Why is this optical illusion so difficult?

In this viral illusion, only ’16’ appears everywhere. All the numbers are written in the same font style and pattern, making it almost impossible to spot 19. The viewer’s mind repeats the same number over and over again, which is why 19 is not visible.

This is the speciality of optical illusions: what is in front is not visible, and what is hidden is what takes the most time to find.

Why are optical illusions solved?

Optical illusions are not just entertainment, but also mental exercises. They strengthen the coordination between the mind and the eyes and enhance our cognitive skills in many ways.

  •  Improves Observation Skills – The ability to perceive details in images is sharpened. This also proves helpful in everyday life.
  • The mind gets a new perspective – When the eye sees something that the mind cannot understand, the mind learns to think differently. This improves critical thinking.
  •  Refreshes the mind – In the midst of stress, such fun challenges refresh the mind and relieve mental fatigue for a while.
  •  Impact on Creativity – Artists, designers, and architects often draw inspiration from optical illusions because they enhance visual perception.
