The Mona Lisa Illusion is an optical illusion that occurs when viewing an image of a person’s face. It is named after the famous painting by Leonardo da Vinci, the Mona Lisa, which is known for its enigmatic smile.
The illusion occurs when a viewer looks directly at the eyes of a person in an image, but perceives the mouth as smiling or frowning. This happens because the viewer’s peripheral vision picks up on the subtle upward or downward turn of the lips, while the eyes remain fixed in the center of the image.
The Mona Lisa illusion is a type of perceptual ambiguity, where the brain has to choose between competing interpretations of the same image. It is a common example of how the brain makes assumptions and fills in missing information based on context and prior knowledge.

How does The Mona Lisa Illusion work?
The Mona Lisa illusion works because the human visual system processes information in different ways, and different parts of the brain are responsible for interpreting different visual features.
When we look at an image, our eyes focus on a small area in the center of the image, which is called the fovea. The fovea has the highest density of photoreceptor cells, which allow us to see fine details and colors.
However, our peripheral vision, which covers the area surrounding the fovea, is less sensitive to details and colors. Instead, it is better at detecting overall shapes, movements, and contrasts.
In the case of the Mona Lisa illusion, the eyes are drawn to the eyes of the subject in the image, which is the most detailed and complex part of the face. The mouth, on the other hand, is less detailed and less well-defined in the painting.
When we look directly at the eyes, our brain processes the visual information from the fovea, which sees the mouth as a blurry and ambiguous shape. However, our peripheral vision picks up on the subtle shadows and contours around the corners of the mouth, which can be interpreted as a smile or a frown.
Since the brain is constantly trying to make sense of the visual information it receives, it makes assumptions based on context and prior knowledge. In the case of the Mona Lisa, the enigmatic expression of the subject, combined with the ambiguity of the mouth, creates a perceptual puzzle that the brain tries to solve. This results in the Mona Lisa illusion, where different viewers may perceive different emotions in the same painting.
Famous Artists who Also Use Anamorphosis in Their Art
Anamorphosis is a form of optical illusion in which an image appears distorted when viewed from a certain perspective and can only be seen in its proper form when viewed from a specific angle or using a mirror or special lens. The word “anamorphosis” comes from the Greek words “ana,” meaning “again,” and “morphe,” meaning “form.”
Anamorphosis was used extensively in the Renaissance and Baroque periods as a way of creating intriguing and often thought-provoking images. Artists would paint anamorphic images on a flat surface and then place a mirror at a specific angle in order to create the illusion of a three-dimensional image. The technique was also used to create hidden images that could only be seen from specific perspectives.
In recent years, anamorphosis has been used in a variety of modern art forms, including street art and advertising. In these contexts, anamorphic images are often used to create eye-catching and attention-grabbing displays that appear to change shape as the viewer moves around them.
Anamorphosis is a fascinating and versatile technique that demonstrates the interplay between art and science, and highlights the importance of perception and the role that context and perspective play in shaping our interpretation of the world.
Anamorphosis has been used by various artists throughout history, including some of the most famous and influential artists of their time. Here are a few notable artists who have used anamorphosis in their work:
Leonardo da Vinci: Da Vinci was one of the earliest artists to experiment with anamorphosis and is widely regarded as one of the pioneers of the technique. He used anamorphosis in his sketches and drawings to represent three-dimensional objects on two-dimensional surfaces.
Hans Holbein the Younger: Holbein was a German artist who lived in the 16th century and was known for his portraits, paintings, and drawings. He used anamorphosis in his portraits to create striking and unusual effects, and many of his anamorphic paintings are still regarded as some of the finest examples of the technique.
René Magritte: Magritte was a Belgian surrealist artist who was known for his paintings, illustrations, and collages. He used anamorphosis in his paintings to create illusions and to challenge the viewer’s perception of reality.
M. C. Escher: Escher was a Dutch graphic artist who is widely regarded as one of the greatest artists of the 20th century. He used anamorphosis in his prints, lithographs, and drawings to create impossible objects and to challenge the viewer’s perception of space and time.
These are just a few of the many artists who have used anamorphosis in their work, and there are many other artists who have also explored this fascinating technique. Overall, anamorphosis is a powerful tool for artists to create striking and unusual effects, to challenge the viewer’s perception, and to demonstrate the interplay between art and science.
