Optical illusions will make you see things that are not real, such as static images that move or the same colors that look different. This happens because your eyes and brain speak a “simple tongue”.
When your brain is trying to quickly fill in the missing information, sometimes it guesses it wrong. For example, in the illusion of Hermann Grid, the illusion of dark spots flashs at the transitions of the white line, although no one exists.
Scientists argue that this mix occurs because your brain has evolved to quickly detect danger, such as predators in shrubs, which helps survival but creates visual errors.
- Physical: caused by light tricks (such as bending pencil in water)
- Physiological: Results of excessive eye/brain stimulation (concept of bright lights)
- Cognitive: Brain assumptions are wild (faces/vases switching in Rubin’s illusion)
The famous illusion of Müller-lyer shows two same lines that appear different lengths due to arrows similar to the tail. This “distortion of illusion” proves that your brain judges based on the surroundings. Similarly, photographs of “dress” were viral because some brains assumed blue/black (artificial light), while others saw white/gold (natural light).
Viral puzzles train your focus
Online illusion such as observation skills hidden cats. In one, the cat perfectly masks in the bushes, only 5% place it within 7 seconds. Such puzzles focus attention to details and are transferred to improving real -life focus.
Other popular tests include:
- Finding an owl in the woods
- Counting hidden animals
- Observing differences in Twin pictures
These games reveal how evolutionary vision: Early people needed skills in masking detection for hunting and survival.
Optical illusions are not just fun, help doctors to monitor the pain of schizophrenia and phantom limbs by revealing how brains process sensory conflicts.
Artists as MC Escher used the techniques of illusion (paradoxical illusions) to create staircases for the bending of the mind. For all others, practicing with illusions increases patterns recognition, useful for reading X -rays, notification of road risks or even finding lost keys.
