Nuclear Sclerosis Case Study Visual Decrease

Nuclear Sclerosis Case Study
A 67 year old female Caucasian patient comes in to the clinic complaining of decreased vision,
affecting the left eye more than the right. She is being treated for hypertension, cholesterol, and
diabetes. Her distance vision is 20/25 OD and 20/40 OS and her near vision is 20/25 OD and 20/50
OS. Her prescription was found to be –11.00–1.00X180 OD and –13.50–1.50X015 OS, which is
classified as high myopia. A 1+ nuclear sclerosis was found in the right eye. A 2+ nuclear sclerosis
and a paracentral subcapsular cataract were found in the left eye. Due to these findings, it was
determined that glasses could not fully fix the patients vision. This lead to a referral to a retinal
specialist and a cataract surgeon. No other abnormalities were noted on the initial examination. The
patient then came back when the cataract surgery was performed on the left eye and the visual acuity
improved to 20/25 at distance and 20/25– at near OS. All things concerning the surgery seemed
normal for a day after the IOL placement. Six months later, the ... Show more content on

The main way light is obstructed on its way to the retinal is by a cataract in the lens, which is the
case in this patient. These can form two major ways: ultraviolet light damage and aging. Ultraviolet
light damage leads to an abundance of free radicals. These free radicals act on the crystalline
proteins and cause them to clump together, creating a cataract.[2] Another way cataracts are formed
is by the natural process of aging. Concentrations of alpha crystallins fall off with age with leads the
other subtypes to aggregate and form scleroses (cataracts).[3] This is what is leading to the glare that
the patient sees at night. The cataract is scattering the light entering her eye and leading to blur on
the retina. Both of these could have contributed to the cataracts in this patient due to her being over
65 and due to her age naturally being exposed to more

Winter Symbolism In Literature Essay
When you think of winter what do you usually think about? I think about the freezing temperatures,
the ice, and the snow. However, in literature winter can be symbolic of many things. The dark,
sadness, old age, and death are just some of the things winter can symbolize in literature. The songs
"California dreamin'" by the Mamas and Papas and "A hazy shade of winter" by Simon and
Garfunkel are both about winter but mean very different things. Foster's How to Read Literature
Like a Professor will also be referenced in order to help show the meanings of these pieces.
California dreaming is a very simple and straightforward song;. It has three short verses and a
chorus that repeats a couple of times. " California dreamin' on such a winter's day" is repeated
throughout the song. This is the main essence of the song. The narrator is telling us that he likes the
warm and sunny days of California more than the cold harsh winter. Throughout this song we learn
of other things that the narrator dislikes which are gray skies and brown leaves. These signify the
arrival of winter which saddens the narrator. There's also a deeper meaning that can be figured out
with the help of Foster's work. In his book he tells us that the cold often can symbolize sadness and
that warm often symbolizes happiness. One of the many possible meanings that the mamas and
papas could be trying to convey is that it isn't easy to be happy. In the song the narrator arrives at a
church and is going to stay. Even though he isn't very happy he would rather be in the church than in
the cold as shown in the next verse where he starts to complain about the cold again. We can learn
from this message to be thankful for what we have even though it isn't what we want because it
could always be worse. In " A Hazy Shade of Winter" by Simon and Garfunkel the narrator sends a
clear message that he does not like the arrival of winter. When you hear the song you can tell how
much he doesn't like the winter anytime anything related to it is said. His voice becomes low, dull
and lifeless. The way he sings tries to makes you associate sadness with the winter. To the narrator
the winter may be sad because it is cold but if we look deeper into the song we

Humans have a unique and wonderful device in how one sees. The eye and brain work together to
turn the world into visual data one's brain can understand and use. There are some eye conditions
that inhibit the sight or the recognition of the shapes one sees. Research continues to overcome these
conditions as well as to further understand the biochemical reaction that gives humans the sight and

