The Most Well-Known Optical Trick
When we look at these images, what we see is sent to our brains, and a false perception is created, because the image our brain processes is not actually what is in front of us. Different people often see these illusions differently, which is normal because everyone's mind works in different ways, and there are many different types of optical illusions.
Trick on the Cafe Wall
Although it appears that these lines are sloping up or down, the horizontal lines are all parallel. Use a sheet of paper to cover the top and bottom of one line of squares. The lines will run parallel to each other.
The Lyre of Muller
Which horizontal line, the top or the bottom, is the shortest? Even though your brain knows the line with the outside wings is longer, they are the same length.
The ruse of Zollner
When you cover the rest of the lines and focus on only two lines, the diagonal lines appear non-parallel, but they are actually parallel.
Trick with the Shimmering Grid
Your brain believes there is a black dot inside each white circle, therefore you won't notice there were no black dots until you focus just on each white circle.
One of these yellow lines appears to be longer than the other, but closer inspection reveals that they are exactly the same length, as the line appears larger as you move closer to it and smaller as you get further away.
Trick with elephant legs
What is the number of legs on an elephant? The answer may appear obvious at first view, but if you look closely, you will notice that the elephant's legs overlap, making it impossible to calculate the right number of legs.
optical illusions that are animated
One of the most well-known optical illusions is the one in which you see a fixed image moving, and the following are some of the more notable examples:
Despite the fact that all of the seeds in the image are immobile, they will rotate.
circles that rotate
When you concentrate on one circle, the circles surrounding it appear to spin, but they are absolutely still.
ball of hypnosis
The background appears to be a circle, although both are completely still.
polka dot ball
The ball will appear to be rolling on the polka dot's surface, and the background beneath the ball will appear to be moving down, although this image is absolutely static.
a trick using waves
Although these circles appear to be moving in a wave, they are actually immobile and do not move.
Color spinning trick
Even though it is a static image, the colours appear to rotate around each other.
optical illusions in black and white
One of the most well-known optical illusions is the black-and-white illusion, most notably:
a secret message
If you look at the photo long enough, you'll see a secret message concealed in the black dots, and you'll be able to close your eyes in half.
Tricks on the inside and outside
Is the layout's smallest point pointing inward or protruding outward? Because of the random streaks, it's impossible to determine.
The trick is to figure out which window is larger.
Trick with Big and Small Dots
Which blue dot, the one on the left or the one on the right, is the larger? You may think the one on the left encircling the larger circles is smaller than the one on the right, but they are the same size.
The trick with the square area
Trick with Connecting Lines
trick with red squares
The red squares on the left appear crooked, whilst the red squares on the right appear straight.
trick with zigzag squares
These squares' lines are exactly straight up to the ones in the centre, but arranging the smaller squares inside the larger squares makes the entire shape stand out.
lines should be bent
Although the red lines appear to be curving outward, they are absolutely straight.
The ruse of Edwin Boring
You can see a young woman looking away or a profile photo of an elderly woman in this image, and you can see both, but our minds can only focus on one at a time.
Trick with the vase by Robin
Do you notice a bowl shape or the profile of two people looking at each other at first glance? It all depends on which hue you choose to concentrate on.
Trick a pair of pears
Which of these pears is lighter, the one on the left or the one on the right? These two pears are exactly the same color, but you will see the different tones due to the black lines.
monster length trick
Which monster is taller and closer to you? These two monsters are not the same size in terms of length and distance, but they are the same size in terms of length.
