+50 Amazing Optical Illusions for Children and Adults

The optical illusions They are visual perceptions that do not conform to the reality of the world in which we live.s but belong to perception. No.They tell you a lot about how we see and reconstruct everything that surrounds us from our perspective.

In this article you will find more than 50 illusions that will show you what your brain can deceive you. In fact, everything we see is a reconstruction that the mind makes of the reality that surrounds us.

Particularly, the human being interprets 80% of reality. That is, we only see 20% of the world as it is, the rest is interpreted. So it can be said that reality depends on how you interpret it.

Thanks to the effect of optical illusions, we realize that what our eyes see is not objective, but that the brain comes into play in the process of seeing. Thus, the brain interprets and reprocesses the information provided by our senses (smell, sight, hearing, taste and touch).

In the case of optical illusions, the sense involved is sight and distortion can be caused in relation to shape, dimension, color and perspective. Here we show you so you can see for yourself.

List of incredible optical illusions

crescent bat

It is not a video or a GIF, I assure you. This is an optical illusion in which a static image appears to be moving due to cognitive effects produced by interactive color contrasts and the position of the bat shape.

Try to fix your gaze on the bat for 10 seconds without blinking and you will literally hallucinate.

floating star

Oddly enough, the star above is static, it is not moving. Carefully arranged transitions between white, light-colored, black, and dark-colored regions trick neurons into responding as if they were seeing continuous movement in the same direction, rather than static edges.

Woman face

When people see this image, they don’t quite understand what is happening to the woman’s face. Is it a woman from the front or from the side? It actually combines features of a straight-facing face with a side-facing one.

fading image

Stare at the image for at least 30 seconds without moving your eyes and watch it gradually disappear. This is a variation of the Troxler effect which essentially says that if you fix your eyes on a certain point, stimuli near that point will gradually fade away.

monster illusion

This illusion can be found in many Psychology books. Although one appears larger than the other, the two monsters are in fact the same size. Your brain automatically adjusts images it perceives as distant to compensate for the fact that they are larger than they appear.

If you don’t think they are the same size, find a meter and measure them.


In an attempt to help raise awareness of the panda’s plight, Russian artist Ilja Klemencov created this optical illusion, which features a panda hidden behind zigzag black and white lines.

If you spot the panda you will notice that it is the famous logo of the World Wildlife Fund (WWF).

Where are the forest animals?

In this illusion you can find more than six animals.

Green Blue

There are several variations to this optical illusion, but the effect is the same. The “blue” and “green” backgrounds are in fact the same color.

You do not believe me? Isolate the two images in photoshop or with paint and you will see it.

Cat going up the stairs… or is he going down the stairs?

In this illusion it is not clear if the cat is going down the stairs or going up the stairs.

Five or seven?

Depending on which side you stand on, you will count 5 or 7.

The image of the old/young

Surely you too know this illusion. It is an image in which a young or an old woman can be seen indistinctly depending on the moment and the perception. You always tend to see one of the two before the other.


Created by web designer Nobuyuki Kayahara, some people see the figure rotating clockwise, while others see it rotating counterclockwise.

What do you think? Leave your opinion in the comments!

Parallel lines, curves or both?

Would you say these lines are parallel or curved? Well, despite the fact that your eyes tell you that they are curved, in reality they are parallel, totally straight. This illusion is known as the «cafeteria wall illusion.»

Ebbinghaus illusion

Which orange dot would you say is bigger? The one on the right or the one on the left? Well, although the one on the right seems bigger, both are the same.

This is because of the circles around you. The circles surrounding the left orange circle are larger, making the orange feel smaller. The effect is the opposite in the image on the right. As the surrounding circles are larger, the circle in the center is perceived as smaller.

Pac-man illusion

If you stare at the cross in the center for at least 15 seconds you will begin to see several green lights around the circle of magenta disks. After a few more seconds, the magenta disks will start to fade until all you see is a green disk going in a circle around the cross.

The Zoellner Illusion

This illusion was discovered by the German astrophysicist Johann Karl Friedrich Zöllner in 1860, hence its name. In the image you can see several small lines. Although they appear to lean, this is an optical illusion due to the diagonal lines. Actually small lines are straight.

motion illusions

These images are static, even though there appears to be movement. To check it, cover a part of the image and you will see how there is no movement.

