7 Cool Optical Illusions and How Each of Them Work

Optical illusions, often known as optical illusions, involve deception of the eyes. A wide range of misleading visual illusions can be perceived due to the arrangement of images, the effect of colours, the impact of the light source, or other circumstances.
You may have realised that not everyone experiences visual illusions in the same way if you've ever struggled to see the hidden image in a single-image stereogram. Some people are unable to see the effect of certain illusions.

Another amusing example of negative afterimages with an unexpected consequence. The negative photo illusion involves your brain and visual system converting a negative image into a full-color one.