According to current research there are about 800,000 ganglion cells in the human optic nerve (J.R.
Anderson, 2009,pg. 35). The ganglion cells are where the first encoding of the visual information
happens. Encoding is the process of recognizing the information and changing it into something
one's brains can understand and store. Each ganglion cell is dedicated to encoding information from
a specific part of the retina. The optic nerve goes then to the visual cortex and the information enters
the brain cells. There are two types of cells that are subcortical, or below the cortex; the lateral
geniculate nucleus and the superior colliculus. The lateral geniculate nucleus is responsible for
understanding details and recognizing objects. The superior colliculus is responsible for
understanding where objects are located spatially. This collection of cells working together is called
the "what–where" distinction. The division of labor continues, as the information is further
processes. The "what" information travels to the temporal cortex, the "where" information travels to
the parietal regions of the brain.
The brain identifies what it sees in a series of steps. The brain makes a feature map of the eye
breaking the visual field into sections. Information collected in a particular section of the visual field
will always be sent to the

PHYSICS PROJECT
TO STUDY THE OPTICAL LENS OF A HUMAN EYE
Eyes are organs that detect light, and convert it to electro–chemical impulses in neurons. The
simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye
is a complex optical system which collects light from the surrounding environment; regulates its
intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an
image; converts this image into a set of electrical signals; and transmits these signals to the brain,
through complex neural pathways that connect the eye, via the optic nerve, to the visual cortex and
other areas of the brain. Eyes with resolving power have come in ten fundamentally different ...

Possessing detailed hyperspectral color vision, the Mantis shrimp has been reported to have the
world's most complex color vision system.[8] Trilobites, which are now extinct, had unique
compound eyes. They used clear calcite crystals to form the lenses of their eyes. In this, they differ
from most other arthropods, which have soft eyes. The number of lenses in such an eye varied,
however: some trilobites had only one, and some had thousands of lenses in one eye.
In contrast to compound eyes, simple eyes are those that have a single lens. For example, jumping
spiders have a large pair of simple eyes with a narrow field of view, supported by an array of other,
smaller eyes for peripheral vision. Some insect larvae, like caterpillars, have a different type of
simple eye (stemmata) which gives a rough image. Some of the simplest eyes, called ocelli, can be
found in animals like some of the snails, which cannot actually "see" in the normal sense. They do
have photosensitive cells, but no lens and no other means of projecting an image onto these cells.
They can distinguish between light and dark, but no more. This enables snails to keep out of direct
sunlight. In organisms dwelling near deep–sea vents, compound eyes have been secondarily
simplified and adapted to spot the infra–red light produced by the hot vents–in this way the

Paper 5 – Anatomy/Physiology of the Special Senses (vision/auditory)
Color Perception
Visual processing in our brain cannot be done without actual vision. The anatomy of the eye is
carefully arranged with all the parts that assist our vision in an optimal way. A layer of connective
tissue called the sclera surrounds the eyeball. Underneath it is the choroid, which is rich in blood
vessels that supply the eye. Attached to this layer is the lens by cililary muscles. The lens focus light
to the retina and the amount of light entering is controlled by pupil dilation or constriction. Pupil
dilation and constriction is regulated by the iris of the eye which consist of two layers of smooth
muscle layers that contract or constrict to increase or decrease the diameter of the pupil respectively.
The retina is the inner most layer of the eye. It the main site of photoreceptors that convert light
energy into electrical energy where the information gets sent to the brain and is what we perceive as
vision. (Marieb, 2014)
Two types of photoreceptors can be found in the retina, the rods and cones. Rods are mainly
responsible for scoptic vision thus mostly reactive in dim lighting. Cones are responsible for
photopicvision, which provides color under bright light conditions. When it is dark out, only the
rods are active so you see monochromatic vision. There are three types of cones S, M and L that
respond to different wavelengths. Each rod and cone contains two parts the

In the year 2009, there were 39.6 million adults who were 65 years or older. Baby Boomers made up

expected to almost double making 72.9 million adults who are aged 65 years or older making up for
an astounding 19% of the world's population. All in all, 5% of the world's population are in nursing

