Color Blindness and its Effects On Humans
Many People have 20-20 vision (“normal" vision is 20/20. This means that the test subject sees the same line of letters at 20 feet that person with normal vision sees at 20 feet). Lots of people wear glasses, however did you know that 8% of males and 0.5% of females can’t fully see colors. This disease or illness is called Daltonism, after the scientist Dalton but it’s most commonly referred to as color blindness. Color blindness happens because of cones in the eyes, there are different types of it and it is inherited but can also happen by diseases and drugs.
According to Britannica (2015), color blindness is caused because of the cones in the eyes. It happens when one or more cones are either weak, damaged or non-existent. In the retina of the eye (the light-sensitive layer of tissue that lines the back and sides of the eyeball), humans have three types of cones (the visual cells that function in the perception of color), the red, green and blue cone. A damaged or weak cone means that the person can’t see the color on different shades of light or when it’s blended with other colors, a non-existing cone means that he/she can’t see that particular color. In conclusion, Britannica says that colorblindness are mostly about the cones that are in the eye. …show more content…
There are actually labeled by the cone’s weakness or the cone’s existence. Protanomaly is known as red weakness whereas Protanopia as red blindness (can’t see red), Deuteranomaly is green weakness and Deuteranopia is green blindness. Some other ones are Tritanomaly (blue weakness), Tritanopia (blue blindness), monochromacy (can only see blue) the most common one, Red-Green Colourblindness and Achromatopsia (total color blindness). Donald McIntyre concludes that the types of color blindnesses branch out from the basic Protan, Deutan and

Miracle of Christ Healing the Blind by El Greco and

...Compare and Contrast Essay about Miracle of Christ Healing the Blind by EL Greco and Denial of St. Peter by Caravaggio. Miracle of Christ Healing the Blind by El Greco and Denial of St. Peter by Caravaggio are both oil paintings depicting biblical events from the New Testament. The expressive components of both compositions reflect two different artistic styles conveying profound religious and spiritual content. El Greco’s painting encompasses the hallmarks of High Renaissance masters such as solidly rendered figures, dazzling colors, deep spatial recession and Roman architecture. Caravaggio’s dramatic use of light and shadow and meticulous attention to poses and gestures of his subjects are emblematic of the naturalistic realism of the Baroque period. The elaborate architectural setting of El Greco’s canvas with its deep linear perspective is filled with groupings of figures in the foreground. The figures, although realistically depicted and covered with body conforming drapery, appear elongated. Their gestures, facial expressions and twisted postures create a sense of movement, commotion, and reverence evoked by the mystical event of healing the blindness. The group of people on the right directs the gaze of the viewer to the figure of the blind man being healed by Jesus, and then it goes to the man on the left, turned backwards, with his finger pointing up. Just as the act of healing the blindness carries a symbolic meaning of the revelation of faith his gesture might...

John Howard Griffin Accomplishments

...children flee to England and survive the massacre that was going on. Risking his own and his family safety, he was committed to make a change for benefit of others. While serving in the United States Army, Griffin developed blindness and slowly lost his sight. He overcame the disability by continuing to work. He taught Piano lessons, wrote essays, and succeeded in his personal life by marrying one of his students and having four kids with her. Griffin was able to cure his blindness and his sight returned, as well as a different perspective on things after all that he had suffered. The experiment was so unusual that Griffin was doubting if he should tell anybody, besides his family, about it. He wished to see what it feels like to be on the other side of the coin. His goal to see what it feels like to be under constant pressure just because of his skin color, to see how people treat him with hatred and disgrace just because he was different, was unexpectedly harsh. In order to do so, he had to disguise himself or somehow make himself one of the blacks. He went to see a doctor to get his skin changed to black, and was successful in getting what he wanted. He was appointed to get ultraviolet treatments and take oral medication in order to keep the skin color dark. Griffin’s first claim that even though southern United States was segregated it was really a tolerant and peaceful towards the blacks was soon changed, and he was facing the consequences. His rights were taken away and...

