Benefits of optical illusion

RESEARCHERS have developed many tests that show how different brain regions respond to optical illusions.

Not only are they entertaining, but they also shed light on how our brains interpret visual data.

By regularly exercising your brain a little, you increase your ability to focus and observe details.

Studies have shown that people who regularly challenge themselves with optical illusions and puzzles see great improvements in their problem-solving skills, concentration and attention.

Improved concentration and attention span can, in turn, help prevent cognitive decline in old age.

Psychologists from the University of Glasgow discovered that staring at an optical illusion can improve vision by allowing you to see small print.
