Have you ever wondered how a blind person see? Do they live in a different kind of universe? What do they “actually” see? Well, we have an answer now. It is not an “actual” answer, but it is an explanatory answer which it could explain how a blind person sees. We read two different articles that explain about blind people and the optical illusions of colors. Right down below are the two questions I answered in physics class of my comprehension from the article
- What do blind people actually see?
Blind people actually do see the thing that is indescribable. It is this nothingness that they see. A “normal” human cannot explain this nothingness because nothingness that could be explained is “how it “looks” behind your head.” Nowadays, blind people can live their normal lives like us; it is just that fact that they do not have that one sense of vision. Mr. Wächter is the subject of the experiment of the article. He is a blind man who has put on a belt whose ability can release out the vibration, which it can tell Mr. Wächter any direction. But when the experiment was over, without the belt, Mr. Wächter can still feel some vibration known as, but he was lost. “He was experiencing the same thing you do when you try to look at what’s behind your head.”
- Why colors can trick us?
Colors can trick us when our brain tries to perceive or figure out what is the object’s color. According to Wired’s explanation, when you are concentrating on the figuration of the object’s color, our brain will neglect the background colors and light around it. Colors are also tricky when it comes to your eyes need to subtract the lighting or background colors because it is not happening rapidly. As a well-known example, some people might see the dress in white and gold while others see it as blue and black. For the people who perceive the color in white and gold, you cannot just tell your eyes or brain to neglect the right background colors and lighting. Consequently, all of these theories or ideas have become an inspiration for many artists to create the art of optical illusions. Humans know what is the optical illusion, but it takes to make us realize that it is a trick from colors.
