Optical illusions are fun ways to improve kids’ cognitive abilities. An optical illusion image stimulates problem–solving skills and visual memory recall because the child will want to figure out how it works.
Optical illusions are caused when the brain interprets the object that the eyes see differently. The rods and cones are the optic receptors in the eyes. What the eyes see is transformed into the brain as electric impulses which the brain interprets. The brain tries to make sense of what the eyes see. Optical illusions present something unusual to the brain.
Illusions aren’t hallucinations. An optical illusion is seeing an object differently, whereas a hallucination is viewing an object that isn’t there.
The three types of optical illusions are literal, cognitive, and physiological. A literal illusion is seeing an image as something different than the image or images displayed. Although the images exist, what you see is based on your perception. A cognitive illusion is how the brain interprets something new that wasn’t explained. It reveals how the mind relates one object to another and what it’s subconsciously thinking. With a physiological illusion, the brain is confused by what the eye sees with light, color, size, movement, and dimension. The brain rectifies its confusion and then interprets what the eye saw, which isn’t physiologically possible.
The first known optical illusion created was about 2500 years ago on the island of Lesbos in Greece. The coin shows the two animals facing each other forms a wolf face facing forward.
Confetti Illusion
How many different colored circles do you see?
Answer
The circles are all the same color.
In July 2018, Dr. Novick, University of Texas professor, shared the Confetti illusion on Twitter. The optical illusion is an example of a Munker illusion where surrounding horizontal stripes in different colors influence the color perception of objects.

Hermann Grid Optical Illusion
Take a look at this illustration. How many black dots do you see?
Answer
No, this isn’t an animated GIF. There are no black dots. There are only black blocks and white space. The high contrast presents the eyes the illusion of grey or black dots at the intersections. Focus on the dot, and you’ll see the dots are white.
Animal Optical Illusion
Take a look at this sketch. How many animals do you see?
Answer
Two: a rabbit is looking to the right, and the duck is looking to the left. The duck’s beak is the rabbit’s ears.
The illusion appeared for the first time in a German magazine in 1892.
According to American psychologist Joseph Jastrow, the quicker you switch between the two animals, the more creative you are.
Elephant Leg Illusion
How many legs does this unusual elephant have?
Answer
It is a literal optical illusion. The brain perceives two different images in one. The artist drew one leg with a foot, four legs without feet and four feet without legs.
Kanizsa Triangle Optical Illusion
What patterns do you see? Do you see triangles? Discs?
Answer
Most people see a white triangle facing upwards and the outline of a black triangle downwards with three black discs. The symmetrical image is three black discs missing a triangular part and three pairs of lines. There is no large white triangle in the middle of the page – though I’m sure you see one!
Italian psychologist Gaetano Kanizsa described the illusion.
It explains the law of closure where objects grouped seem to be part of a whole. The brain ignores the gaps and perceives the contour lines as a whole.
Color Gradient Optical Illusion
Which side of the inner rectangle is the darkest?
Answer
The bar is the same color. The optical illusion is lightness perception. The eyes perceive colors differently depending on the color in the background or foreground.
Muller-Lyer Optical Illusion
Observe the two lines with arrowheads on each end. Which line is the longest?
Answer
The lines are the same length. For most people, the line with the fins facing outward seems longer than the line with the spines facing inward. The illusion was created by a German psychologist F.C. Muller Lyar in 1889. Opinions differ on how the perceptual illusion works, whether it has to do with depth, size, or length
Wife or Mother-in-Law Illusion
Who do you see, the wife or the mother-in-law?
Answer
The mother-in-law’s nose is the wife’s jawline.
The wife’s necklace is the mother-in-law’s mouth.
British cartoonist William Ely Hill created this brainteaser in 1915. It’s almost impossible to see the wife and the mother-in-law’s faces at the same time. According to Australian researchers, people tend to see the faces of people of similar ages. Therefore, younger people see the wife and older people see the face of the mother-in-law.
If you can’t see the mother-in-law, focus on the wife’s right ear. If you can’t see the wife, focus on the mother-in-laws left eyelash.

Impossible Trident Illusion
How many prongs are in the fork?
Answer
The impossible fork, also known as blivet, shows an object that can’t exist. At the one end, there are two rectangular prongs, and at the other end, it looks like three cylindrical prongs. It was discovered in 1964 when D. H. Shuster noticed an “ambiguous figure of a new kind” in the advertising section of an aviation journal.
