Color Blindless

Color blindness is the inability to distinguish particular colors. It is generally an inherited trait, but can result from a chemical imbalance or eye injury. There are three primary colors. They are red, blue, and yellow. All other colors are the results of different combinations of primarycolors. Special visual cells, called cones, are respon–sible for our ability to see color. People with normal vision have three different types of cones, each responsible for a different primary color. The absence of particular cones causes the absence of particular colors. This can be one cause of color blindness. There are four types of color...show more content... These people tend to confuse blue, yellow, and gray, but not red and green. Normal vision is called trichromatism. Most color blind people have a version of trichro–matism called anomalous trichromatism. People with this condition can see the same colors as people with normal vision, but not as well. For example, many people with this common form of color blindness are "green– weak". This means, they see green, but to see the same color normal people see when green and yellow is mixed, more green must be added. "Green–weak" and "red–weak" are the most prevalent forms of anomalous trichromatism. The "blue– weak" form is rare. Color blindness can be tested in a variety of ways. The Hardy–Rand–Rittler and Ishihara tests indicate both the type of degree of color blindness. In these tests, a variety of shapes, letters, and numbers lie in a jumbled mess of dots. The dots vary in both color and intensity, which cam–ouflage the shapes. A person's ability to detect such shapes directly corresponds with their degree of color blindness. Other tests, such as the Holmgren yarn–matching test, and the Farnsworth–Munsell 100

People in their everyday lives use their eye sight to help them function with everything they do. We never usually stop and think about the consequences and changes we would have to make if we were to one day lose our vision. Some people question about how we could lose our sight. There are many different ways this might happen. It could be by accident, with something injuring the eye. It could also be Cataracts, this could effect vision since the lens in the eye becomes foggy and eventually over time vision could be totally impaired. Glaucoma could be another cause, this is when fluids in the eye build up and cause too much pressure in the eye; damaging important nerves. There are many other diseases and illnesses that could cause blindness. Once you go blind there is a very slim chance that you will get your vision back.

There is lots of treatment for blindness in general that has saved people. The treatment for blindness is close to the same treatment for cancer one way that can fix blindness is killing the red blood cells in the eye (79). Other ways would be using angiogenesis inhibitors which are drugs that which grows new blood cells in the eye to help circulate blood through the eye (79). These are some of many different types of treatment they use Radiation therapy, electronic implants, Stem cell therapy, cell transplants, and retinal tissue transplants (79). There are many professionals in the study of blindness that help find cures and help. These are just some of the many doctors ophthalmologists, optometrists, and opticians (66). Charles started to lose his sight at the age of four or five, and was completely blind by the age of seven, apparently as a result of glaucoma (52).

Blindness Essay

More than one million Americans suffer from blindness, a severe vision impairment (Marcovitz 6). Blindness can be caused from an accident or a disease (10). One victim of blindness, Stevie Wonder, has overcome it by making music and performing. His positive outlook on life helps him achieve many things (79). Being blind means a person is sightless or is unable to distinguish dark colors from light colors, but they can still overcome it (Dahl). Eye diseases, like glaucoma and cataracts, can be causes of blindness. Symptoms of glaucoma may include headaches, pain in the eyes, or blurry vision (Marcovitz...show more content... In future technology, surgeries, such as implant surgery and transplantation of retinal tissue may help blind people (Marcovitz 73, 76). In 1831 Perkins School for the Blind was the first school to help blind people read, communicate, and speak. Later, Louis Braille discovered Braille, a code using dots and dashes for the alphabet (34). When rubbing fingers across it, the markings indicate certain numbers or letters (33). Guide dogs can also aid the blind when walking around so they know where to go (45). Groups such as the American Foundation for the Blind and National Federation of the Blind help provide assistance and new laws for blind people and their families (41). Preventing eye disease and blindness is important. Wearing protective eyewear, and practicing healthy habits like exercising and eating well (Marcovitz 68) can prevent blindness. Getting regular eye exams (Worth) can also help detect it earlier as well (Dahl). There are many people worldwide and in America who are blind. About fifty million people around the world (Dahl) and over one million Americans (Marcovitz 6) are totally blind (Dahl). Therefore, it is essential to take steps to prevent blindness. Stevie Wonder, one of the many affected by blindness, was born on May 13, 1950 in Saginaw, Michigan where his love for music began. Wonder was born prematurely and has been blind since infancy because the blood vessels in his eyes were not fully developed (Marcovitz 6) but, he believes

Blind Obedience

While sitting in church on Sunday going through the same motions of every Sunday, my son leans over to ask, "Why do we have to stand up for this prayer?" My response "because we are supposed to".

