How Do Optical Illusions Work?

Jun 26,  · Optical Illusions An optical illusion is something that plays tricks on your vision. Optical illusions teach us how our eyes and brain work together to see. You live in a three-dimensional world, so your brain gets clues about depth, shading, lighting, and position to help you interpret what you see. Optical illusions, more appropriately known as visual illusions, involves visual deception. Due to the arrangement of images, the effect of colors, the impact of light source or other variables, a wide range of misleading visual effects can be seen.

Optical illusions are presentations of illusiohs as well as situations in such a way, that it confuses your vision, and projects double meaning of the same image to you simultaneously. Optical illusions ilusions really fun to see, illuusions they confuse us about what the picture really is, and play with our minds. So, for you to enjoy seeing some optical illusions and have your mind really confused, here is a list of some superb and mind-blowing optical illusions that will surely leave you confused and wondering, figuring out the real situation in the images.

Optical Illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image. Perception refers to the interpretation of what we take in through our eyes.

Due to the arrangement of images, the effect of colors, the impact of light source or other variables, a wide range of misleading visual effects can be seen.

If you've ever struggled to see the hidden image in a single-image stereogram, you may have discovered that not everyone experiences visual illusions in the same way. For some illusions, some people simply are not able to see the effect. While optical illusions can be fun and interesting, they also reveal a great deal about the working of the brain. Learn more about some of the most famous optical illusions and discover exactly how and why these visual illusions occur.

In the Hermann Grid Illusion, the white dots at the center of each square seem to shift from white to gray. The Hermann grid was first discovered by a physiologist named Ludimar Hermann in When the viewer looks at the grid, the white dots and the center of each 'corridor' seem to shift between white and gray.

When the viewer focused his or her attention on a specific dot, it is obvious that it is white. But as soon as attention is shifted away, the dot shifts to a gray color. So why do people see gray where there should be white? Why do we see something so different from reality? Researchers have traditionally used what is known as lateral inhibition to explain why people see these gray areas. Our perceptions depend upon how our visual system responds to environmental stimuli and how our brain then interprets this information.

However, there is evidence suggesting that this explanation is likely inaccurate. The fact that the illusion is not dependent upon size, can be seen with contrast reversal and can be negated by slightly distorting the lines have been cited as reasons why the classic theory is wrong.

One possible explanation that has been proposed is known as the S1 simple-cell theory. The spinning dancer illusion shows an ambiguous silhouette that appears to abruptly change direction.

Learn more about how this illusion works. In this image, you see the silhouette of a woman spinning. Which direction is she turning? You may be surprised to learn that it is possible to see her spinning both clockwise and counterclockwise. While it may be very difficult, you can probably get her to switch directions spontaneously.

Try looking at the figure and then blink; she may appear to change directions immediately after you blink. Another strategy is to focus on a specific part of the figure. In reality, the spinning dancer illusion is related to a bistable perception in which an ambiguous 2-dimensional figure can be seen from two different perspectives.

Because there is no third dimension, our brains try to construct space around the figure. People typically see the clockwise variation, which research suggests can be attributed to a tendency to assume a viewpoint from above the figure as well as a tendency to perceive movements of the right as opposed to the left foot.

The oblique lines look as if they are crooked and will diverge. In reality, all of the oblique lines are parallel. Much like the Muller-Lyer and Herring illusions, this optical illusion demonstrates how the background of an image can distort the appearance of straight lines.

First, the angle of the short lines compared to the longer lines creates an impression of depth. One of the lines appears to be nearer to us; the other farther away. Another possible explanation is that the brain attempts to increase the angles between the long and short lines. This results in distortion as the brain tries to bend the lines away and towards each other. Interestingly, if the color of the lines is switched to green and the background to red, the effect completely disappears as long as the two colors are of equal brightness.

In the Ames room illusion, two people standing in a room appear to be of dramatically different sizes, even though they are the same size.

The image above was captured by a visitor to the "Ames room" in the Villette science museum in Paris, France and uploaded to Flickr, a photo-sharing website. In the room, the individual on the left appears to be very tall, while the person on the right looks very small.

In reality, both people are of approximately the same height and size. The effect works by utilizing a distorted room to create the illusion of a dramatic disparity in size. While the room appears square-shaped from the viewer's perspective, it is actually has a trapezoidal shape. The woman on the right hand side of the image above is actually standing in a corner that is much further away than the woman on the left.

The illusion leads the viewer to believe that the two individuals are standing in the same depth of field when in reality the subject is standing much closer. The effect can be observed in a number of films, including The Lord of the Rings trilogy.

Note the early scenes in The Fellowship of the Ring where the effect is prominently used to make Gandalf appear larger than the hobbits. You can see more examples of Ames rooms in these YouTube videos. In the Ponzo illusion, two identically-sized lines appear to be different sizes when placed over parallel lines that seem to converge as they recede into the distance. In the image above illustrating the Ponzo illusion, the two yellow lines are the exact same size. Because they are placed over parallel lines that seem to converge in the distance, the top yellow line actually appears to be longer than the bottom one.

The Ponzo illusion was first demonstrated in by an Italian psychologist named Mario Ponzo. The reason the top horizontal line looks longer is that we interpret the scene using a linear perspective.

Since the vertical parallel lines seem to grow closer as they move further away, we interpret the top line as being further off in the distance. An object in the distance would need to be longer in order for it to appear the same size as a near object, so the top "far" line is seen as being longer than the bottom "near" line, even though they are the same size.

The Kanizsa Triangle is an optical illusion in which a triangle is perceived even though it is not actually there. The Kanizsa Triangle illusion was first described in by an Italian psychologist named Gaetano Kanizsa. In the illusion, a white equilateral triangle can be seen in the image even though there is not actually a triangle there. The effect is caused by illusory or subject contours. Gestalt psychologists use this illusion to describe the law of closure , one of the gestalt laws of perceptual organization.

According to this principle, objects that are grouped together tend to be seen as being part of a whole. We tend to ignore gaps and perceive the contour lines in order to make the image appear as a cohesive whole. Ever wonder what your personality type means?