Illusions like The Mona Lisa Illusion
The Mona Lisa illusion is a type of visual illusion known as a “perceptual ambiguity” or “ambiguous image” illusion. This means that the image can be interpreted in more than one way, and the brain has to choose between competing interpretations.
In the case of the Mona Lisa, the ambiguity arises because the mouth of the subject is not clearly defined, and the shadows and contours around the corners of the mouth can be interpreted as either a smile or a frown. Different viewers may perceive different emotions in the same painting, depending on their individual interpretation and prior knowledge.
Perceptual ambiguity illusions are fascinating because they demonstrate how the brain makes assumptions and fills in missing information based on context and prior knowledge. They highlight the complex processes that occur in the visual system when we perceive the world around us, and they challenge our assumptions about what is real and what is illusory.
Some similar illusions are as follows:
Trompe-l’œil is a French term that means “trick the eye.”
It refers to a style of art that uses realistic depictions of three-dimensional objects to create the illusion of depth and a life-like appearance.
Trompe-l’œil paintings and murals are often used to create the illusion of an extended space or to make a room appear larger than it actually is.
“The Ambassadors” is a painting by the German Renaissance artist Hans Holbein the Younger, completed in 1533. The painting depicts two ambassadors, Jean de Dinteville and Georges de Selve, who were sent by King Francis I of France to the court of Henry VIII of England.
The painting is known for its complex composition and the many visual elements that are incorporated into the design. The two ambassadors are depicted in a room that is filled with rich details, including a carpet, a table with books and instruments, a lute, and a crucifix. The floor is tiled with a detailed geometric pattern, and the walls are covered with shelves of books and other objects.
One of the most striking aspects of “The Ambassadors” is the distorted skull that is placed in the foreground of the image. This skull, which is painted in a striking trompe l’oeil style, has become one of the most famous elements of the painting and has been interpreted in a variety of ways over the years. Some have interpreted the skull as a symbol of death and the transience of life, while others have seen it as a reference to the memento mori tradition in Renaissance art.
Anamorphosis is a technique in art and optics that involves creating an image that appears distorted or irregular when viewed from one perspective, but appears normal or regular when viewed from another perspective or with the use of a specialized tool, such as a mirror or a cylindrical lens.
The hollow face illusion is a type of optical illusion where a concave mask appears as if it is a convex object.
When a person views a hollow mask from the front, the features on the surface of the mask appear to be bulging out, even though they are actually recessed.
This illusion is created by the brain’s interpretation of the visual information it receives from the eyes. The brain uses previous experiences and knowledge to make assumptions about the shape and position of objects in a scene, and in the case of the hollow face illusion, these assumptions lead to a misinterpretation of the actual shape of the mask.

The Thatcher effect is a visual illusion in which it becomes difficult for the brain to perceive the deformities in an upside-down face. The effect was named after Margaret Thatcher, the former British Prime Minister, who was used as an example in early studies of the phenomenon.
When the face is upright, the brain processes its features holistically, taking into account the spatial relationship between the eyes, nose, mouth, and other facial features. However, when the face is inverted, the brain has to process the features separately, which can make it difficult to detect subtle changes in the features. In other words, the brain has difficulty recognizing that the features are upside down, and as a result, it fails to detect abnormalities.
The Thatcher effect illusion is often used by researchers to study how the brain processes faces and other visual stimuli. It is also used in psychology to study how the brain perceives and interprets visual information, including the processing of emotional expressions.
Artwork by MC Escher. M.C. Escher is widely known for his mathematically inspired and often impossible constructions, and his works are characterized by their playfulness, intricate details, and optical illusions. Some of his most famous works include:
“Relativity” – A lithograph that depicts a world where gravity and direction are relative and interchangeable.
“Waterfall” – A woodcut print that features a seemingly impossible flow of water that cascades upward and through a gear system before falling back down into a pool.
“Sky and Water I” – A woodcut print that features an intricate pattern of birds and fish that seem to transform into each other.
“Day and Night” – A woodcut print that features a world where the boundary between day and night is fluid and interchangeable.
“Metamorphosis III” – A lithograph that features a series of interlocking shapes that seem to change and transform into one another.