Reading "The Children's Story" by James Clavell, made me think a little more about this question that I had no answer for. A person needs to be able to explain why he does what he does. Children are innocent and unknowing; they are like a blank piece of paper waiting to be filled up with drawings and ideas. This book shows just how easy it is to mold a child.

It uses a classroom of children facing a major change in their lives as the setting. The story moves quickly and the characters are only...show more content...

In the story, the "old" teacher doesn't always remember the students names, has never had children of her own, and her memories of all her classes led to a "legion" of faces of which none stood out. In contrast, the "new" teacher memorizes in advance all the students names and birthdays. That is enough to impress any child.

Although the children in the story resist at first, it doesn't take this "new" teacher long to convince them to do away with the Pledge of Allegiance and to rip up the flag. Not a single child could explain why they say the pledge or what they were pledging allegiance to. When the students initially showed curiosity on the topic, they were rebuffed by the "old" teacher. The message was clear, you are not here to think you are here to learn. It made me wonder, if I were to walk into a classroom today, how many children would know why they were saying the Pledge of Allegiance? I didn't know as a child why we said this every morning, it was just something I had to do. The new teacher is very subversive, and after dispatching the Pledge of Allegiance, she attacks religion and the flag as other symbols that may not be worthy of reverence. All the good things in life come from the new leaders. The children believe her, because they have been programmed to believe that their leaders are always right and must be obeyed. It only took her 23 minutes to convert enemies of the leader into good citizens!

Have you ever been completely oblivious to a situation that is taking place right behind your back? You think that everything is going just fine in your perfect little world. You have everything planned out and it seems to be working out right on track. Then all of a sudden you discover something so devastating that it changes your whole life, and everything you worked at for nearly a year. This is exactly how I felt when I found out that my girlfriend had been cheating on me. I felt like everything I had worked so hard to establish had been gone, and that I was all alone.

My life was going along perfectly. I was in the middle of soccer season. My team was destined for the DistrictChampionship, and already...show more content...

We were always having little fights and just not agreeing on a lot of things anymore for some reason. I cannot really say that I am an expert on relationships, so I just figured that it was just a rough spot in our relationship. My girlfriend had just started a new job, and I felt she might have been a little stressed by it seeing how she was working a lot more and our time together was cut down. Over the weeks our relationships slowly started to get worse and worse. I could not for the life of me figure out why all of a sudden things just were not working out. It seemed as if my girlfriend just stopped caring. We would go on for days with out seeing each other or even talking.

I would call to talk to her, and there would be no answer. Messages I would leave would never be returned. I just kept thinking to myself that she was just busy with her work, and being a junior stressed out about college.

Well, to my surprise, my girlfriend did not just stop caring about me. She had already started caring about someone else. Sadly, I had found out from one of my friends, and one of my girlfriends close friends, that she had been cheating on me with a co–worker, for almost a month now. After confronting her about this with my friend, she had admitted that it was all true. Wow, I could not

Deaf Blindness

Most people assume that a deaf blind child is someone who is not able to hear or see. "Our country's special educational law defines deaf–blindness as the combination of the visual and hearing impairment" ("Deaf Blindness"). These two impairments make the person lose his or her communication skills, developmental and educational needs. The National Consortium on Deaf–Blindness observes that the key feature of deaf–blindness is that the "combination of losses limits access to auditory and visual information" ("Deaf Blindness"). Through this research I was able to discover the origin of deaf blindness and explore about this disability.

All the children with deaf blindness differ from each other. They are all unique in their own way. The amount of visual and auditory loss varies in all individuals. The sensory input sometimes gets damaged but for some other individuals it won't get damaged. The vision and hearing may be lost from birth but for some others it takes time and eventually gets lost. "Either or both losses may be gradual or immediate and may not be accompanied by the loss of other body functions" (Mcllnnes and Treffry). Deaf blind people will face symptoms that are combined. There will be symptoms based on loss of hearing and loss of vision. There are different types of conditions that may lead to deaf blindness. Congenial Rubella Syndrome and Usher Syndrome are common conditions that lead an individual to be a deaf blind. loss of a little vision and hearing is very common among older people. It's just a sign of aging. This can rarely lead to be a deaf blind person (Schneider, O'Toole, and Fletcher).

