...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....

...matter where you are in the United States, when a word like racism is thrown around, its subject and all related material are bound to cause controversy and disagreements. Color blindness, or racial blindness is one of these issues associated with racial advantages or opportunities. It is a sociological term meant to disregard when discussing participation in something. My view on this issue is con-color blindness for several reasons. First of all, the United States is still not seen as truly equal when offering some opportunities. Also, there are not distinctions or classifications for people to base any kind of statistics on. For these and other reason, color blindness used nationally would not be successful in this country. Affirmative action is one case of con-color blindness. This is a method of offering opportunities to certain people according to race, gender, or religion that are misrepresented in the process. In other words, they are not getting an equal opportunity for jobs or education. I believe this helps open up chances for everyone that would normally not offered to them. It creates more of a broad spectrum in the fields of employment and education as everyone is more represented in these fields. Most Americans are split on this issue and with the introduction of racial color blindness; it has created more controversy on the subject of equality. The role of education would be changed dramatically if we did not recognize race. Several scholarships and...

...(Apfelbaum et al. (2012) - Color Blindness) 1. What were the 3 most important or interesting things you learned from this article? 1) Race is being addressed in schools to be accepted; however emphasizing that race doesn’t matter is having the opposite effect as early as age 10. 2) Dominant groups as Whites believe they are underprivileged because of policies that assist Blacks, which shows how important racial blindness is. I find this result interesting because I do not believe that Whites are disadvantaged by such policies. 3) Multiculturalism is an approach where group differences are openly discussed and examined to avoid color blindness. Todd and Galinsky (2011) found that people exposed to a multicultural message would express better understanding of other people by...

...John dalton John Dalton was born in September 5,1766 in Eaglesfield in Cumberland, and died July 27, 1844 in manchester england. Dalton and his family lived in a small country house. His family had been Quakers since 1690. Quakers where members of a society of friends. John had a brother named Mary and a brother named Charles, when he was born his brother was twelve years old and his sister was two years old. Dalton's birth was not recorded, so when he grew up older he asked one of his relatives and got an answer which was his birthday. His parents were honest people and good workers. His dad Joseph had land he had inherited were Dalton and his brother Charles help out with the crop. His mother Deborah Greenup homespun textile Dalton's sister help her too. John Dalton's family were poor but "although they were never hungry they were poor" Dalton was lucky he was a Quaker , other boys received little or no education, but as Quakers Dalton received a fair education at the closest Quaker school . For Dalton it was an achievement going to school since in those times only one out of two-hundred and fifteen people could read. John Dalton went to the Quaker school at Pardshaw Hall. Dalton was quick when it came to studies and in mathematical problems he was good and seem to be tireless of them. John Fletcher was Dalton's teacher, he was a smart man who didn't use a rod to hammer in learning to Dalton, he was to provide Dalton with a excellent back-round...

...olVirtual Genetics Lab: The Inheritance of Color Blindness Worksheet Learning Goal: To explore the inheritance pattern of color blindness in humans. Prerequisite Knowledge: Before beginning this lab, you should be familiar with these concepts: * the definition of sex-linked genes, and examples of sex-linked genes in humans and other organisms * how the inheritance pattern of sex-linked genes differs from that of autosomal genes * the use of Punnett squares to understand patterns of inheritance Introduction: The gene that codes for red-green color blindness, the most common form of color blindness in humans, is found on the X chromosome. One in 12 males is color blind. In females, however, color blindness affects only about 1 in 200. Why is there such a difference? In this lab activity, you will act as a genetic counselor and help parents determine their likelihood of having color-blind children. You will also use this information to understand why males are more likely than females to be color blind. Part A Couple 1 comes into your office. The husband has normal vision; the wife is heterozygous for the color-blindness allele. Enter the Virtual Genetics Lab Room by clicking the button. Then, follow the Lab Procedure. Lab Procedure 1.