"...Lighting can and will make a greater difference in the success of a healthcare setting than any
other single feature except the healthcare itself" (Brawley, 2008, Page, 5).
Light levels in Nursing homes must be increased to make up for the loss of visual acuity that occurs
within the aging eye. In order to provide the needed amount of light for older adults, light levels
need to be raised, balancing of natural light and artificial light must occur, as well as the elimination
of glare. The elimination of glare is critical. As adults age, glare and reflection become real
problems and play key roles in contributing to agitation, confusion, and anger; this in turn, inhibits
activity and compromises safety (Brawley, 2006, Page 8).
When designing an elder care facility, designers and architects should be very conscious of the LRV
(Light Reflectance Values) within a space. LRV is a measurement taken of the usable light reflected
from a surface when illuminated (Wikipedia, 2013). For a more energy–efficient lighting solution,
ceiling should be placed at 9–10 feet high. In conglomeration to this, use of lighter more reflective
paint should be used in a ceiling so that at least 80% of the light is reflected back down to the
surface. (Brawley, 2008, Page 9). Flooring surfaces should reflect a minimum of 30–40% of light

What Makes This Catch The Eye?
This garment, inspired by nature, instantly grabs someone's attention. Instantly, someone can tell it
has many natural elements: the floral chest and leaf pattern. The garment is filled with various
textures and color that give it its calming, natural feel. The texture has natural elements of leafs and
flowers that are emphasized by the bold lines surrounding the element. It even has colors that
resemble wood with a pop of color from the flowers. With more thought, it seems as if it resembles
woodlands with a patch of colorful flowers. It seems as if it carries out it its purpose. It has a
woodland theme, looks unique, and has interesting textures. However, questions start to emerge.
What makes this catch the eye? Why is it interesting? How does it work so well? To determine this,
the garment must be broken down in the individual elements of design (texture, color, balance,
unity, shape, form, line, variety, form, proportion and scale, symmetry, and space) and evaluated.
The outfit itself primary in flat with only one primary area with actual texture: the upper torso. The
dress has long sleeves with an enlarged opening for the hands, giving it a classical sense. It is short,
only going a few inches above the knee for a freer and flowing look. This helps to create
bisymmetric balance, unify for the garment's form with the patterns, and texture on it. The tulle on
the neck and around the lines on the chest helps add the third dimension to the dress by being more

1. Differentiate between sensation and perception. Explain the importance of separating these
concepts.
The term sensation is used when referencing the process of sensing the environment through taste,
touch, sound, smell, and sight (Goldstein, 2014). Moreover, it is the process that occurs once the
sensory receptor experiences stimulation, which in turn produces nerve impulses that are sent to the
brain to be processed in its raw form, then perception comes into play (Goldstein, 2014). Perception
is used to describe the way people interpret these sensations and tries to make sense of everything
around them on a daily basis. Perception is the occurrences of the brain ... Show more content on

3. As we age or incur visual impairment, we may need brighter light when reading. Explain why this
is the case.
As a person ages, the constant need to accommodate when looking at nearby objects such as in
reading or doing close–up work becomes more difficult (Goldstein, 2014). The main reason a person
may experience the need for a brighter light when they get older is a result of a condition called
presbyopia, also referred to as "old eye" (Goldstein, 2014). Old eye describes when the distance of
the near point increases as a person ages. According to Goldstein (2014), "The near point for most
20–year–olds is at about 10 cm, but it increases to 14 cm by age 30, 22 cm at 40, and 100 cm at 60"
(p. 25). Generally, this change occurs because the lens hardens with age and the ciliary muscles in
the eye become weaker, causing great difficulty in vision when looking at objects in close range
(Goldstein, 2014).
4. You are shown a picture of an elephant. Explain how that stimulus is processed from the retina to
the visual cortex of the brain.
Focusing an image clearly onto the retina is the initial step in the process of vision, but although a
sharp image on the retina is essential for clear vision, a person does not see the picture on the retina.
Vision occurs not in the retina, but in the brain. Before the brain can create vision, the light on the
retina must activate the visual receptors in the retina by a two–element

