Optical illusions, which test our capacity to see beyond what is immediately evident, have long fascinated and perplexed people. These mind-bending visuals challenge our view of reality and highlight the brain's tendency to fill in gaps and create assumptions based on incomplete information. Optical illusions remain a prominent topic of research in psychology and art, providing insights into how the human mind interprets visual information. 

Artists and psychologists alike use optical illusions to investigate the complexity of human vision and how easily our brains may be misled. These illusions, which manipulate colours, forms, and patterns, highlight the amazing interaction between our eyes and minds.
