Essay About Blindness

Speech About Color Blindness
Color blindness is the inability to see certain colors or certain shades of those colors. An unlucky
few are unable to perceive any colors other than black or white, but the vast majority of people
suffering from color blindness struggle with only a few colors, so the condition may more
accurately be described as "color vision deficiency".
Color blindness is most common in males and it is known that 1 in 12 men suffer from the
condition, although there is speculation that a significant percentage of the male population may
have some sort of color vision deficiency without even realizing it. An estimated 1 in every 200
women are affected by color blindness, which makes for a total of 300 million color blind people
across the world.

Victims of deuteranomaly see most colors, although they aren't quite as bright or comprehensive
as the colors seen by somebody with normal vision. Sufferers of protanopia are able to see most
shades of yellow and blue without issue, but colors like green and red come across as slightly
faded. Tritanopia limits one's vision to just a couple of shades of green and yellow, but thankfully
occurs in only 0.0001% of men and

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

Blindness Essay
The term blindness implies total or
partial loss of vision involving both eyes. The exact
level of vision defined as blindness, however,
varies in different countries because of differing
legal or social requirements. In the United States,
blindness is defined as unimprovable vision of
20/200 (6/60) or worse. This means that an
individual is generally considered blind who, even
with the use of ordinary eyeglasses, can see no
better at 20 ft (6 m) than a person with normal
vision can see at 200 ft (60 m). On the other hand,
the World Health Organization (WHO) Program
Advisory Group on the Prevention of Blindness
lists the vision level suggested as blindness as a
visual acuity of less than 10/200 (3/60), which is
twice as...show more content...
Thus in developing countries in tropical
areas, the number of blind persons may reach at
least 21 million (using the WHO definition). This
high figure is due to the massive prevalence of
such eye diseases as TRACHOMA,

onchocerciasis (RIVER BLINDNESS), and the
NUTRITION–DEFICIENCY DISEASES
keratomalacia and xerophthalmia. In addition, few
eye doctors are present in such regions to treat
CATARACT or accidental eye injuries. In other
developing countries where eye care is not easily
available and the presence of untreated cataract
and undetected GLAUCOMA is also critical, the
number of blind persons may reach 5.5 million. In
developed countries with advanced medical
services, on the other hand, most curable
blindness is treated. Thus although many persons
may have vision problems, the exact number of
blind individuals may be less than 2 million. The
main causes of blindness in such countries are
age–related cataract, glaucoma, DIABETES, and
macular degeneration (see EYE DISEASES). In
the United States about 1 million cataracts are
removed each year and vision improved with
either an intraocular plastic lens, a contact corneal
lens, or a cataract glass. Several million Americans
are also being treated for glaucoma, which if
caught in its early stages can usually be dealt with
by medication or surgery. PAUL HENKIND,

Sense Of Blindness
HEIGHTENED SENSES IN THE BLIND
We as human beings utilize the five senses to process information about our surroundings. These
senses help keep us safe. For example, we use our sense of touch to avoid picking up a hot pan,
while our senses of smell and taste prevent us from cooking any rotten food in the pan. Our sense of
sight allows us to see an oncoming train, while our sense of sound makes it possible to hear the
train's horn.
Unfortunately, some people are born without the sense of sight, and many others may lose the
sense at some point in their lives for various reasons. It is estimated that 1.3 million people in the
United States are legally blind, and of the 1.3 million, only 1% are born without the sense of sight
(National Federation of the Blind, 2017).
Although not having the sense of sight can be devastating, studies have been conducted proving a
person's remaining senses can be heightened over those of individuals with normal vision.
The length of time a person experiences without their sense of sight seems to impact the
enhancement of their other senses. Therefore, we will see a trend in the following studies where
participants who are born blind or became blind early in life will often be categorized separately,
outperforming "sighted individuals," or people with normal vision.
The first study involved eight men with early–onset blindness and sixteen sighted men in the control
group (Cuevas, Plaza, Rombaux, Collignon, De Volder, & Renier, 2010). The purpose