The Reflection Of The Human Eye Work
How does the human eye work?
The cornea is clear and at the front of the eye. When light rays enter it, the cornea refracts it through
the pupil and then the iris. The iris controls how much light may pass through the pupil by
expanding or shrinking. Next, the light ray will enter the lens. This also refracts light by changing its
shape with the help of the ciliary muscles and the suspensory ligaments. The light will go through a
dense jelly–like tissue named the vitreous humour and eventually focused at the back of the eye onto
the retina. The retina is a light sensitive tissue and covered with rods and cones. These receptors will
capture the light ray and transform it into electrical impulses. They get sent off through the nerve
fibres, then the optic nerve, and then finally the brain. The picture given by the retina is upside down
so our brain will next turn it the right way up.
Our bodies have the capability to endure large scars but, a slight scar on the cornea can lead up to
our vision becoming impaired. The retina will process the light rays, into light impulses that need to
be transferred to the brain to create an image, which are focused on to them by the cornea. So, any
deep injures experienced by the cornea can lead to corneal scarring which would affect our vision.
Focusing on near and distant objects
People that have trouble focusing in near or a distant object is due the light rays entering their eyes
are unable to focus on the retina. This is a very common

metaphors, symbolism, imagery, and foreshadowing. The unique use of said literary devices enables
the story to strongly entice the reader's interest and spark high levels of curiosity. The vivid mental

the painter, Edgar Allen Poe.
The initial analysis will be that of the old man's eye. Mr. Poe uses very descriptive technique to
allow the reader to view the eye for themselves, there are no literal pictures within the pages of the

The previous paragraph explained the eye symbolizes misconception, but the structure of specific
sentences implies that the eye can indeed see even the most hidden of things. After the main
character dismembers the old man, he proceeds by removing three planks from the floor in order to
store the corpse underneath the floor, and in conclusion to this horrid act he states "I then replaced
the boards so cleverly, so cunningly, that no human eye – not even his – could have detected
anything wrong" (p.4, Angus). Such a statement implies that not only does the eye capable of
depleting vision and understanding, but the eye also has the ability to enhance perception and
amplify vision as well.
The eye is the center, the main attraction if u will, of this story. It is no wonder as to why the eye
symbolizes quite a handful of things. In addition to the symbols analyzed prior to this paragraph, the
symbolism of control is also used with the eye. The eye displays the "power" of controlling the
narrator's fluctuation in body temperature which is a result of controlling the narrator's mood and
level of fear. "Whenever it fell upon me, my blood ran cold; and so by degrees – very gradually – I
made up my mind to take the life of the old man, and thus rid myself

Colour Blindness : Color Blindness
All you need to know on colour blindness
In spite of the name, colour blindness isn't a form of blindness but a defect in the way that your eyes
interpret colour. With this particular problem, you'll find yourself having trouble when it comes to
telling the difference between certain colours such as blue and yellow or more commonly red and
green. Colour blindness, or colour vision deficiency as it's sometimes known, is inherited and tends
to affect more males than females. According to the Prevent Blindness America association, it's
estimated that roughly 8% of men and less than 1% of women have colour vision trouble. The red
and green colour deficiency is by far the most common form of colour blindness. The blue and

This will all depend greatly on the type of colour vision problem they have. If you've suddenly
developed a form of colour blindness despite previously having the ability to distinguish all colours
then we strongly advise you see an eye doctor immediately. A sudden or gradual loss of colour
vision could indicate any number of underlying health problems with cataracts being just one
example.
More often than not, colour blindness occurs as a result of light–sensitive cells within the retina
failing. They fail to respond properly to different varieties of wavelengths of light that ordinarily
would allow people to distinguish an array of different colours. Photoreceptors within the retina are
known as cones and rods with rods being more plentiful; there are approximately 100 million rods
within each human retina). Rods are also much more sensitive to light however they're incapable of
perceiving colour. There are roughly 6 to 7 million cones in the human retina and it's the cones that
are responsible for seeing colour. These photoreceptors are all located in the very central part of the
retina that's known as macula. The centre of the macula is known as the fovea, measuring a mere
0.3mm in diameter. It contains an extremely high concentration of cones, the highest concentration
within the retina in fact and it's this area of cones that are solely responsible for our most acute
colour vision. If colour blindness has been inherited, it's