Based on the statistics 45000 to 50000 people in US are deaf–blind. "According to the 2007 National Deaf–Blind Child Count, over 10,000 are children under the age of 21"("Deaf Blindness"). The word deaf Blindness is sometimes misunderstood by people. They think it means a person who cannot hear

Reflection Of Blindness

An individual is not merely defined by the situations that they find themselves in, but rather how they react during these tragic moments. The eminent novel, Blindness, by Jose Saramago, is an iconic story that illustrates a country enduring a pandemic that causes the inhabitants to acquire a type of blindness where they only see white. The unfortunate citizens who fall ill to the white blindness find themselve quarantined in an abandoned mental hospital where havoc inevitably ensues. A significant character that demonstrates the notion that you are defined by your actions is the doctor's wife as she was originally a very timid and kind character who then endured an atrocious situation and became very malicious. Whereas the girl with the dark glasses is an individual who was first presented as extremely selfish but later developed into an extremely selfless individual. To continue, the young boy was a character who valued his family for the entire novel and found it very difficult to live without them, yet due to his circumstances, he was able to adapt. The responses that the characters within Blindness by Jose Saramago have when presented in the face of adversity is what truly defines those particular characters. It is often through atrocious situations where individuals face a shift in their values and inevitably discover a new aspect of themselves– whether it be malice, selflessness or carelessness. The deepest and darkest aspects of oneself often only shine through when an individual undergoes a horrendous situation. During the commencement of the novel Blindness, the doctor's wife was originally one of the kindest and caring characters that Saramago mentions. This notion is evident when her husband– the doctor– was being taken away to be quarantined. During this chapter, the doctor was being seized by military officials as he was struck with the white blindness and needed to be quarantined. Although the doctor's wife was not blind she told the military officials that she was also ill in order to stay by her husband's side. When the couple arrived at the mental hospital, the doctor asked his wife why she risked falling ill to the atrocious disease by going to the hospital. She calmly replied, "my love... I'm

Good vision is essential for safely driving commercial or owner operator trucks. However, even with a healthy pair of eyes with 20/20 vision, you can't always count on them to see everything on the road. That's because the external world can interfere with your vision, or your brain may fail to properly process the signals sent by the eyes. In short, you can't see something unless sufficient light from the object reaches your eyes, your eyes correctly convert the light into nerve signals, and your brain processes, or "makes sense" of the signals. If any one of these critical steps don't occur, you become blind to whatever you're looking at.

Assuming your eyes work fine, here are four ways you can fail to see what's out there on the road:

Selective Attention...show more content...

In order to cope with this information overload, it filters out irrelevant visual inputs. What's left over is what you see. This selective attention leaves you blind to the filtered signals. For example, if your entire focus at an intersection is finding traffic gaps to exploit, you can become blind to pedestrians on crosswalks. Another way of putting this is that you only see what you're looking for.

Inattention Blindness

This occurs to people who mentally multitask. The brain's limited capacity means that it's poor at doing multiple things requiring brain power. An example of this is holding a cell phone conversation while driving. If the conversation requires thinking or imagining things, objects on the road become invisible because the brain lacks the capacity to carry on the conversation and also see all the traffic, signs, potholes, people, and other activity on the road. Up to [fifty percent] of what's on the road can vanish even when your eyes are looking at the objects. This occurs even when your cell phone is hands free.

Being Blind And Blind People

Human beings take their senses for granted, especially their ability to see and hear. They are luxuries one has, but does not notice until they no longer have them. People take these senses for granted because they don't realize what it is like to be blind or deaf. They don't realize what life is without seeing color or knowing what people look like. They don't realize what life is without hearing people talk, birds chirping, or the wind howling. Helen Keller, who was blind and deaf, adapted to her challenges of not being able to read or write, to becoming an author, political activist, and lecturer. This serves as an example for how a blind and deaf person should try to live. That doesn't mean that it wasn't challenging for her to live her daily life and she did not have all the opportunities as a person that has all of their major senses. It isn't easy to live without the capacity to see and hear, for those people who don't have the capacity, it is another struggle and another accomplishment to live their lives with these struggles of being blind and deaf.