Throughout the novel Invisible Man, Ralph Ellison works with many different images of
blindness and impaired vision and how it relates to perception. These images prove to be
fascinating pieces of symbolism that enhance the themes of impression and vision within the novel.
From the beginning of the novel when the narrator is blindfolded during the battle royal to the end
where Brother Jack's false eye pops out, images of sight and blindness add to the meaning of many
scenes and characters. In many of these situations the characters inability to see outwardly often
directly parallels their inability to perceive inwardly what is going on in the world around them.
Characters like Homer A. Barbee and Brother Jack believe they are all knowing...show more

It should also be noted that the narrator never gives a name to the Founder or mentions Booker T.
Washington. The author uses this to signify their invisibility in the real world. Related to the
veiling Founder is a man who avows to the Founder's extraordinary principles and astonishing
contributions to the black community. Homer A. Barbee speaks about the Founder to students at
the college and makes his life sound like a verse out of the Bible. He speaks of how the Founder
"miraculously recovered" (119) as a baby, his incredible journey through the Underground Railroad,
and the seemingly magnificent message he spread to the people: Ah, those days of ceaseless travel,
those youthful days, those springtime days; fertile, blossomy, sun–filled days of promise. Ah, yes,
those indescribably glorious days, in which the Founder was building the dream not only here in
this then barren valley, but hither and yonder throughout the land, instilling the dream in the
hearts of the people (124). Barbee makes the Founder sound like Jesus leading a flock of sheep.
Barbee's speech was so powerful and moving that he made the narrator "see the vision" (133), and
only after Barbee was done speaking did the narrator realize that he was blind. This actual
blindness is symbolic of Barbee praising a man that he sees fit, yet the Founder is not truly worthy
of Barbee's praises. Barbee can only see the Founder through blind eyes, in which

Essay about Blindness in Invisible Man
Many people wonder what it would be like if they were to be invisible; stealthily walking around,
eavesdropping on conversations, and living as if nothing is of their concern. Invisible Man, by
Ralph Ellison, is centred on an unnamed fictional character who believes himself to be, indeed,
invisible to the rest of the world. He is not invisible in the physical sense, but socially and
intellectually. As the book develops, readers are able to experience an authentic recollection of
what life is as a black man living in a white man's world. This man wants to achieve so much, but is
severely limited by the colour of his skin. This novel, which has become a classic, addresses the
themes of blindness in fighting stereotypes and predestined...show more content...
Bledsoe, the college president, to become employed and presumably come back south to school –
neither of which happens. In an attempt to display the surrounding area of the campus he
mistakenly ends up driving Mr. Norton, a well respected man that has donated significant
amounts of money to the college, into an housing area of poor black sharecroppers that had
previously been slave quarters. So, Mr. Bledsoe scolds him for the incident and expresses the
unexpected views, to the invisible man, to keep things the way they are so that he, Mr. Bledsoe,
will remain in his powerful position. Generally, people of a certain group would encourage
growth of power in society of their group. Instead of doing that however, Mr. Bledsoe says, "I's
big and black and I say 'Yes, suh' as loudly as any burrhead when it's convenient, but I'm still the
king down here. . . . The only ones I even pretend to please are big white folk, and even those I
control more than they control me. . . . That's my life, telling white folk how to think about the
things I know about. . . . It's a nasty deal and I don't always like it myself. . . . But I've made my
place in it and I'll have every Negro in the country hanging on tree limbs by morning if it means
staying where I am" (Ellison 145–146). Ultimately, this view means tearing down his own race in