Color And The Perception Of Color
Color and the Perception of Color
Cynthia Xu
Stoller Middle School
Perception. The ability to see, hear, or become aware of something through one of the five senses
(Kandel, Schwartz, & Jessell, 2000). In other words, it is the process of interpreting and organizing
sensory information. Perception must be understood according to figure–ground, similarity,
proximity, continuity, and other organizing principles. At work in the interpretation of sensory
stimuli are other perceptual phenomena such as perceptual constancy, a phenomenon which occurs
in the perception of size, shape, color, and brightness; depth perception, another phenomenon based
on binocular and monocular cues; and the perception of motion (Wood, 2008). One of the brain's
primary functions is to obtain biologically important information from the various sensory inputs.
The brain of a human is provided with sufficient information about a variety of things such as light,
sound, the atmosphere's chemical composition, temperature, and things such as head orientation,
limb position, the chemical composition of the bloodstream, among other things. Specialized
sensors project signals into the brain when they detect sensory modalities. Light–sensitive neurons
in the retina of the eye, vibration–sensitive neurons in the cochlea of the ear, along with the
pressure–sensitive neurons in the skin are all specialized receptor cells of which each sensory
system begins with. The axons of the sensory receptor

Love Should Grow Up Like An Wild Iris
Real Life Love Throughout "Love Should Grow up Like an Wild Iris in the Fields" Susan Griffin
provokes the readers to think twice about why they consistently enslave themselves with the burden
of daily monotony, instead of enjoying the simplicity of love. Griffin uses two metaphors in her
poem when describing love, as a flower, as well as the iris of an eye. Her comparisons are both
interesting as well as accurate. Love should be born and live in fields, just like wild flowers. Love
needs to be nurtured by water, with no concern about where and when the next rainfall will take
place. Love needs to allow nature to take its course and trust in the sustenance that its surrounding
provides. However, love refuses to take the easy path. Instead, love decides to live in kitchens
alongside irritated cooks, dirty walls and screaming infants with impatient mothers. Clearly, love
would be better off without concerns, growing in a field like an iris, patiently waiting for the next
rainfall. However, love chooses to exist in chaotic environments filled with discontent and discord.
In the first verse Griffin begins her poem by describing the flower in a field. Within the first few
lines, imagery is used in such a way that it creates a vivid picture for the reader. "Love should grow
up like a wild iris in the fields/ unexpected, after a terrible storm, opening a purple/ mouth to the
rain, with not a thought to the future/ ignorant of the grass and the graveyard of leaves/ around,

I run away from the ruins, the wind tousling my hair. The tears I had shed, dried away, leaving me
with a placid face. I had to make it back to camp before sundown. As I run, scouting for glass that
might cut through my threadbare shoes, I pull a small dagger from my dress pocket. Not my weapon
of choice, but when you're living like this, you don't have much of an option. The sky is filled with
dark, hazy clouds, that blot out the sun. Though, they cover things that I am much more worried
about. I feel a drop of water on my face and quicken my pace. It's possible for the monsters to come

The Evolution Of The Human Body
The evolution of the human body can be observed from studying the intermediates found in
ancestral organisms. Shubin proposes that every attribute that makes us human can be traced back to
a time that showcases its importance for survival. Every single trait in the human body has been
selected for through multiple mechanisms of evolution, natural selection being one of them. This
theory is intriguing because not long ago it was unheard of to relate humans to fish, amphibians,
reptiles, mammals, and birds. Every highly specialized characteristic such as balance, sight, smell,
and more began as an extremely simple mutational advantage. The complexity seems unfathomable
to many as to how the human body as been come to be, but everything can be explained logically
once scientists take a closer look at other organisms. Selective pressure is constantly promoting the
survival of advantages mutations and quickly removing disadvantageous traits. Organisms were not
designed to be what they are today but rather they underwent a lengthy experiment of trial and error.
The different environmental pressures have lead to a vast expansion of biodiversity, each organism
is best suited to fit their own niche. There is no "superior" organism since the outcome is that the
species is the best adapted to its environment over another species. Species always have a potential
niche and a realized niche where their specific advantageous traits were selected for to aid in their
survival. Specific

