Optical illusions blur the vision and blur the imaginary and real border.
Iltalehti collected several optical illusions under the same story. See if the images move or are they still?
Curved line
Reddit in the publication you can see black and white patterned tiles with green lines in between. Can you spot a curved line in the crowd?
Answer: There is not a single curved line in the picture. All tiles are bordered by straight green lines that run vertically and horizontally.
The coloring of the picture is said to cause the optical illusion that the lines would curve at different points when looking at the picture.
Green pattern
Does the background of the picture move in waves or does it stay still? You can take a closer look by moving the image even back by scrolling up and down with the mouse.
In reality, the background is in place, but the eyes create an effect that makes the image ripple when you look at it.
Black hole
Look directly at the black spot. It appears to be expanding even though it is not actually moving. Reddit publication according to some do not see the black spot moving at all? Do you see an optical illusion in the picture?
