Partial Blindness Research Paper

When damage to certain regions of the brain occurs, conditions may develop where one is able to register visual information but incapable to distinguish anything (Anderson, 2009). Consequently, difficulties with visual impairments can include an inability within the brain to interpret and or process visual information (Anderson, 2009). Thus, visual perception impairments or disorders typically refer to the inability to make sense of information received through sight (the eyes) (Weiten, 1998). One such visual perception disorder is visual agnosia.

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.

According to the Oxford Dictionary, the definition of blind is “unable to see; sightless” (Definition of Blind in English, 2015). However, I do not like to be put in such a box. I define blindness as merely a heightening of other senses. What do you think of when you hear the word sight? More than likely you think of shapes, colors, and objects. My idea of sight consists of many senses; smell, touch, sounds, those are the things that I “see” with. How about the word blind; what do you think of then? The most common relation to the word blind is disabled; however, we are a very abled people. Even though I carry a cane among my person I get through my daily life just as any other able-bodied human being (Question 1).

A medical definition of vision impairment is a sine qua non that prohibits 20/20 vision in one or both eyes (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; Vision Australia, 2015; Webster & Roe, 1998). Examples of vision impairment include, cataracts, which has the lens inside the eye increasingly cloudy; albinism, which is passed down genetically affecting clear vision and causes sensitivity to bright light; optic nerve damage, which affects field of vision as those nerves controlling vision are disrupted; macular degeneration, where parts of the retina that control colour and fine details are affected; retinitis pigmentosa, which is an ongoing reduction of the field of vision available and nystagmus, where the eye flickers involuntary (Bowman, Bowman, Dutton & Royal National Institute for the Blind, 2001; American Foundation for the Blind, 2015; Vision Australia, 2015 ; Baton Rouge Regional Eye Bank, 2015). John suffers from retinitis

John Dalton has been known to have discovered his own colour blindness in the year of 1794, seeing pink as blue and scarlet as green. The vitreous humor is known as a gel that can fill a space that is in-between the lens and retina of the eyeball, it’s also known as vitreous body. There are around 1 in 12 man and 1 out of 200 women that colour blindness affects in their everyday life, there are also different types of colour blindness that affects many such as Deuteranomaly or Protanomaly are also known as red-green where they find it difficult to see reds, greens, browns and oranges. Monochromatic which is seeing no colour at all. In a person’s eye there are three colours that make up all the colours that show in someone that is colour blind they have a faulty hue of colour and

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

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.

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.

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.

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

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).

Colorblindness can refer to a variety of color vision deficiencies ranging from difficulty in distinguishing certain colors to complete absence of color vision. Colorblindness can have some disadvantages that go along with not being able to see color. However, there are also some advantages to the absence of color.

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).