Waiting to Exhale

...the forced sense of solidarity that I am assigned, the voice that always whispers to me when one of “us” appears intelligent: “Yes, these authors made us look like we had some sense! Look how analytical they sounded!” But why on earth do I have to feel like that in this marvelous, post racial society? After reading, I noticed that despite the year tacked on to the assigned readings, the content barely changed. From Dubois (1903) to Wingfield and Feagin (2012), we are still acknowledging the same woes that a society assigns particular groups of people. We are still attempting to come up with dire solutions in hopes that everyone will begin to “get along” with one another. But most of all, because of this…People of color are still waiting to exhale. In this essay, there will be two parts: Firstly, a general analysis of the assigned literature for this week. In this compartment of my paper, I will analyze extracted points from the readings thematically as it directly relates to certain points in the “Critical Race: An Introduction” excerpt. Here, I will also be giving a respectful critique of Dubois’ postulations in the “Souls of Black Folk.” Secondly I will critique Allport’s (1954) contact hypothesis that was discussed in Hewstone and Swart (2011). Introduction of Critical Race Theory (CRT) Before I analyze the literature, I think it would be wise to give a brief definition and explanation of Critical Race Theory in general. Delgado and Stefancic (2006) offered a pretty...

Ignorance Is Not Bliss

...Ignorance is Not Bliss Cathedral, written by Raymond Carver, is a short fiction essay with the narrator as the real protagonist that goes through a significant transformation. The author’s choice of point of view as well as, the theme and symbolism shown in Cathedral provide evidence to support the protagonist’s epiphany of overcoming his own prejudices. An important theme includes ignorance and understanding and the main symbol of the story is the cathedral itself. These components of the story are important in bringing out the narrator’s epiphany, where he comes to accept people for how they are and realize that he is not superior to someone who has an impairment. Carver chose first person as the point of view for this story. First person narrators are characters who tell the story from the perspective of “I” or “We”. This point of view gives the reader a chance to experience the story how the narrator sees and understands the world. In Cathedral, our narrator speaks in short, chopped sentences in the beginning. This shows the reader that he is lacking self-awareness, arrogant, and/or insecure. The narrator only sees Robert as a blind man, from the start. Throughout the story as the narrator gets to know Robert better, he becomes more descriptive with his sentences and his structure is not as choppy. This is important in showing his change of traits. This demonstrates to the readers that the narrator grows from ignorant to more open-minded and accepting, especially of...

Social Policy

...Essay 1 Our nation pursues the ideal that what we look like or where we come from should not determine the benefits or burdens that we bear in our society. Unfortunately, for African Americans, one of the largest minority groups within the United States, this is not a reality. In fact, life has been altered from the moment their lives began as an individual of color. Today, many people tend to remember the victories of African Americans that include abolition of slavery, desegregation, the civil rights movement, and the right to vote before women. People tend to forget the centuries of ugly racism, oppression and violence. The times of slavery, Jim Crow laws, lynching and segregation along with the hardship of having no political voice. Many disregard that for every social policy throughout history with what appeared to be an open door, just became another obstacle for Blacks and step up for Whites. Social policies and government programs have neglected and shortchanged African Americans for decades. Today, African Americans continue to face economic, social and health disparities within society when compared to its white counterparts. African Americans are struggling with unemployment and poverty. According to Fletcher (2013) in 2012, the black unemployment rate was 14.0 percent, 2.1 times the white unemployment rate (6.6 percent). This rate is higher than the average national unemployment rate of 13.1 percent. For those African Americans who are employed, many are unable...

Diseases and Causes

...Color blindness or color vision deficiency is the inability or decreased ability to see color, or perceive color differences, under lighting conditions when color vision is not normally impaired. "Color blind" is a term of art; there is no actual blindness but there is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve Muscular dystrophy (MD) is a group of muscle diseasesthat weaken the musculoskeletal system and hamper locomotion.[1][2] Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells andtissue.[3] Blood disorders can lead to poor blood clotting and continuous bleeding. The disorders can result from defects in the blood vessels or from abnormalities in the blood itself, such as in blood clotting factors or in platelets. Ichthyosis (plural ichthyoses) is a heterogeneous family of at least 28,[1] generalized, mostly genetic skindisorders. All types of ichthyosis have dry, thickened, scaly or flaky skin.[1] In many types there is cracked skin,[2] which is said to resemble the scales on a fish; the word ichthyosis comes from the Ancient Greek ιχθύς (ichthys), meaning "fish.