Twelve Black Dots Illusion
How many dots do you see at the same time?
Answer
Most people can’t see all 12 dots simultaneously. The dots in the middle of their vision stay constant. Peripheral vision isn’t as clear. The brain guesses that the continuous pattern of white lines on a grey background continues peripherally and misses the black dots at certain intersections.
Although posted on Twitter and Facebook, the variation of the Hermann Grid was first published in 2000 in a scientific journal SAGE.
Pink or Grey Sneaker Illusion
What color is the sneaker?
Answer
The shoe is pink and white but many people see it as grey. The brain decides a color by considering the colors surrounding the object. Most people probably see the shoe as grey and teal because the brain takes into consideration the colors of the hand holding the shoe.
Those who brains see a blue background depicts that the shoe is pink and white.
Zöllner Optical Illusion
Observe the diagonal lines in the image. Are the lines parallel?
Answer
German astrophysicist Johann K. F. Zöllner discovered this effect in 1760. The parallel diagonal lines intersect with short horizontal and vertical bars. It creates an image where the parallel lines seem to join and separate from each other. Scholars aren’t sure why this happens. It could be the way the brain adjusts angles, or it may be how it perceives depth. The illusion disappears when the colors in the image have equal values of red and green.
Lilac Chaser Illusion
Stare at the plus sign in the middle of the image for twenty seconds or so. What do you see happening in the circles around the +?
Answer
While staring at the + focal point, it seems as if the lilac dots move in a circle that changes to a space moving around the circle of lilac dots.
After about 10-20 seconds a green dot appears that runs around the ring.
Vision expert Jeremy Hinton created the lilac disc in 2005. Apparent movement is when a person sees something in one spot and then in another place, and the brain perceives it as a movement. The green color is the afterimage. When a person stares at a color for a while and looks away, they may see the same color, which is the positive afterimage. Alternatively, they see the negative afterimage, which is the opposing color of the image.
Poggendorff optical Illusion
Observe the three lines on image. Which line does the black line connect to?
Answer
Although it seems as if the black line links with the blue line, it matches the red line. The image is distorted by the brain‘s perception of diagonal lines interacting with horizontal and vertical edges.
In 1860, German physicist Poggendorff received a letter from Johann Zöllner describing the illusion created by the fabric design.
Poggendorff noticed the misalignment of the diagonal lines in the fabric design. The illusion is caused when a thin diagonal line is placed behind wider stripes at an angle.
Two Women Illusion
What do you notice about the women in the picture? Which one is shorter than the other?
Answer
The women are the same size – although they seem to be different sizes. The room appears square but distorts into a trapezoidal shape. The woman at the left is standing closer than the woman to the right, but it seems visually as if they are in the same depth of field. Hence, the one looks taller than the other.
Image Source
Ponzo Optical Illusion
Which yellow horizontal line is the longest?
Answer
The two yellow lines are the same length. The upper line seems longer because of the parallel lines converging in the distance. The perspective hypothesis explains the illusion.
In three dimensions an object in the distance needs to be larger to appear the same size as a closer object.
Ebbinghaus Optical Illusion
Which of the two orange discs is smaller – the left one or the right one?
Answer
The orange discs are the same size. The illusion was discovered by German psychologist Hermann Ebbinghaus but was popularized in 1901 when published in a textbook by Edward Titchener. It is a size contrast illusion. The surrounding blue disc sizes influence the perception of the orange disc sizes.
Image Source
Hering Optical Illusion
Which way do the vertical lines bend?
Answer
The lines are straight. It seems as if the lines are bending outward due to the false impression of depth created by the radial background. German physiologist Ewald Hering discovered this geometric optical illusion in 1861.
Moon Illusion
Is the moon bigger when seen at the horizon than in the sky?
Answer
It seems as if the moon is more prominent, surrounded by scenery than high in the sky.
The reason why the moon seems bigger closer to the horizon is due to depth perception. The trees, building, and surrounding images are the depth cues. In the sky, there aren’t any depth cues to relate to the moon. The color of the moon, atmospheric perspective, and visual factors influence how the moon’s size is perceived.
Stroop Effect Illusion
Which is faster to read the words or ignoring the words but reading the color of each word?
Answer
It’s faster to read the text. J. Ridley Stroop discovered this marvel in 1930. When reading the color instead of the word, the brain receives conflicting messages. The Speed of Processing theory explains the interference because the text reads faster than words. According to the Selective Attention Theory, naming the color requires more attention than reading the text.