The moving circles…

They don’t move, although they do for your brain. Colors and shadows are responsible for the sensation of movement.

the shadow illusion

Probably one of the most incredible illusions out there, it was published by Edward Adelson, a professor at MIT. Although square “A” appears to be darker than square “B”, they are the same color.

psychedelic eyes

psychedelic clown

The Twinkling Grid or Glowing Grid

This illusion was discovered by the author E. Lingelbach in 1994. In it, if we do not look at a specific point and we dedicate ourselves to looking at the image in general, we perceive black dots and white dots alternating at the intersections.

On the other hand, if we stare at any intersection, we will verify that there is no black point. Again, this is a product of our perception.

How big are the cars?

In the image above it seems that the cars are of different sizes but… Look at the following image:

Jastrow’s Illusion

The discoverer of this illusion was the American psychologist Joseph Jastrow in 1889. In the image above, it appears that figure A is smaller than figure B. It is not, both are equal.

square illusion

The image square appears to be irregular. Instead, it is completely regular. This is because the way the black boxes are arranged makes us see it distorted.

Where is the chair facing?

At the beginning of the GIF it seems that the image is looking to one side, but when the man sits down we realize that he was looking to the other.

Rotating Circles Illusion

In order to perceive this optical illusion, we have to fix our gaze on the center point for a few seconds. Next, we will tilt our heads forwards and backwards. Can you see how the circles move?

How many legs does the elephant have?

How many legs would you say this elephant has? Although it seems that he has more, he only has 4.

Muller-Lyer illusion

Looking at the image, the line in the center of the image on the right appears longer. However, this is due to the placement of the horizontal lines at the ends.

Being in an outward orientation, in the image on the right the line in the center is perceived to be longer. That is, there is an effect of lengthening or shortening the length of the segment.

Center point optical illusion

This illusion is perceived if we keep our eyes on the central point of the image. When we do this, the dark center of the image expands. In reality there is no such expansion. It is a product, once again, of perception.

rubin vase

This is another of the most famous optical illusions, as it has been used in Gestalt psychology.

It was developed by the Danish psychologist Edgar Rubin in 1915 in his work Synsoplevede figurer (in Spanish visual figures). This image represents a double vision, on the one hand that of a vase and on the other that of two faces looking at each other face to face.

Two women or…

double image illusion

In this other image, you can see both a saxophonist and a girl’s face, although one is usually perceived more quickly than the other depending on the person. Can you see both?

Something similar happens with this other illusion; you can see three people in a musical scene or two old people face to face.

white-black circle-Koffka ring

The first semicircle on the left appears to be white, while the semicircle on the right appears to be black… However, they are the same.

You do not believe me? Isolate the semicircles with your hand and you will see.

Blivet 2-3

This is one of the most famous optical illusions. Has 2 tips rectangular at one end that become 3 teeth cylindrical in the other.

Do you see anything else besides the mountain?

A pareidolia is an illusion created by the brain of seeing faces in nature or in other places, such as houses, bags, or any type of object.


Stay looking at the bulb for 25 seconds. Then look at a white sheet or white wall. Do you see? You should see a bright bulb.

squares that appear to move

to hallucinate

Have you ever wondered what it feels like to hallucinate? Well now you can know with this illusion. If you keep looking at the center you will see that you begin to see different movements. Also, every time you blink or look away, the movement will change.

If you stare for 30-60 seconds and then look back at the room you are in, you may still see «hallucinations.»

Man or horse?

boats and bridge

giant seagull

Although it may seem otherwise, the seagull is not giant. It seems so because he is close to the lens of the camera that took the photo, while the man behind is far away.

Mouse or lion?

Whole glass or half glass?

Yes, it is a whole glass, even though it looks like it has an opening inward.

Is it a raven or something else?

The image above looks like a crow that has caught a man or boy. However, if we turn it around you can see the man with a big fish:

long and wide tables

Which of the tables is longer? They are actually the same. Because the one on the left is narrower, it looks like it’s longer.


How many triangles are in the image? There is none, but the brain fills…