People see the colors of unique flowers, they see the sky go from sunny to midnight blue, and they see different colors of clothing. They judge what they should wear, take a picture of, and buy for their houses depending on the color of the object. People living without eyesight don't handle these situations in the same way. Losing eyesight is awful because it becomes difficult to do tasks. For example, when a Get more content

Color Blindness Essay

Color Blindness

Many people refer to problems with one's ability to see color as color blindness, however, unless a person can't see any color at all, color vision problems should be called by another term. Common terms are abnormal color vision, color deficiency and color vision confusion. Females maybe be effected by color blindness, but usually they are just carriers. Males are more often affected. About 8% of males and 0.5% of females are effected by color blindness. Although color blindness may be a result of another eye disorder, the majority of color blind cases are hereditary and present at birth. The retina, is a complex nerve system which converts light energy into electrical energy that is then transmitted...show more content...

This is the rarest form of color blindness. This is when no colors can be seen at all. The color receptors are almost completely gone in this form, however, the white and black receptors remain intact. However, this condition is often misdiagnosed without proper testing. There are three basic types of color blindness: deuteranopia, protanopia and tritanopia. Deuteranopia is a condition in which people have trouble dealing with green. These people are one of the largest groups of color blind people. Very often, these people also have a problem with red. These people can often distinguish red or green when with other colors, but when it is by itself, it is very difficult. Many people will just see it as white. Protanopia are those seem to need an abnormal amount of red or have no sense of red color vision. Often, people will see bold red as black or nonexistent. Some people may see red–orange as brown and yellow–green as brown. In other words, neither red or green can often be distinguished for sure. Tritanopia are those who have trouble distinguishing blue and yellow. This disorder is much less common than the red–green colorblindness, and is usually acquired, not received through heredity. These people may see both blue and yellow as white. They may even see mint green or pink as an equal to light blue. Red color blindness is the most common. This is when the red color receptors are nonexistent. These Get more content

Blind People Myths

Now, there are many myths that people hold about blind people. Some of the myths that the narrator in "Cathedral' holds are, "This blind man, feature this, he was wearing a full beard! A beard on a blind man! Too much to say" (Cite). Much to contrary belief, blind people's hair still grows the same as anyone else's hair as long as they don't have any other disease that would interfere with hair growth. Another myth that our narrator thinks is when he says, "But he didn't use a cane and he didn't wear dark glasses. I'd always thought dark glasses were a must for the blind" (Cite). The reality is, not all blind people carry a cane or wear dark glasses. However, there are many reasons why most blind people choose to. Blind people, just like any other person needs to protect their eyes from UV sun rays, and because they are blind they cannot tell where they are looking at the sun or not, therefore the sunglasses help in this way. Another reason a blind person might wear sunglasses is for aesthetic reasons, as was read in the story the narrator wished that Robert would wear the dark sunglasses, he says: Fact was. I wished he had a pair. At first glance, his eyes looked like anyone else's eyes. But if you looked close, there was something different about them. Too much white in the iris, for one thing, and the pupils seemed to move around in the sockets without his knowing it or being able to stop it (Cite). With wearing sunglasses, it can make other people at ease (Ashish).

What does it mean when one is described as being blind? Many people would answer that it can be defined as a person who lacks the gift of sight either as a cause of an accident or nature. However, in the case of Native Son, the scenario is different because the characters are blind as a result of a history entailing the common practice of mistreatment. Bigger Thomas is blind in his perception of white society and its reality. In the same sense, the white society is blind of blacks and their lifestyle. What each perceives of the other is actually false. Richard Wright argues, through the character of Max, that Mary Dalton's murder was the effect of a cause that has been occurring for decades. The cause is the maltreatment of blacks and...show more content...

This is the theme of blindness that Wright tries to express through his characters. Mr. Dalton is also the owner of the South Side Real Estate Company, which charges blacks outrageous prices for apartments that don't deserve such a high rent. The same types of rooms are charged a significantly less amount in the other side of town only because they are situated in all white neighborhoods. Bigger's family suffers financial problem because their income is low and rents are high. So indirectly, people like the Dalton's are the root of the problems faced by blacks in Chicago. Mrs. Dalton also faces the same the problem of blindness but presents it in a more literal manner. When Bigger goes for his job interview and is introduced to Mrs. Dalton, he is told that "she has a very deep interest in colored people." The ironic part is that she is blind and, as a result, cannot see blacks as people but she is still interested in them and tries to help them. In Book II, Mrs. Dalton is worried that her daughter is missing and asks questions. However, she hesitates to ask Bigger questions because she IS embarrassed. "After all, he was black and she was white. She would be ashamed to let him think that something was so wrong in her family that she has to ask him, a black servant, about it." Hence, this proves that Mrs. Dalton didn't even look upon Bigger as an equal person. Not because she was literally blind but because she was mentally blind. This can be related to