Strawberry Illusion
What color are the strawberries?
Answer
The strawberries aren’t red.
There are no red pixels in the image; only cyan pixels. Japanese Psychology professor Akiyoshi Kitaoka published the picture on Twitter. The National Eye Institute explains that the brain ‘corrects’ the color when it perceives it in a different color.
Troxler’s Fading Circle Illusion
What happens to the circle when you stare at the dot in center of the ring for about 20 seconds?
Answer
The circle fades and disappears. In 1804, Swiss physician and philosopher Ignaz Troxler used the illusion to demonstrate how efficient the brain functions. The brain filters out unimportant and non-threatening information to focus on what’s important. When staring at the dot, the brain doesn’t receive any new information, and the circle fades into the white background as the brain disposes of unimportant data.
Image Source
Checkerboard Cylinder Shadow Optical Illusion
Take a look at the checkerboard pattern.
What color is square A? Square B?
Answer
The two checker squares A and B are the same color. The illusion is created by the way the brain interprets contrasts and shadow. The brain perceives a light source from the right that casts a shadow on the board. Therefore, square A seems darker than square B, but both are light grey. The checker shadow illusion was published in 1995 by MIT professor of Vision Science, Edwards Adelson.
Question-Answer Optical Illusion
What word(s) do you see in the painting?
Answer
Question and Answer are the two words. John Langdon’s painting is an example of an intentional perceptional illusion. It is a type of steganography where words are hidden in larger scenes. A person tends to perceive the larger picture and often misses the smaller details.
Image Source
Coffer Optical Illusion
How many circles do you see? How many rectangles?
Answer
There are 16 circles.
Vision scientist Anthony Norcia form The Infant Laboratory at Smith-Kettlewell was one of the ten finalists in 2016 Best Illusion of the Year Contest with the Coffer Illusion. The brain identifies grouped objects to form edges and contours. Segmentation cues contradict the interpretation of a series of rectangular coffers with closed boundaries. The horizontal lines can represent a circle or the intersection of rectangles.

11 Optical illusions for kids
Optical Illusions for kids play with the way an object appears, through the use of colour, light, images and patterns to manipulate what our brains are perceiving.
why do we see them?
Our visual system has limits in tackling all the information our eyes take in. So our minds take shortcuts and our brain constantly chooses the most likely interpretation of what we see.
Check out some interesting optical illusions for kids below and let us know which one you liked best.
HOOT HOOT
They say that some of the greatest moments in life are unplanned.
What we see is the face of a mysterious owl staring back from the cup of a mans morning coffee.
What it really is? This optical illusion was created, as a result of two Hula Hoops (potato snacks) being dropped into the mug.

MOVING SQUARES
Scroll this picture up and down and the squares will move.
How does this happen? One theory is that when you move your head back and forth, the alternating dark and light patterns can seem to cause the perception of movement.

My Wife and My Mother-in-Law
The illusion is considered to be one of the most famous optical illusions in the world (dating back to 1915).
Some people see a young lady with her head turned towards the background while others see an elderly woman’s side profile.
What do you see? It’s almost impossible to see both at the same time!
Australian researchers asked 393 participants aged 18 to 68 to tell them who they saw in the optical illusion. The results, published in the August 2018 issue of Scientific Reports showed that the youngest set of people tended to see the wife first, while the oldest set of participants tended to see the mother-in-law first.

Lightbulb magic
All you need to do is stare closely at this light bulb for 25 seconds.
Then immediately stare at a white wall or sheet of paper.
What do you see?
You should see a glowing light bulb!
SOULMATES
When you look at this image, what colour are the left and right hearts?
Well, The hearts are actually the same colour, it is the lines over them that are of different colours.
Image source.
SPINNING DANCER
Is the lady spinning clockwise or counter-clockwise? You may even see the figure suddenly spin in the opposite direction if you look closely.
Did you know this figurine is used to determine whether or not people are right-brain (creative) or left-brain (logical) dominant?
Viewers are told that if they view the dancer as standing on her left leg and spinning clockwise, then they are right-brain dominant (creative), and if they see the reverse (the dancer standing on her right leg and spinning counter-clockwise), then they are left-brain dominant (logical).
Read more.
So how does it work? It has to do with our visual cues and bistable perception. This occurs when visual cues are ambiguous and our brain tries to make sense of it.
A path between rice fields
A work by Japanese artist Makoto Aida titled AZEMICHI.
This photograph shows a young Japanese schoolgirl standing between two rice fields.