...Color is a complex experience for humans because we all experience it in different ways. For instance, those who are color-blind will not experience color in nearly the same way as those who are not, and I feel sure that there are gradations of how people experience color from the extreme of color-blindness to full visualization of color nuances. Even within the concept of color, there are three different categories to consider: hue, value, and intensity. To have a full-on discussion of the use of color in art, you have to be conversant about the basic color (hue), value (the amount of black or white added to the basic color), and intensity (the amount of basic color the artist chooses to use in his/her medium). Even then, you can go further and discuss the impact of opacity, translucency, and transparency on color. Color is a convoluted experience for humans because we all experience it in disparate ways. For instance, those who are color-blind will not experience color in nearly the alike method as those who are not, and I sense sure that there are gradations of how people experience color from the great of color-blindness to maximum visualization of color nuances. Even inside the believed of color, there are three disparate groups to consider: hue, worth, and intensity. To have a full-on discussion of the use of color in fine art, you have to be familiar concerning the frank color (hue), worth (the number of black or white added to the frank color), and intensity (the number...

...Color Blind or Color Brave? Carrie Rawdan SS236-05 Professor Burnett February, 24th, 2015 The story of Mellody Hobson “Color blind or Color brave” is a powerful speech about the reality of current day racism. She choose to share her brilliant ideas and life experiences by giving a speech on TED. Her stories of racism and her triumph of becoming one of two black woman running a fortune 500 company are intriguing. Mellody Hobson delivers a powerful speech that touches the heart and encourages the mind to decide if we are Color blind or Color brave”. “TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages” (TED, 2014). This is an amazing opportunity for people to share their views, life experience, and intelligence in a global community setting. Mellody Hobson, the chairwoman for DreamWorks, started her speech on TED with a full audience. She spoke of a story supporting a friend at a predominantly white meeting and was mistaken for the kitchen help. “This experience made her ask herself and friend, is this a good enough reason why we need more racial diversity in the U.S Senate” (Hobson Mellody, 2014)? The daughter of a single mother and five other siblings, Mellody said she was taught at a very young age the realness of the world from her mother. One day after a birthday party, Mellody’s mother did not ask the normal question...

...Achromatopsia from research conducted mostly online. All of the research conducted explains the device on how it is used and what it is used for. It also shows how the sounds are conducted so the people using the eyeborg can understand it. Neil Harbisson's Eyeborg Barcelona based artist, Neil Harbisson was born with a condition called Achromatopsia which means that he was born color-blind. He has described himself as a cyborgist and colorologist. With the help of a new technological device that is attached to the back of his skull can translate color to sound. Harbisson can hear the color of sound through audible frequencies through this device in which he calls an "eyeborg". Harbisson has used the term sonochromatism (or sonochromatopsia) to define his new condition. He explains that "achromatopsia can no longer define his condition because achromatopsics cannot perceive nor distinguish colors. He also explains that synesthesia does not define his condition accurately because the relation between color and sound varies depending on each person, whereas sonochromatopsia is an extra sense that relates color to sound objectively and equally to everyone" (Harbisson, 2012). The idea for the device came about when he was attending Dartmouth College of Arts in England, where Harbisson met Adam Montandon who was giving a lecture on cybernetics and they [came together] to start developing the eyeborg project (Disaster, 2012). The device, called an eyeborg, comes out of the back of...

...must wear bifocals or trifocals to obtain the best vision at every distance. However, these problems are minor irritations compared to the loss of vision caused by a common agerelated disorder. Painlessly and insidiously, age-related macular degeneration (AMD) affects an estimated 10 million Americans.' It's the most common cause of vision loss and blindness in people over 65, and it can affect people at younger ages as well.' The risk of developing AMD steadily increases with age. People in their 50s bave about a 2% chance of developing it, while the risk rises to nearly 30% in those over age 75.^ Every three minutes, another case of AMD is diagnosed in the US.^ Each year, 200,000 people with AMD lose all central vision in one or both eyes.' More people than ever before will be forced to live with AMD as the baby boomer generation continues to grow older. This article reviews the anatomy and function of the normal retina. It also identifies tbe risk factors for AMD and its causes, as well as its diagnosis and treatment. A diagnosis of AMD means a significant decrease in vision, and, in some cases, complete blindness. Because patients face important concerns related to their everyday activities, methods of addressing those issues will be discussed. Normal Vision For a person to see properly, light must pass through the cornea, pupil, and the lens. Then it must be focused onto the retina, the innermost layer of tissue at the back of the eye. The surface of...