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

Saramago uses the depiction of misfortune to allow the blind to act so inhumanely in this novel.
There is the perception that "humanity will manage to live without eyes, but then it will cease to be
humanity", which is what the doctors wife perceives on her repentance of her murderous revenge on
the thief. Saramago also perceives that "revenge is just human" (256).
The doctor's wife at least shows her respect of her own dignity due to her compunction of her
"humanitarian motives" (256) and by "weighing up her consequences" (78) unlike most of the
others. But then again, there is no humanity within the blind. This logic is what backs up the group
of seven's constant cease of indignation. The doctor's wife symbolizes hope and dignity considering
her engagement of leadership on the seven strangers. One's experience affects its quality;
representing the doctors wife's deliverance of faith to the others. And in the environment they were
in, eyes were the best technique for experience. She "must stay, it's [her] duty"; that motive of hope
maintained the other's treatment of they're own dignity (252). The protagonist's gender is another
metaphor for the doctor's wife's quality, especially when recollecting on the "masculine logic"
involved in this novel (168).
"All steps of indignity" endured by the main group in Blindness are usually based on a life or death

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

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).

Thesis: Blindness is a problem because most cases of blindness can be avoided, it's increasing
tremendously, technology isn't made for the blind, learning has to be altered, and it's expensive.
First Body Paragraph–
Blindness is a problem because most of the time it can't be avoided. Although most people think
that most cases of blindness can be avoided, but that's not true. This is proven in an article posted

Second Body Paragraph–
Blindness is a problem because blindness cases are suppose to increase tremendously. In a research
led by Rohit Varma, M.D., director of the University of Southern California's Roski Eye Institute.
"The number of people with visual impairment or blindness in the United States is expected to double
to more than 8 million by 2050." Also found in the research led by Rohit Varma, M.D., they found
"the number of people with legal blindness will increase by 21 percent each decade to 2 million
by 2050." The number of blindness cases are suppose to rise extremely. More and more people are
going to be blind, which means more and more of the population is going to be affected by
blindness. There are going to be tons of people affected by blindness, making blindness are big
problem. Although most people don't believe that blindness is increasing, they actually believe that
blindness is decreasing. But that's not true because Varma was able to show that blindness is in fact
actually increasing through research.
Along with cases increasing, blindness is also a problem because technology is hard for blind
people to use.
Third Body Paragraph–
Blindness is a problem because technology is getting harder for blind people to use. In an article
posted by Kate Beck, a certified ophthalmic technician, she stated that "Technology poses a

Essay on Color Blindness
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–hue disk–matching test, measure one's ability to match colors. This can be
useful when determines one's degree of anomalous chromatism.

Essay on Jose Saramago's Blindness
When defining the word blindness, it can be interpreted in various ways. Either it can be explained
as sightless, or it can be carefully deciphered as having a more complex in–depth analysis. In the
novel Blindness, Jose Saramago depicts and demonstrates how in an instant your right to see can be
taken in an instant. However, in this novel, blindness is metaphorically related to 'seeing' the truth
beyond our own bias opinions.
Saramago's novel clearly illustrates themes that describe the importance of the awareness of others,
in terms of feeling oppressed by fear, lack of trust, dehumanization, and segregation. He describes in
full detail the importance of the government's involvement in the lives of the blind victims, which

For instance, "Hispanic women are more likely to be dissatisfied if they feel they have been treated
badly by providers and staff and if they do not trust doctors" (Guendelman, Wagner 118). If the
patient does not feel a sense of hospitality and see a welcoming smile, it discourages the patient to
visit the physician because they feel they are not getting the right medical attention, and tend to be
sicker. In addition, "the sicker individual risk exposure to more insults, and this leads them to pull
back from the health care system" (119). In a physician/ patient relationship there needs to be a
balance between actually caring and giving your patients the attention and satisfaction that they
deserve. Some physicians take advantage of their patient's vulnerability of being sick by pushing
them aside, and worrying more about the fastest way to make money. However, the physician then
loses another patient because of greed.
Saramago represents trust in a very similar manor, yet instead he describes a man who is suddenly
overcome with a "white blindness" while stopped at a red light. He explains how an onlooker has
offered to drive the blind man home, and takes advantage of the frantic man's situation by stealing
his car, "that good soul, has taken our car [...] He took advantage of your confusion and distressed

then I woke up outside this place." He slows to catch his breath. "It looked like a...a school, it was
that guy, Gareth and five other ones. They were eating my leg right in front of me, like it was
nothing. All proud like they had it all figured out." Rick strokes his beard. "Did they have Daryl and

Carl. He already knows what I'm thinking. "I'm sure it's not because of you, maybe they had to get
away from some walkers." He whispers into my ear from behind. I nod as he slowly strokes my hair.