The painting creates an optical illusion with the little girl’s parted hairline as it merges with the divide between the rice fields.
Read more.
Are you colourblind?
What number do you see in the circle?
Answer: You should be able to see the number 74, but people with red-green colour blindness see a 21. Those with total colour blindness see nothing.

Direction confusion
Are both arrows pointing the same direction on the paper behind the glass?
What is happening? This image showcases the effects of refraction (the bending of light).

DANCING DOG
Timing is everything.
Tell that to the man, busy reading his morning news.
I guess, “Dreams”, really do come true, doesn’t it?
Image source.
SPOT THE PREDATOR
In this image try finding the predator.
Then scroll down to the coloured version of the same image, and try again.
Why is it so easy this time? The reason is that the second image shows the surfaces according to the quality of light they reflect (not just their intensity), while in the first image you are only seeing the surfaces according to the amount of light they reflect.
In other words, your brain has a lot more information for making its decisions.

😮 30 Cool Optical Illusions: Brain Explosion | Interesting facts
We are used 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 world perception serve as a pretext for the emergence of optical illusions. There are a lot of them, but we tried to collect for you the most interesting, crazy and incredible of them. nine0003
Top Stunning Optical Illusions
Impossible Figures
At one time this genre of graphics was so widespread that it even got its own name - impossibilism. Each of these figures seems quite real on paper, but simply cannot exist in the physical world.
Impossible Trident
Classic Impossible Trident
Classic blevet is perhaps the brightest representative of optical drawings from the "impossible figures" category. No matter how hard you try, you will not be able to determine where the middle prong originates. nine0003
Another striking example is the impossible Penrose triangle.
Impossible triangle
It is also in the form of the so-called "endless staircase".
Infinite Penrose Stairs
And Roger Shepard's "impossible elephant".
Shepard's Impossible Elephant
Ames' Room
Adelbert Ames Jr. has been interested in optical illusions since early childhood. After becoming an ophthalmologist, he did not stop his research on depth perception, which resulted in the famous Ames Room. nine0003
Ames Room Optical Illusion
How the Ames Room works
In a nutshell, the effect of the Ames Room can be expressed as follows: it seems that two people, a dwarf and a giant, are standing in the left and right corners of its back wall. Of course, this is an optical trick, and in fact these people are of quite ordinary height. In reality, the room has an elongated trapezoidal shape, but because of the false perspective, it seems to us rectangular.
The left corner is farther away from the visitors' view than the right corner, and therefore the person standing there seems so small. nine0003
The principle of the Ames room
Illusions of movement
This category of optical tricks is of the 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 goes astray, the retina captures the image intermittently, spasmodically, and the brain activates the areas of the cortex responsible for detecting movement.
Floating star
It's hard to believe that this picture is not an animated gif-format, but an ordinary optical illusion. The drawing was created by Japanese artist Kaya Nao in 2012. A pronounced illusion of movement is achieved due to the opposite direction of the patterns in the center and along the edges.
"Floating Star" Kaya Nao
There are quite a few such illusions of movement, that is, static images that seem to move. For example, the famous spinning circle. nine0003
A spinning circle
Or yellow arrows on a pink background: when you look closely, they seem to sway back and forth.
Moving hands
Warning, this image may cause eye pain or dizziness in people with weak vestibular apparatus.
Rays from the center
Honestly, this is a regular picture, not a gif! Psychedelic spirals seem to drag somewhere into the universe full of oddities and wonders.
Striped spirals
Flipped illusions
The most numerous and fun genre of drawings-illusions is based on changing the direction of looking at a graphic object. The simplest upside-down drawings just need to be rotated 180 or 90 degrees.
Nurse or old woman
Two classic flip-flop illusions: nurse/old woman and beauty/ugly.
Beauty or ugly
A more artistic picture with a twist - when rotated 90 degrees, the frog turns into a horse. nine0003
Horse or frog
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."
The most famous optical illusions: the old woman and vase profiles
Old people / Mexicans
An elderly couple or Mexicans singing to the guitar? Most see old people first, and only then do their eyebrows turn into a sombrero, and their eyes into faces. The authorship belongs to the Mexican artist Octavio Ocampo, who created many pictures-illusions of a similar nature.
nine0003
Old men/Mexicans Octavio Ocampo
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 brain, not yet familiar with sexual relationships and their symbols, simply does not isolate two lovers in this composition. Older people, on the contrary, first see a couple, and only then dolphins.