...Visual Impairment Introduction Vision challenge or impairment is when a person’s degree of seeing is very low and the affected person requires assistance in order to carry out daily routine. Significantly, for one to qualify as visually impaired there must be prove that a person cannot undertake duties by himself without necessary assistance. For a person to qualify as a visually challenged, there must be a prove that the affected eyes cannot be conventionally treated. Visual challenge cannot be corrected by surgery, refractive measures neither by medication and that is why it is termed as visual impairment. The most rampart causes of visual challenge are trauma, degenerative or congenital means and a variety of diseases. In the society, blindness is the term that is preferably used to describe a visually impaired per son. Low eyesight is generally revealed when the affected person cannot view a normal distance and walk by himself (Algozzine, 2006). The degree of impairment can also be revealed when a person cannot read some normal writings. This is to say that even with the assistance of contact magnifying glasses or even eyeglasses the victim cannot reveal the writings on a normal newspaper (Bailey & Hall, 1990). Hyperopic impairment is accrued with inability person to see objects in a close distance. Myopic impairment is quite the opposite of hyperopic whereby a victim cannot identify objects at close distance. All these vision challenges greatly obscure the affected person...

...Cataracts are the leading cause of blindness around the world and most common in people over the age of 40.1,2 There are more than 22 million Americans that are affected by cataracts.1 Cataracts are a clouding of lens in the eyes that can eventually cause vision loss.2 Cataracts can happen in either or both eyes. The eye’s lenses works just like a camera lens.1 The purpose of the lens is to focus light onto the retina to create clear vision, and to adjusts the eye’s focus.1 The lens consists of water and proteins.1 The proteins in the lens are arranged in a certain way that allows light to pass through the lens and to let the lens keep clear.1 When people start to age, the proteins in the lens start to clump up and start to cloud certain areas of the lens.1 This causes vision loss. There are different factors that can cause cataracts. The factors are diabetes, ultraviolet radiation, hypertension, obesity, smoking, previous eye surgery, family history, high myopia, significant alcohol consumption, and previous eye injury.1...

...Research Paper 1: Paradigm Shift Argus II Retinal Prosthesis System is created by Second Sight design for people that are suffering from blindness. It starts with an epiretinal prosthesis implant which is an implant placed on top of the retina. Also attach is an antenna, electronics case, and an electrode array. Those parts are than connected to glasses, cable, and video processing unit. How it works is a small camera in the glasses capture an image than is processed by VPU that is attached to the belt. It than sends the instruction back through the cable to the glasses. They are than wirelessly transmitted to the antenna in the implant. Which go to the electrode array that creates a small pulse of electricity. These pulses stimulate functioning cells bypassing the damage photoreceptor. They then send visual information through the optical nerve to the brain. The patient is than able to see pattern of light. One impact is the ability to see anything as a person with blindness. They being able to see an image that is not just darkness. To see a world in not just one color but in a variety of colors. Second to be able to see motion in front of them. Moving object would be able to be seen. To see what the things making sound are and what are they. Third impact is what it would do to their self-confidence. It would boost it immensely for they would not have to rely on another being to do something. To be able to walk outside and not have to rely on a walking stick, a person...

...Conditions Related to the Eye and Blindness Michael A. Allen Jackson State University Abstract Conditions related to the eye and blindness is very common. There are many disease of the eye. Many of these diseases can cause a lot of harm. There are five main points that will be discussed they are age-related macular degeneration, retinitis pigmentosa, retinopathy, visual impairment in higher learning, and social support for the visually impaired. Macular degeneration often damages central vision and is prevalent in people age 60 and over with rare cases of people fewer than 50. Retinitis Pigmentosa is common among families; it’s not always related to hereditary factors. Retinopathy is a common problem for people with diabetes where retinal blood vessels break down and affect vision. People with visual impairments who are in higher learning are very common now days and accommodations are set up for persons. Social support for people who are visually impaired is key factors to helping those individuals have a normal and productive life. Introduction There are many eye conditions. They are listed as followed. Lazy Eye or Amblyopia is a very common condition. Usually present early in childhood, lazy eye can be corrected if caught early. Learn what you can do to correct this eye condition before it becomes severe. Aphakia is a condition where the lens of the eye is missing. It can greatly decrease your vision acuity and cause other problems if not treated. Astigmatism...