This can also be the thesis for the occupants on the boat in Life of Pi; such a long and hopeless
endurement leads to the destruction of reason and dignity. Relating more on main group of
blindness; there is the thought that "what is right and what is wrong are simply different ways of
understanding relationships with others"; compensating for the group's down spiral of dignity. That
kind of understanding seemed to be essential in preserving the group's sanity.
Sanity is a huge factor when dealing with ones actions, and when considering human value. The
surveillance of the doctor's wife and the group effort to keep strong preserved such sanity. As for the
others, the psychological realm they were trapped in seemed to betray such sanity. Reflecting back
on the main group, the length of the period in which they were all confined in was definitely a
contribution to the durability of the group.
The cruel confinement placed on the blind from the government manifestly shows the degration of
humans, especially when it comes to the impaired judgment enforced by the ignorant. Survival and
selfishness erased all reason and worthiness. In the short story of Somni in Cloud Atlas, we reflect
on the greed of "Papa John's" for the degration of lives. In the Luisa Rey short story, money
overwhelms the value of everything else. The military's motives in Blindness also illustrates
unhealthy dignity. One of the

Advantages And Disadvantages Of Blindness
I.Affecting an estimated 10 million people in the US alone, blindness is a disorder of the eyes
and the visual centers of the brain, resulting in cloudy to no vision. Even though it is believed that
the blind see nothing but darkness, only about three percent of the blind report seeing nothing.
Being able to see movement and light is what 97% if the blind report seeing. Even though they are
able to see light and movement, they are not able to see color. This is what they are able to see
with their eyes, however some are also able to with their "mind's eye". Utilizing other senses and
technology such as cortical implants, the blind population is able to create images in their "mind's
eye".

Blindness In David Foster's The Blind Man
Foster introduces the blind man in chapter 22 in his novel. He mentions how physical blindness is
important when brought into a story. He says it starts to make the other characters change and
"behave differently". He also says how when a blind person is introduced something important is "at
stake" and the author is trying to emphasize the levels of sight beyond the physical one. He sort of
shows how the blindness of a character can also be quite ironic. Those who are blind are able to see
and those who are able to see are blind. This could be applied to many things such as the blind
knowing the certain truth while the sighted are doubtful and don't really know the truth. Foster also
describes blindness as a metaphor for failing. The blind...show more content...
I have recently watched the Television show Daredevil and the main character, Matt Murdock, is
actually blind. This show is very relatable to what Foster talks about. His blindness is revealed
right at the beginning of the show and we notice that he became blind as a child. This is
important because now we know that the character wasn't just blinded as an adult but instead he
really began his life blind minus a few years. His blindness actually helps him throughout the
story and when introduced the audience just knows that "something important must be at
stake"(ccii). . It heightened his senses and therefore became a superhero because of it. He was
able to hear everything around him, even if it is the quietest thing in the world. The irony shows
when he becomes a lawyer. His business partner, Foggy, was with him in a court as lawyers one
day and they were defending someone. In a court of law nobody really knows who is telling the
actual truth but Matt is able to hear the heartbeat of the jury and witness. He notices that whenever
the heartbeat is at a faster pace they are lying or not saying something. This shows the irony
because Matt is able to see through people and their lies while Foggy and the rest of the court who
aren't blind do not have this ability. Foster is true to his word when saying that blind characters are
very important to the

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
