Some optical illusions that made you crazy!

+7

Hello again! Now, I'm going to show some optical illusions that made you crazy!

Sources: Wikipedia and Segredos do Mundo

First, we are going to see what is an optical illusion.

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions.

OK, so, an optical illusion it’s an illusion that happens when our brain doesn’t process information well, and ends up generating another one, which when we see it, something very different.

Now, let's have fun, and see these optical illusions!

1. Rotating rings

If you fix your eyes on the point in the center and move the head away from the screen, the rings will begin to rotate. Now gradually get closer again...

2. Hermann's grid

Hermann's grid was named Ludimar Hermann, who discovered it in 1870. Everywhere the white lines cross, our eyes see gray dots. If you look directly at one of the intersections, the point disappears.

3. The image that disappears

Stare at the image for about half a minute without moving your eyes and watch it gradually disappear...

4. Kanizsa Triangle

Kanizsa's triangle was named after the psychologist Gaetano Kanizsa, who described its effect. When you look at the image, your brain creates outlines of a triangle, although it does not exist.

5. Blivet

This is one of the most famous impossible objects. It has two rectangular teeth at one end that turn into three cylindrical teeth at the other.

6. Monsters of the same size

Found in virtually every psychology book in the world, the two monsters of this illusion are, in fact, the same size. Your brain automatically adjusts images that seem distant to compensate for being the same size.

7. Jastrow

Named by Robert Jastrow in 1889, figure "B" appears to be larger, although they are the same size. This is because the shortest edge of "A" is directly adjacent to the longest edge of "B".

8. Fraser's Aspiral

Described by British psychologist James Fraser in 1908, this aspiral is known as the "false spiral". Although it appears that the overlapping arcs are spiraling at infinity, they are in fact just a series of circles.

9. Sparkling grid

This is a variation of the Hermann Grid, where black dots appear and disappear at the intersections of the white lines. Interestingly, if you twist your head at a 45 degree angle, the effect is reduced (but not eliminated).

10. Blue vs Green

There are many variations of this effect, but they all have the same principle. The "blue" and "green" backgrounds are in fact the same color.

11. Endless staircase

This is a variation of the infinite ladder. Like the blivet, this is also an impossible object and is sometimes called a “Penrose triangle”.

12. Black on white

Look at the center of the image for about 30 seconds and then look away at a preferably white surface (sometimes the ceiling works). What do you see?

13. Zöllner

This effect was named by Johann Karl Friedrich Zöllner and consists of parallel lines that appear to be diagonal. You may need a ruler to check.

14. Hering illusion

Although the two red lines appear curved outward, they are perfectly straight and parallel. This effect was discovered by Ewald Hering.

15. Titchener circles

Also known as the Ebbinghaus Illusion, there is still debate in psychological circles as to the exact mechanism and implication of this effect. Essentially, the orange circle on the left appears to be smaller than the one on the right, although in reality they are the same size.

16. Leaning tower

Yes, the Tower of Pisa is actually tilted, but the two images above are identical, and neither is tilted. Although the image on the right appears to be moving away from the left, it happens only in your head.

17. Wonder block

Once again, we have an example of an impossible object. Are the blocks side by side or on top of each other? Perhaps that is why they call them indecipherable figures.

18. Floating stairs

For centuries, artists have explored the limits of perception and, if you are lucky, and at the right angle, you can see the effect.

19. The turning of the silhouette

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

20. Up and down

While it is obvious that the cylinders of this illusion remain in the same horizontal position, our brain is convinced that they are moving to the right.

21. Moving squares

At first, this effect can be difficult to see, but if you start moving your eyes from side to side, you will notice that the squares start to rotate. As soon as your eyes stop moving, the rotation will stop.

22. Static movement

The image is really static. Note that when you look at any individual point, it will stop moving. This powerful optical illusion is derived from interactive color contrasts.

23. Lilac Chaser

Also known as the pac-man effect, if you look at the center of the cross for a few seconds, you will start to notice that the lilac circles will start to change color, going to green. After a few more seconds, all the lilac circles will gradually disappear until all you see is a green disc in a circle around the cross.

24. Coffee wall

Another famous optical effect. This was recently rediscovered on a wall in a cafeteria. Although the lines appear to diverge from each other, they are in fact quite parallel.

25. Shadow Effect

Probably one of the most unbelievable illusions, this was the first optical effect published by MIT professor Edward Adelson. Although the “A” square appears to be darker than the “B” square, they are exactly the same color. If you don't believe it, use any image editing program to check it out.

Liked? So stay open to the news here on my blog! Thank you very much for that minute of attention, and until the next post!

Netinho, acho que precisa piscar os olhos mesmo. Uma vez passei por isso na luz que tinha na igreja que eu congrego. E aquela luz era muito forte. Fiquei fixado nela e comecei a piscar. Quando isso acontecia, aparecia a luz.
