Watch the video: Fascinating illusion – these flashing circles deceive your senses.
This is proof you can’t believe your eyes…
These two circles appear to flash in exactly opposite directions.
But is that really true?
This is an optical illusion.
If we hide the black and light gray background, it becomes clear that the two circles are actually flashing exactly synchronously.
The reason:
The perceived brightness of a surface is always influenced by the surroundings.
Depending on whether the circles are black or light gray, they alternately stand out from the background.
Once again impressive proof of how our perception can deceive us.
