Blue eyes

iris pigmentation? Only 10,000 years ago, someone who lived near the Black sea developed a mutation, which resulted in blue iris pigmentation (Eiberg, 2008). The iris consists of small connective tissue surrounded by muscular structure with a central opening known as the pupil (Sturm, 2008). This pupil allows the eye to control the amount of light, which enters to allow they eye to focus the lens to the retina. This sequence allows for a sense of vision (Sturm, 2008). The pupil contracts as…

mind. While the cognitive theory emphasizes mental processes involved in numerous actions, such as remembering, solving problems, and thinking. In short, the eye takes in light rays and converts them into electrical and chemical signals that are interpreted by the brain to form physical images. This process requires communication between the eye, a sensory organ, and brain, the core of the central nervous system. Electromagnetic rays, in the form of light, must pass through the cornea, which…

American Jazz sensation, Miles Dewey Davis III was born in Alton, Illinois, on May 26th 1926. The nine time Grammy winner is considered to be one of the top musicians of his era. He forever changed the style of jazz and history of music. Throughout his years in music, he has proven to be a universal musical genius that was able to stretch his style of sound for miles. Davis grew up in a middle class home with his parents, Miles Davis Jr. and Cleota Henry. His father was a successful oral…

art. Even though the first look makes Jackson Pollock's Blue Poles painting seem like child's play, a closer evaluation of the contrast, time involved, and interest reveals an effective piece of art. Contrast between light and dark is one of the most important parts of an effective piece; a criteria Blue Poles has effectively used. Without light and dark, there will be no shape and the image will be very flat. For Blue Poles, the dark blue is the darkest shade there is; to counter the darkness,…

Colors have different meanings to different people. Some colors remind people of events that have happened, while others remind people of different seasons or places that they have been. In F. Scott Fitzgerald’s novel, The Great Gatsby, the author uses color symbolism in a creative and juxtaposed way that allows him to emphasize different themes. The main character, Jay Gatsby, wants to marry his long lost love, Daisy; however, she has married another man named Tom, who comes from “old money”.…

December 17, 2009, one cold, chilly morning. The sky seemed covered with a layer of gray yarn; the snowflakes like the thousand butterflies flies toward the windows, some naughty hitted the one side of window glass, and some danced to the other side. I stepped into a brown building and straight to the main office. After I registered, a lady with an amiable smile, who I know laterly as Mrs. White, greeted me with a zealous voice “ Welcome to Hillside Middle School, Yiwen.” My first school day…

Ocular Dominance Affect the Way We See Things? Eyes are what allow our brains to process information, whether it’s to see color or to give the ability to read. They are organs that even allow us to evaluate our health, and can be used to express emotion. Everyone has them and each one is different, but they share a common purpose, and it’s important to know how they work. Light passes through the cornea of the eye, which has the job of protecting the eye and refracting the light so some of it…

organ (the eye) and the core organ (the brain) to understand external stimuli. The eye is extremely complex and requires various components for it to complete its function. The eye has 3 main layers the sclera, which maintains and supports the shape of the eye; the choroid, which provides oxygen and nourishment to the eye and includes the pupil, iris, lens; and the retina, which allows us to piece images together and includes two types of photoreceptors, cones and rods which helps the human eye…

recognizing and interpreting sensory stimuli, from our sense organs: eyes, ears, skin, nose, and tongue. Our vision comes from our sense organ, our eyes and travels to the part of the brain that processes vision, the occipital lobe. From there what we see is a perception of what we are getting from our sense organ. Our perception of color in particular is shaped by the culture that we live in and biologically through the rods and cones in our eyes (How vision works, 2015). The way that the…

Are dogs colorblind? the answer yes/ no, they see in color, just not the way humans do due to the lack of certain cones in their eyes. Moreover, how does color blindness work in humans? To see how color works we first have to analyze how we perceive color. The way we see “Color” is determined by the wavelength of a stream of light. This means that each color of light has its own wavelength. The combination of all lightwaves (primary colors) produces white. The absence of lightwaves makes an…