Dolphins or lovers - another interesting optical illusion
The list of such dual pictures is endless:
The well-known Eskimo Indian
In the picture above, most people first see the face of the Indian, and only then look to the left and distinguish the silhouette in a fur coat. The image below is usually interpreted by everyone as a black cat, and only then does a mouse appear in its contours.
Cat or mouse?
A very simple upside-down picture - you can easily make something similar with your own hands.
nine0003
Snow White or Sherlock Holmes?
Illusions of color and contrast
Alas, the human eye is imperfect, and in our assessments of what we see (without noticing it) we often rely on the color environment and the brightness of the background of the object. This leads to very interesting optical illusions.
Gray squares
Optical illusions of colors are one of the most popular types of optical illusion. Yes, yes, squares A and B are painted in the same color.
Squares A and B are actually the same color
This trick is possible due to the way our brains work. A shadow without sharp borders falls on square B. Thanks to the darker "environment" and smooth shadow gradient, it seems to be much lighter than square A.
And here is the proof
Green Spiral
There are only three colors in this photo: pink, orange and green.
The blue color here is just an optical illusion
Don't believe me? Here's what happens when you replace pink and orange with black. nine0003
Without a distracting background, you can see that the spiral is completely green
Is the dress white and gold or blue and black?
However, illusions based on the perception of color are not uncommon. Take, for example, the white and gold or black and blue dress that conquered the Internet in 2015. What color was this mysterious dress, and why did different people perceive it differently?
The explanation of the dress phenomenon is very simple: as in the case of gray squares, it all depends on the imperfect chromatic adaptation of our organs of vision. As you know, the human retina consists of two types of receptors: rods and cones. Rods capture light better, while cones capture color. Each person has a different ratio of cones and rods, so the definition of the color and shape of an object is slightly different depending on the dominance of one or another type of receptor.
nine0003
Those who saw the white and gold dress noticed the brightly lit background and decided that the dress was in shadow, which means that the white color should be darker than usual. If the dress seemed blue-black to you, then your eye first of all paid attention to the main color of the dress, which in this photo really has a blue tint. Then your brain judged that the golden hue was black, brightened due to the rays of the sun directed at the dress and the poor quality of the photo. nine0003
Mysterious white and gold or black and blue dress
The actual dress was blue with black lace.
The dress turned out to be blue and black
And here is another photo that baffled millions of users who could not decide if it was a wall in front of them or a lake.
Wall or lake? (correct answer is a wall)
Disappearing circles
Optical illusions in the video
Ballerina
This crazy optical illusion is misleading: it is difficult to determine which leg of the figure is the supporting one and, as a result, to understand in which direction the ballerina is spinning.
Even if you succeeded, while watching the video, the supporting leg can “change” and the girl seems to start to rotate in the other direction. nine0003
The most popular optical illusion "Ballerina"
If you could easily fix the direction of the ballerina's movement, this indicates a rational, practical mindset. If the ballerina rotates in different directions, this means that you have a stormy, not always consistent imagination. Contrary to popular belief, this does not affect the dominance of the right or left hemisphere.
Monster Faces
If you look at the cross in the center for a long time, then peripheral vision will frighteningly distort the faces of celebrities. nine0003
Monster Face Illusion
Optical Illusions in Design
Illusions of the eye can be a spectacular tool for those who want to spice up their home. Very often, “impossible figures” are used in design.
It seemed that the impossible triangle was doomed to remain only an illusion on paper. But no, the design studio from Valencia has immortalized it in the form of a spectacular minimalist vase.
Impossible triangle vase
Bookshelf inspired by the impossible trident. Designed by Norwegian designer Bjorn Blikstad. nine0003
Blikstad's "impossible" bookshelf
Here's a bookcase inspired by one of the most famous optical illusions, Johann Zöllner's parallel lines. All shelves are parallel to each other - otherwise what would be the use of such a cabinet - but even for those who have long acquired such a rack, it is difficult to get rid of the impression of slanted lines.
Inclined shelving
The creators of the Zellner rug were inspired by the same example.
Curvature of lines - optical illusion
Of interest to fans of unusual things is a chair designed by Chris Duffy.
It seems that it relies solely on the front legs. But if you dare to sit on it, you will realize that the shadow cast by the chair is its main support.

Illusion is an optical illusion.
Types of optical illusion:
optical illusion based on color perception;
optical illusion based on contrast;
warp illusions;
optical illusion of depth perception;
optical illusion of size perception;
contour optical illusion;
optical illusion "changeling";
Ames room;
moving optical illusions. nine0201 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 bigger than the bottom one?