Cosmetic Animal Testing

...Ethics Issue: Back in 1933 there was a cosmetic product that was in the market called Lash Lure. This product was a mascara product that many women were using on their eyelashes to make the look longer and bolder. Lash Lure had contained p-phenylenediamine, which was an untested chemical that proved to be harmful to the customers using it. The p-phenylenediamine caused horrible blisters, abscesses, and ulcers on the face, eyelids, and eyes of the consumers who used Lash Lure, and it led to blindness for some. In one instance, the ulcers were so severe that a woman developed a bacterial infection and died. This incident and others like it led the United States Congress to pass the Food, Drug, and Cosmetic (FD&C) Act of 1938. This law gave the FDA regulatory authority over cosmetic products, and companies began to test products and ingredients on animals in an effort to assure safety for consumers. The FDA “urges cosmetic manufacturers to conduct whatever tests are appropriate to establish that their cosmetics are safe”, but “does not specifically mandate animal testing for cosmetic safety.” The issue that is being raised is it ethical to harm an animal for the sake of marketing a new cosmetic product. Facts: Every year, an estimated 70 million animals are maimed or killed for cosmetic testing in the US alone, and nearly $12 billion taxpayer dollars are spent yearly on the practice. Labs that use mice, rats, birds, reptiles and amphibians are exempted from the minimal protections...

...HUM101 Humanities are the study of the different cultural aspect of man, his frailties in life and how these can be improved. Also means understanding man and his affairs rather than just a prescribed unchangeable body of accepted facts and theories. * It comes from Latin word “Humanus” which means- human, culture, refined. * It has various connotation: depending on political, social, economic, artistic, and cultural forces * Refers to a loosely defined group of cultural subject area. Dictum of the Greek philosopher Protagoras “Man is the measure of all things, ‘meaning that the humanities uplift the dignity and values of man and his tendencies.” Culture is the disparity between man and animal; thus to be cultured is to possess refinement in taste and manners and these include speech, knowledge, belief, arts and technologies. Arts enhance daily experience and they are linked to the very quality of life. The word art encompasses meanings, including ability, process and product.

Gulliver Disillusioned: Is Multiculturalism Dead in the Twenty-First Century?

...Gulliver Disillusioned: Is Multiculturalism Dead in the Twenty-First Century? On the 17th October 2010, Angela Merkel, chancellor of Germany, delivered a speech at a youth conference in Potsdam where she proclaimed that multiculturalism has “utterly failed” (Siebold, Reuters UK). This dire statement was pronounced in the midst of a German society torn by cultural tension between Germans and Muslim immigrants. In theory, a society that embraces multiculturalism is one in which two or more cultures coexist whilst harboring mutual respect for the other’s values and lifestyles and upholding a common national identity (Parekh 6). Multiculturalism implicitly assumes cultural equality, the notion that no culture is superior to another. The idea that cultural differences should be encouraged and protected is currently embraced by many Western political thinkers. The twenty-first century is an era of unprecedented globalization and cultural diffusion. However, the mingling of different cultures is often followed by disastrous consequences as seen in the turbulent political situation in Germany (Siebold, Reuters UK). Although Jonathan Swift wrote his travel satire Gulliver’s Travels in an age when multicultural societies had yet to emerge (indeed, cultural imperialism was the zeitgeist of the eighteenth century, an idea quite antithetical to multiculturalism), the cultural clash that Swift’s protagonist Lemuel Gulliver experiences with the foreign peoples he comes into contact with and...

Allegory of the Cave Paper

...The Allegory of the Cave is Plato's explanation of the education of the soul toward enlightenment. He sees it as what happens when someone is educated to the level of philosopher. He contends that they must "go back into the cave" or return to the everyday world of politics, greed and power struggles. The Allegory also attacks people who rely upon or are slaves to their senses. The chains that bind the prisoners are the senses. The fun of the allegory is to try to put all the details of the cave into your interpretation. In other words, what are the models the guards carry? the fire? the struggle out of the cave? the sunlight? the shadows on the cave wall? Socrates, in Book VII of The Republic, just after the allegory told us that the cave was our world and the fire was our sun. He said the path of the prisoner was our soul's ascent to knowledge or enlightenment. He equated our world of sight with the intellect's world of opinion. Both were at the bottom of the ladder of knowledge. Our world of sight allows us to "see" things that are not real, such as parallel lines and perfect circles. He calls this higher understanding the world "abstract Reality" or the Intelligeble world. He equates this abstract reality with the knowledge that comes from reasoning and finally understanding. On the physical side, our world of sight, the stages of growth are first recognition of images (the shadows on the cave wall) then the recognition of objects (the models the guards carry) To understand...
