Visual phenomena, commonly known as 'Optical Illusion,' introduces us to the realm of visual deception. Within our daily lives, a myriad of optical illusions occurs, from witnessing a rainbow after a rainy day to gazing at clouds. In this fascinating phenomenon, the human brain weaves diverse images to interpret the shape, curve, and size of the clouds.
Optical illusions are instances of judgment errors; they do not physically manifest. Our eyes capture light emitted or reflected by an object, focusing the images onto the retina, where messages are transmitted to the brain.
Located at the back of the eye, the retina contains cells responsive to light. When hit by light, the retina triggers nerve impulses sent to the brain, which interprets the incoming data as light and shadow, form, and color (Bruno, 2011). The eyes serve as a crucial link between reality and the illusion itself.
Three primary types of optical illusion exist: literal illusions, physiological illusions, and cognitive illusions. Psychologists discovered most illusions, and subsequently, these effects found application in creating new illusions for entertainment and amusement, notably by magicians and illusionists.
Literal illusions craft images distinct from the objects that give rise to them.

Physical or literal optical illusions occur before light enters the eye. An example is the Rainbow, where sunlight reflects through airborne water droplets, forming a vibrant arch across the sky (Richards, 2002).
Physiological illusions impact the eyes and brain due to excessive stimulation of specific types, such as brightness, tilt, color, or movement. Afterimages following bright lights or the perception of movement in a still image after prolonged staring are well-known effects (Anastasia, 2009).
Cognitive illusions arise from the eyes and brain's interpretations and perceptions.
Observing two distinct objects within the same picture exemplifies cognitive illusion. This category further divides into four types. Ambiguous illusions depict pictures or objects undergoing shifts or changes. Distorting illusions involve size, length, or curve distortions, while paradox illusions result from paradoxical or impossible objects. Fiction illusions, or hallucinations, entail viewing objects generally nonexistent to all but a single observer (Anastasia, 2009).
The interplay between the human mind and the eyes yields captivating, humorous, and entertaining visual images that lack tangible existence. These optical illusions constitute normal facets of the human experience.
In conclusion, the world of visual deception, encapsulated in the term 'Visual Deception,' unfolds a fascinating panorama of human perception and interpretation. From literal illusions distorting reality to physiological illusions playing tricks on our senses, and cognitive illusions challenging our understanding, optical illusions are woven into the fabric of our daily experiences. As we navigate this captivating landscape, it becomes evident that our eyes and minds collaborate to create a tapestry of visual wonders, reminding us that sometimes, what we see is not always what truly exists.
