What are Optical Illusions?

1096 Words3 Pages

One wonders what an optical illusion is, “an optical illusion is a visually perceived image that differs from reality.” (Eifrig, 2014, n.p.). There are so many different types of optical illusions in which play with the brains of people. Optical illusions are normal because the majority of humans experience them. Humans’ vision tries its best to figure out what is happening to the picture, which then creates an image contradicting reality. Sometimes illusions can be entertaining because it fools the brain and one tries to figure out the image shown. Illusions cannot only be in a form of art but sometimes it happens whenever reading something without putting much effort.
Optical illusions are images that contradict real life. Meaning that the image created is not really the way it might appear. “Optical illusion can use color, light and patterns to create images that can be deceptive or misleading to our brains” (1) (“Optical illusions”, n.d., n.p). Although the brain is, quite an important part, images can still fool it. Some people might think that it is incorrect to experience illusions but it is normal for optical illusions to occur. A person may think that is it only one that senses illusions but in fact everyone experiences optical illusions.
In order for an illusion to occur, it first gathers information through the eye, and then the brain processes it, which then creates an image. The image that the brain comes up with is on two different perceptions of the image and then ends up creating an image opposing reality and does not match actuality. This is all based on two different perceptions that are made by our eyes and brain. Perception is the analysis taken by the sense of a person. “Optical illusions occur because our ...

    In "On Entering a New Place", Barry Lopez discusses how perception can be deceiving when trying something new that you don't completely understand. Typically, a person would be uncomfortable about the unknown so in their minds they theorize what could be. To continue getting rid of their nerves, they run their ideas through their heads multiple times until they believe that is how it's supposed to be.

    The late author and philosopher Dame Iris Murdoch once said “We live in a fantasy world, a world of illusion. The great task in life is to find reality.” The general argument made by Tim O’Brien in his short story “On the Rainy River” is that an individual’s self-perception may skew the line between illusion and reality. More specifically O’Brien argues that the line may be discovered if an individual is able to come to terms with their perception. Illusion and reality are found to be confused throughout the novella “On the Rainy River” as a journey through one’s own mind is taken in order to reach a life-altering decision.

  • Keith Wilson's Perception And Reality By Keith Wilson

    What is sense perception? Everything we perceive in our senses can be misleading and an illusion. In the article “Perception and Reality” by Keith Wilson (see Article 1), the author goes over some of the aspects of how our perception deceives us to believe in things that aren’t there to begin with. For example are colors real? Well that is relevantly dependent on what is considered real, because real again is a perception of a single individual collecting information and making “sense” out of it. A color being real or not is dependent on how we see it through our eyes, we can 't say that my blue is the same as your blue. We can 't know for sure if what we are seeing for ourselves, is the same as what the person that views that same thing sees

Both authors used the of illusion constituent on in ways resplendent and helped the reader gain a perspicacity into the lives of these characters.

  • Ames Room: A Study of Optical Illusions

    The illusion is so convincing that the person that is admiring the room would think that the figures or persons are different sizes and might be twins, but in reality it is all about how they are collocated ( one is closer than the other one ) and the way the shape of the walls are and how they’re connected. Although theres other studies that show that theres no need for the room to have a ceiling or walls. This happens because the same room can have a horizontal division but in reality is not horizontal against an appropriate background and the eye relies on the apparent relative height of an object above that horizon. However, this effect can be seen in many movies nowadays.

  • Plato's Allegory Of The Cave: The Theories Of Reality

    523 Words  | 2 Pages

    Appearance is what we perceive around us; it is sometimes known as the empirical, which means known through the senses. Reality is most commonly defined as all that exists regardless of whether it is perceived or not; in other words, it exists independently of anyone’s perception.The metaphysical problem of reality and appearance can be described as the difficulty of telling the objective from the subjective. One of the proboems of reality and appearance has already been illustrated by Plato, which is that reality is genuine as opposed to deceptive. He suggests a rationalist approach to answering this question relying on reasons that focused on our senses. Our sensory knowlege and experiences are our only perceptions of reality, but that can still mean that its not really there. All that us humans have are our own paradigms of what reality “really is” which is based upon a series of assumptions and beleifes that in turn, determines their views of reality.

  • Exploring Views on Human Nature: From Hobbes to Rousseau

    1493 Words  | 3 Pages

    Since most people get their truth through the senses, human nature is uncertain because the senses sometimes are unreliable. The senses are deceptive especially when our experiences are just dreams, not sense perceptions. The “dream argument” by Descartes is a perfect example. What happened in the “Dream argument” is that the Mediator dreamed of clothing in dress gown, but the reality is that he was actually undressed in bed. The only way of knowing the truth is by waking up because it is very difficult to differentiate a dream moment from a waking moment when asleep. The idea of experiencing real things in our dreams, while we actually aren’t is the reason why our senses deceive. Watching the sunrise and sunset is another good example of sense deception. When we see sunrise and sunset, it seems like the sun is moving. I assume that the sun moves because I can see it

  • Illusion vs. Reality in Macbeth

    1741 Words  | 4 Pages

    Reality is the state of being real or actual, whereas an illusion is a mental misinterpretation of what is believed to be true. Illusions often prevent people from perceiving reality and objective truths, which consequently results in delusions, and in some cases, tragedies. In Macbeth, a play written by William Shakespeare, the theme of illusion versus reality is overtly evident in the main character, Macbeth. Macbeth frequently misinterprets illusions as the actual reality due to possessing such an untamed ambition, which ultimately ends up resulting in a series of tragic and horrific events, for Macbeth and his victims. Macbeth’s ambition first leads him into believing that he is destined to become King of Scotland, which results in Duncan’s death. Macbeth’s ambition then affects his mental health, which causes him to mistake his hallucinations for reality, eventually resulting in further detrimental acts. Finally, Macbeth’s ambition blinds him into living a life of delusion, which causes him to reach his peak of arrogance and optimism, resulting in even further detriment and ultimately his very fall. Just as ambitions are incredibly illusive and detrimental in Macbeth, they can also be incredibly illusive and detrimental in our actual, modern day society.

  • My Philosophy of Mathematics Teaching and Learning

    1307 Words  | 3 Pages

    As a secondary subject, society often views mathematics a critical subject for students to learn in order to be successful. Often times, mathematics serves as a gatekeeper for higher learning and certain specific careers. Since the times of Plato, “mathematics was virtually the first thing everyone has to learn…common to all arts, science, and forms of thought” (Stinson, 2004). Plato argued that all students should learn arithmetic; the advanced mathematics was reserved for those that would serve as the “philosopher guardians” of the city (Stinson, 2004). By the 1900s in the United States, mathematics found itself as a cornerstone of curriculum for students. National reports throughout the 20th Century solidified the importance of mathematics in the success of our nation and its students (Stinson, 2004). As a mathematics teacher, my role to educate all students in mathematics is an important one. My personal philosophy of mathematics education – including the optimal learning environment and best practices teaching strategies – motivates my teaching strategies in my personal classroom.