“Hands Drawing Hands” – A lithograph that features a series of hands drawing hands, creating a never-ending cycle of creation.
These works, and many others by Escher, continue to captivate and inspire audiences with their intricate details, playful illusions, and mathematical elegance.
Forced perspective is a technique used in photography, architecture, and other visual arts to manipulate the perception of the size and distance of objects.
It creates the illusion of a larger or smaller object, or of one that is closer or farther away, by carefully controlling the angles, proportions, and placement of objects in the scene.
The Ponzo illusion is a type of visual illusion in which a pair of parallel lines, or a horizontal bar, appear to be of different lengths based on the presence of a converging or diverging set of lines, often resembling the converging parallel lines of a road or railway track, placed above and below them.
The Ebbinghaus illusion: This illusion is similar to the Delboeuf illusion but in this case the central circle appears larger when surrounded by smaller circles and smaller when surrounded by larger circles.
The Delboeuf illusion is a perceptual illusion in which the perceived size of a circle is affected by the size of the surrounding circles.
The Occlusion illusion is a visual illusion where an object that is partially obscured by another object appears to be farther away than it actually is. This illusion is caused by the brain’s interpretation of the relative depth of the objects based on their relative size and position. This phenomenon is based on the visual cues that the brain uses to perceive depth, such as relative size, position, and overlap.
The Müller-Lyer illusion is a classic example of size-contrast illusion, in which two lines of equal length appear to be different due to the presence of arrowheads or fins at the end of the lines.
The moon illusions involves the perception of the Moon appearing larger when it is near the horizon compared to when it is high in the sky.
The Kanizsa triangle is a visual illusion that was first described by the Italian psychologist Gaetano Kanizsa in 1955. The illusion consists of a white equilateral triangle that appears to be surrounded by three Pac-Man-like shapes, which are black and have white crescents facing inwards.
Creation of The Mona Lisa Illusion
The Mona Lisa is a portrait painting by the Italian Renaissance artist Leonardo da Vinci. It is also known as La Gioconda or La Joconde in French. The painting is widely considered one of the most famous and enigmatic works of art in the world.
The painting depicts a woman, believed to be Lisa Gherardini, the wife of a Florentine merchant, sitting in front of a rocky landscape with a winding road and a bridge over a river in the background. She is shown with her hands folded in her lap and looking directly out at the viewer with a faint smile on her lips. Her gaze is intense and enigmatic, and the painting has been the subject of much speculation and interpretation over the centuries.
Leonardo da Vinci began painting the Mona Lisa in 1503, and it is believed to have taken him several years to complete. The painting is an oil on poplar wood panel and measures 77 x 53 cm (30 x 21 inches).
Leonardo was known for his meticulous attention to detail and his use of sfumato, a technique of blending colors and tones to create soft, hazy edges and a sense of depth and atmosphere. He also used a technique called chiaroscuro, which uses contrasts of light and dark to create a three-dimensional effect.
The Mona Lisa was not widely known or appreciated during Leonardo’s lifetime, but it gained popularity in the 19th century and has since become one of the most famous and iconic paintings in the world. It is now housed in the Louvre Museum in Paris, France, where it is viewed by millions of visitors each year.
Leonardo da Vinci was an Italian artist, scientist, inventor, and polymath who lived during the Renaissance period. He was born on April 15, 1452, in the town of Vinci, near Florence, Italy, and died on May 2, 1519, in Amboise, France.
Leonardo is widely considered one of the most important and influential figures in the history of art and science. He was a master of many different disciplines, including painting, sculpture, architecture, engineering, anatomy, mathematics, and astronomy.
As an artist, Leonardo is known for his meticulous attention to detail, his use of light and shadow, and his ability to capture the complexity and subtlety of human emotions. His most famous works include the Mona Lisa and The Last Supper, both of which are considered masterpieces of Renaissance art.
In addition to his artistic achievements, Leonardo also made important contributions to science and technology. He conducted pioneering studies of human anatomy, designed flying machines and submarines, and made advances in the fields of optics, mechanics, and hydrodynamics.
Leonardo’s work continues to inspire and influence artists and scientists to this day, and he remains one of the most celebrated and revered figures in human history.
