo. He created the concept of the usual reduction in the size of an object as it moves away 100 years ago. Thus, the railroad illusion is a stereotype for the human visual process.
Among geometric illusions, those based on describing the depth of an object are very popular. Optical illusion occurs due to the fact that the right and left eyes see different images. When using depth, disparity is applied. Considering that there will be a different arrangement of points on the retina of each eye, the object is visually perceived as concave or convex.
In order to explain and show this illusion to a child, you can go to a 3D movie or simply take any picture where there is a similar image. The eye sees a three-dimensional image, although in reality the hands are holding an ordinary sheet of paper without any protrusions.
One of the most important functions What the human eye can do is color detection. The ability to distinguish shades depends on lighting. Many optical illusions work based on color and shadows. With a lack of light, the receptivity of the eye “flows” from one element to another, having different shades. These are features of the human retina.
Some time ago, pictures began to appear on the World Wide Web in which visual deception was clearly visible. The images show that the item is one color, although in reality the shade is different.
Some time ago, the Internet was blown up by an image of a blue strawberry that most people thought was red. And this is surprising, because if you break down the image into shades, then there is no hint of red or pink color there was no. Such an optical illusion is based on the life experience that a person has. If the brain has already seen strawberries before and they were always red, then the information from the picture will be perceived accordingly.
An interesting type of optical illusion are those based on contours. People can see different objects in the same picture. There are special optical illusions that can have several interpretations due to their special contour.
Based on the fact that people can perceive information in their own way, depending on their life experience, level of intelligence and other factors, a special psychological test. It is called "Rorschach Pictures". These are images with contour patterns that at first glance look more like spots. Experts note that when looking at these pictures, people perceive them the same way with their eyes, but the brain interprets the information depending on the person’s personal characteristics. In this way, a specialist can find out more information about his patient, his psychological state, knowledge and life experience.
You can use optical illusion in various aspects of life. Optical illusions are widely used not only in psychology, but also in creativity, and most often by artists, designers and architects. In addition, you can create a whole entertainment program for children. There are many visual illusions that a child will enjoy. You can play them not only on the street, looking at the railway or mountains with waterfalls, but also at home.
Children are most attracted to eye illusions called shapeshifters. This is a trick that consists of one image, but the brain can interpret it in different ways. It all depends on which way to turn the sheet with the picture.
There are several popular images in the shapeshifting style. Many people know pictures with a princess and an old lady, a duck and a hare. There is no perspective in these images, and the illusion is based on perceptual readiness. To see the differences, just turn the sheet.
Similar optical illusions can be observed in reality. For example, if parents and a child look at the clouds floating across the sky, then on the one hand it may seem similar to one object, and on the other - like something completely different.
A very interesting optical illusion can be observed in the Ames room. This is a three-dimensional optical illusion that was created in a specially equipped room. The special design of the room gives the impression that the objects are of different sizes, but in fact, these objects will be exactly the same. The reason for this effect lies in the design of the Ames room. A similar solution occurred to the master in 46 of the last century. And the room is still very popular and is considered one of the best optical illusions.
If you look at the room, it seems that there are ordinary parallel walls that are built perpendicular to the floor and ceiling. But in reality, Ames's room is shaped like a trapezoid. The far wall is located differently than in standard rooms. To achieve greater efficiency, tiles designed in the form of chessboard. All together this creates a simply wonderful result. If two people enter Ames’s room and then stand in different corners, one will seem like a giant, and the other will be at least half the size.
It is very interesting to spend time in such a room. Here you can not only stand, but also move, which creates the illusion of a person quickly increasing in size. At the same time, experts say that to create the effect that is used in the Ames room, it is not at all necessary to equip the entire room. A lot depends on the location of the horizon. This optical illusion has long been noticed by decorators, so the effect is often used to create special effects when it is necessary for one person to be significantly taller than another.
It will be interesting for the child to see images with optical illusion, where the illusion of movement plays a major role. The thing is that if the pictures are absolutely static, then the brain perceives everything differently. At the same time, focusing your gaze on one element, you can notice that the dynamism disappears here.
Distortion of perception occurs due to the arrangement of elements in the picture and the distribution of colors. In addition, circular arrangement, vectorization and irregular shapes are often used here.
There are many similar optical illusions. By looking at them with your child, you can conduct experiments. If you alternately approach and move away from the image, the effect of dynamics on a flat sheet is greatly enhanced.
Somewhat similar in principle of operation are optical tracking illusions. We are talking about paintings that constantly look at a person, no matter where he is. This is a very interesting visual effect that often occurs in reality. The illusion of tracking is clearly visible in many portrait photographs, posters and paintings. The most popular representative of this category is the Mona Lisa by Leonardo da Vinci.
What's interesting is that the illusion of tracking for a long time considered a mystical effect. But, as it turned out, there is nothing unusual in this, which has been proven by scientists. Experts have learned to create the effect of watching eyes. This result can be achieved by every artist who follows certain rules.
A prerequisite is a portrait, that is, the image of the face must be large. In this case, the object must look directly at the artist. Emotions, or rather the lack thereof, are very important. If there is an indifferent person in the painting or photograph, this will enhance the illusion of tracking. Large canvases make a greater impression. Moreover, proper lighting and shade must be provided. If everything is done as expected, the effect of a three-dimensional image can be created. This creates a feeling of volume, which is why human brain begins to think that the eyes in the picture are constantly moving.
Some parents are wary of images that cause visual deception. But in fact, there are a lot of advantages to such entertainment as studying optical illusions with a child.
Not all effects can be seen the first time. Therefore, such pictures allow you to expand your perception of reality. Moreover, when viewing optical illusions, the eyes have to adapt to new images. This has a beneficial effect on the quality of vision in the child.
Optical illusions help you focus and concentrate on one process. These skills are useful at any age, but it is better to develop them from childhood. Experts recommend this type of activity for children and teenagers, as it allows them to develop imagination and spatial thinking. With regular viewing of optical illusions, you can turn an ordinary child into a creative genius. If a child plans to become an artist or architect, such classes will be useful to him.
It is worth noting that at any age, optical illusions arouse great interest, and for some even delight. And, despite the fact that in Latin “illusion” is translated as “deception,” it is a lie for the good, as it allows you to improve health, restore vision and develop Creative skills and attentiveness. Optical illusions for children are not just entertainment, but a useful pastime.
