Partial Blindness Research Paper

When one thinks of being blind, they think of someone who literally can not see, but one can also be blind by lacking perception or awareness. People who have sight and yet are blind is clearly seen in the book, To Kill a Mockingbird. To Kill a Mockingbird is a story based in the 1930’s when racial issues are heavily present. In the novel, To Kill a Mockingbird, and throughout history, people or groups of people have existed who can literally see the world around them, and yet are blind to the truth; but, as seen in the novel, some of these people’s eyes can be opened to the truth either by empathy or experiences.

Many people make an assumption they are not blind to life itself whether ignorance plays a part or pride. In Cathedral by Raymond Carver, it describes a few myths that society has portrayed and opinions of the visual impaired. The main focus is getting to know the person before drawing a conclusion. Its not fair to anyone to be neglected whether you are visual impaired or have the functionality of what is considered to be a normal human being.

Change blindness occurs when the observer does not noticed any changes in their visual field.

I enjoyed your forum post this week, it was very informative. I find color blindness to be an odd but interesting visual phenomenon. I had a good friend that I served with in the military and he was color blind. We could always tell when he was in trouble with his wife, because he would be wearing the wrong color undershirt. Two of the main colors that he was unable to distinguish were green and brown, I believe that would mean that he suffered from Protanopia color blindness. You selected great potentially dangerous situations. As I was reading your examples, I thought of a similar situation. Along with not being able to distinguish the color of traffic lights, I believe that some traffic signs would be hard to decipher as well.

The common thing in affected people is that they have damage in the part of the retina handling central visioni. The thing that is different in affected people is the amount of useful eyesight. It will depend on the lighting, how tired they are, and how experienced they are at using the remaining sight. Moreover, what varies for affected people is the size of the central loss of vision. Some affected people may see a dark shadow in the center; greyish blurring, or even brightly coloured spots. ("LHON

One of the highlights from this article is a developed pair of sunglasses that is known to temporarily "fix" color blindness, or allow the individual to see the world in colors they have not had the privilege to do before, for as long as they wear the glasses. For the author, these glasses enabled him to see "breathtaking" sunsets, but he doesn't think he'd miss them.

Soothing effect on the nervous system, applied to those who have lost understanding and knowledge, sick headache, for those who hide their worries behind a brave face, for those under work-related tension and problems between employer and employee. For stress incontinence.

There's something about the mindset of high school students that seems to make them think they're unassailable. If you walk down a high school hallway and look around, you see the faces of kids that carry themselves as though they're invincible and ready to take on whatever comes at them. The reality is, almost all of those faces are concealing suffering that's consuming them.

Being colorblind can have many disadvantages like not being able to see which color the traffic light is on or not being able to find things that you have dropped in the grass, but being color blind can also come with advantages too. Being color blind can help people spot certain things that look the same color to other people.

Some forms of colorblindness can be caused by chronic illness, accidents, medications, chemicals, and even age. Illnesses such as Alzheimer’s, Parkinson’s, and leukemia can cause colorblindness (Acquired Colour Vision Defects). Accidents causing damage to the eye or brain, and medications like antibiotics and anti-tuberculosis drugs can cause vision impairment (Acquired Colour Vision Defects). While it is possible for an individual to become colorblind though any of the previously stated means, it is more common for someone to have colorblindness genetically. Although, if a person becomes colorblind due to an injury or other cause, it is not genetic and therefore will not be passed

Although color blindness does not always have a big effect on the lives of people, at times, it can be a problem. Whether it is at home, school, or work, a colorblind person may face certain challenges that those who have normal color vision aren't aware of (Living with Colour Vision Deficiency). First take school for instance. Many educational materials are color-coded to help guide the learning process; however, the students who are color blind (especially when they aren't diagnosed with color blindness yet) find themselves in trouble during these situations. Another example where there can be problems at school when being colorblind can occur for students with red-green color blindness because they "may also have difficulty reading a green

Colorblind people do most everything normally, but there are a few troubling situations that can occur. For example, some may have trouble telling whether produce is ripe, seeing whether meat is properly cooked, and noticing skin rashes or sunburn. Depending on the person, they might have trouble being able to distinguish the colors of traffic lights, especially in dim light. Also, most states don't require color vision testing in schools. This may cause some difficulty to some students when they are looking at color-coded assignments. Whether it be that the teacher does not know that a student is colorblind, or the student themselves may not even know.

Throughout World War II, it was found that analysis reports of aerial photographs were more accurate when at least one member of the group of analyzers was colorblind. Color blindness is a vision deficiency disorder, in which the eye becomes more or less sensitive to color. This is the result of the malfunctioning, or lack, of special cone cells in the eye. Although color blindness may seem beneficial in a situation similar to war, most people with color blindness find it to be a disruption to everyday activities, and sometimes even a danger to themselves or people around them. There are many significantly differentiating types of color blindness that can be characterized with varying symptoms; however, many people do not even realize they have a vision deficiency disorder, which is why color blindness is difficult to diagnose. Overall, many humans carry a disorder that affects their vision of the world, but few have been diagnosed, and even fewer choose to accept help despite the diagnosis of their disorder (Colour Blind Awareness, Color Blindness).

There are even apps/settings that will change colors to accommodate color blind people who have issues distinguishing colors. Most of these apps/settings are found on mobile devices, TVs, videogames, etc. Also, particular contact lenses and glasses have been crafted to accommodate a patient who has a color deficiency in an attempt to lessen the effects of colorblindness, and to give color deficient people an opportunity to see colors that other people see (AAO).
