Optical illusions benefits
RESEARCHERS have developed many tests that show how various brain regions react to optical illusions.
They are not only entertaining, but they also shed light on how our brains interpret visual data.
By giving your brain a little workout on a regular basis, you enhance your ability to focus and observe details.
Studies have shown, people who regularly challenge themselves with optical illusions and puzzles see big improvements in their problem-solving skills, concentration and attention.
Improved concentration and attention span, in turn, can help prevent cognitive decline in older age.
Psychologists at The University of Glasgow found that staring at an optical illusion can improve eyesight by allowing you to see small print.
This brainteaser has been made particularly tricky through the varying shades of vibrant colours in the background.
The artistic detailing that has gone into the image - with the children running frantically, bright headbands, shoes and clothing items - has offered the perfect camouflage for the teddy bear.
The busy nature of the image has made it extremely hard for our eyes find it hard to focus on any one object.