In fact, this is an optical illusion: these two balls are absolutely equal.
You can use the ruler to check. By creating the effect of a receding corridor, the artist managed to deceive our vision: the upper 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 a close distance, you see the brilliant physicist A.Einstein.
Now try to move a few meters away, and ... a miracle, in the picture M. Monroe. Here everything seems to be done without optical illusion. But how?! No one painted on mustaches, eyes, hair. It’s just that from afar, vision does not perceive any little things, but it puts more emphasis on large details.
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. nine0003
Look at the cross in the center
Peripheral vision turns pretty faces into monsters.
Ferris wheel
In which direction does the wheel spin?
Hypnosis
Stare without blinking at the middle of the image for 20 seconds, and then look at someone's face or just a wall.
WINDOW SIDE ILLUSION
Which side of the building is the window on? On the left or maybe on the right?
Once again our vision was deceived. How did this become possible? It is very simple: the upper part of the window is shown as a window located on the right side of the building (we look, as it were, from below), and the lower part is on the left (we look from above). And vision perceives the middle, as consciousness considers it necessary. That's all deception. nine0003
Bar illusion
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 lie on top of the other.
Cube and two identical cups
An 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 inspection, we can see that in fact the cube is drawn, and the cups are exactly the same size. A similar effect is noticed only at a certain angle. nine0003
Cafe wall illusion
Look carefully 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. That's 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 it looks like the tower on the right is leaning more than the one on the left, but the two pictures are actually the same. The reason lies in the fact that the visual system considers two images as part of a single scene.
Therefore, it seems to us that both photographs are not symmetrical. nine0003
ILLUSION OF WAVY LINES
There is no doubt that the depicted lines are wavy.
Remember the name of the section - optical illusion. You're right, they are straight, parallel lines. And it's a twisting illusion.
Ship or arch?
This illusion is a true work of art. The picture was painted by Rob Gonsalves, a Canadian artist, a representative of the magical realism genre. Depending on where you look, you can either see the arch of a long bridge or the sail of a ship. nine0003
ILLUSION - GRAFFITI "LADDER"
Now you can relax and not think that there will be another optical illusion. Let's admire the imagination of the artist.
Such a graffiti was made by a miracle artist in the metro to the surprise of all passers-by.
NEZELLE EFFECT
Look at the picture and say in which part the red lines are brighter and more contrasting.
On the right, right?
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. nine0003
COLOR CHANGE ILLUSION
Does the color of the horizontal gray line change into a rectangle?
The horizontal line in the picture does not change throughout and remains the same gray. Can't believe it, right? This is an optical illusion. To verify this, cover the rectangle surrounding it with a piece of paper.
REDUCING SUN ILLUSION
This stunning photo of the sun was taken by the American space agency NASA. It shows two sunspots pointing directly at the Earth. nine0003
Something else is much more interesting. If you look around the edge of the Sun, you will see how it shrinks.
This is really GREAT - no cheating, good illusion!
ZOLNER'S ILLUSION
Can you see that the Christmas tree lines in the picture are parallel?
I don't see either. But they are parallel - check with a ruler. My vision was also deceived. This is the famous classical Zolner illusion, which has existed since the 19th century. Because of the "needles" on the lines, it seems to us that they are not parallel. nine0003
ILLUSION-JESUS CHRIST
Look at the picture for 30 seconds (or more may be needed), then look at a bright, even 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? The human eye contains cells called rods and cones. The cones are responsible for transmitting a color image to the human brain under good illumination, and the rods help a person see in the dark and are responsible for transmitting a low-definition black and white image.
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 the 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." nine0003
ILLUSION. THREE SQUARE
Sit closer and look at the picture. Do you see that the sides of all three squares are crooked?
I also see crooked lines, despite the fact that the sides of all three squares are perfectly even. When you move away from the monitor at some distance, everything falls into place - the square looks perfect. This is because the background makes our brain perceive lines as curves. This is an optical illusion. When the background merges and we do not see it clearly, the square appears to be even. nine0003
ILLUSION. BLACK FIGURES
What do you see in the picture?
This is a classic illusion.
Throwing a cursory glance, we see some incomprehensible 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 further complicates the task of the brain, because it is used to reading the word from left to right. nine0003
ILLUSION. OUCHI ILLUSION
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, it looks like the ball is moving 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 at a wall.