Pathophysiology Of Dementia And Alzheimer's Disease
Pathophysiology: Dementia Dementia, also known as Alzheimer's disease (AD), is a progressive,
chronic, and degenerative. 60% of dementia occurs in people over the age of 65. Dementia causes
loss of judgment, memory, change in personality, and visuospatial perception. Severe cognitive
impairment can occur over time, as well as physical deterioration and death. The brain changes in
size and weight as a person ages. There is also a narrowing of the gyri, enlargement of the
ventricles, and widening of the cerebral sulci. In AD, these changes are accelerated, causing issues
such as atrophy of the cerebral cortex and loss of cortical neurons. In addition, the pre–central gyrus
of the frontal lobe, superior temporal gyrus, hippocampus, and substantia nigra are all affected.
Changes in neurofibrillary tangles (tangled masses of fibrous tissue throughout the neurons) ,
amyloid–rich senile or neuritic plague (degenerating nerve terminals in the hippocampus which
contain proteins that form neurotoxic plague in the brain) and granulovascular degeneration can all
occur as well. Though the exact cause of AD is unknown, possible factors of cognitive impairment
in older adults include neurologic, cardiovascular, pulmonary, metabolic, psychological,
environmental causes, nutritional deficiencies, and drug toxicity. Signs & Symptoms: Alzheimer
Disease is staged based on symptoms. Early (Mild) or Stage I can last up to 4 years. Middle
(Moderate) or Stage II can last 2–3

Taking a Look at Astigmatism
Astigmatism is a flaw in the curve of the cornea (the front of the eye or the clear, round dome
covering the eye's iris and pupil). The cornea and lens are generally even and rounded equally in all
directions. This mechanism helps the eye to focus light emissions sharply against the retina at the
back of the eye. In the cornea of an average eye the lens focuses light waves on the retina. If the
cornea or lens isn't smooth and equally rounded the light waves will not be refracted properly. This
is stated as an inaccuracy in the refraction of light in the eye.
In an eye with astigmatism, images are fixated in the anterior of the eye, past the retina, producing
equally near and far–off images to seem hazy. This is the main symptom of astigmatism. Other
symptoms include; blurry or distorted vision at any distance, sensitivity to light, headaches and
locational migraines, excessive squinting (the person is constantly closing his/her eyes), or any type
of strain of the eye. The strain on the eye could occur when driving or reading for a prolonged
period of time. All of the following are impairments of perception caused by visual impairment;
Visual–Motor Integration (eye–hand, eye–foot, and eye–body coordination), Visual–Auditory
Integration (the ability to relate and associate what is seen and heard), Visual Memory (the ability to
remember and recall information that is seen), Visual Closure (the ability "to fill in the gaps" or
complete a visual picture based on seeing only

Analysis Of ' Construction Of The ' The Bluest Eye And...
In this literary criticism , "Construction of the 'Racial Identity' by Gaze and Blindness in The Bluest
Eye and Native Son", Md. Abdul Karim Ruman explains how the identity of African Americans are
constructed in The Bluest Eye, as well as the racial effect of this construction.
Ruman begins by defining some key terms, such as "gaze" and "panopticon". He looks at 'gaze' in
the cultural sense, not only defining it as "the desire of one person that constructs the identity of
another who is gazed", he explains through which means the gaze is implied and employed, in films,
posters, school, literature, media, newsreels, newspaper reports, consumer goods, advertising, and
pop culture. After defining the term 'gaze', Ruman explains the concept of the panopticon, created
by Michel Foucault. The panopticon is a type of model for a prison, in which the prison guard or
overseer is in the center of an array of open yards and prison cells. From any angle, the guard can
see, 'gaze', or 'look at' any of the prisoners. Whether or not the guard is actually judging each move
of the prisoners matters less than the fact that they are completely and constantly under watch, with
every move the possibility of scrutiny. This idea of a panopticon creates a "persistent self–
monitoring and self–regulation", causing the prisoners to internalize the disciplinary regime that
they are under. The idea behind the gaze and panopticon is that through the both of them, they create

Human Anatomy 5th Period Cataracts
What is Cataracts if you may ask? A cataract is an eye disease in which the natural lens of the eye
gradually degrades the visual quality. The natural lens sits behind the colorful part of the eye known
as the iris in the area known as the pupil, which cannot be seen unless it becomes very cloudy. This
is crucial, because the lens plays a significant role in focusing a light on the retina at the back of the
eye. The retina turns light into a neurologic signal that the brains takes and then interprets it to be
vision. What cataracts do is block the light passing through the lens therefore causing visual
symptoms ... Show more content on Helpwriting.net ...
Secondary cataracts can be formed by if for example an eye was recently worked on for different
eye issues and diseases. Traumatic cataracts occur when a year after an event occurs and the eye is
damaged cataracts develops. It can occur from blunt trauma to the eye or from exposure of the eye
to alkaline chemicals. A congenital cataract is when a child is born with cataracts. Depending on the
genes, the inherited condition may be insignificant enough to the point where it does interfere with
vision. If the child's vision is disturbed the lens of the eye will be replaced with synthetic lens.
Congenital cataracts can also occur from specific illnesses or infections that the mother has during
pregnancy. Disorders such as Rubella and galactosemic increases the chances that your child will
acquire congenital cataracts. The last form of cataracts is radiation cataracts. This form of cataracts
is caused by an over exposure to ultraviolet sunlight and other forms of radiation. Exposure to
sunlight in a prolonged period of time doubles the risk of obtaining radiation cataracts. An
interesting point I found was that cataracts cannot spread from one eye to the other. The best way to
prevent or try to prevent cataracts from occurring is by doing and cutting back on many different
things. Because cataracts Is not completely preventable, you can at least delay its occurrence. You
can try to quit smoking, avoiding over exposure to sunlight, and avoid drinking excess

Diabetic Retinopathy
1. Briefly define the following parts of the eye and their role in vision:
A. Optic Nerve: each of the second pair of cranial nerves, transmitting impulses
to the brain from the retina at the back of the eye.
It is where energy is converted into electrical energy so it can travel to the brain and trigger
responses. The optic nerve is a continuation of rods and cones which make up the retina.
However, at its head, there is a blind spot because there are no photoreceptors in this part of
the optic nerve. This blind spot does not cause problems for people when seeing.
B. Macula: an oval yellowish(means that it absorbs blue and violet light which would
harm the retina thus acting as a protector/ sunblock for the retina.

However, even patients with controlled diabetes can develop diabetic retinopathy.
It is important for diabetic patients to be examined yearly because there are no
symptoms of diabetic retinopathy so early detection and treatment can help reduce the
risk of permanent vision loss. two forms of diabetic retinopathy:
Nonproliferative: this is where exisiting blood vessels in the retina completely deteriorate. These
deteriorated blood vessels can become blocked or develop into aneurysms. Then fats, fluids,
and proteins leak out of the abnormal blood vessels. The fluids then collect in the retina and
cause the macula to swell, this is called edema. Edema impairs the vision responsible for

seeing fine detail and reading.
Proliferative: This is where new blood vessels grow on the surface of the retina which cause
small hemorrhages and bleeding. This causes scar formation which allows the clear gel of the
vitreous to adhere to the retina. This puts pressure on the shape of the vitreous causing it to
change its shape and tear the retina causing retinal detachment. It can treated can be treated
three ways:
Photcoagulation: A focal is used to burn the areas of the retina where the abnormal

Monocular Depth Cues: Walt Disney World
The way we perceive objects depends on different things. One thing that changes the way we view
things is monocular depth cues. Monocular depth cues are cues on depth perception that are
accessible only to one eye at a time. There are actually a couple of different monocular depth cues.
The ones that I will cover will be size constancy, aerial perspective, linear perspective, and texture
gradient. Size constancy refers to the tendency to perceive an object or objects as the same size
regardless of it being near or far. For example, the imagineers at Walt Disney World use this with
their Christmas tree to make it appear bigger. At the bottom of the tree, they place ornaments that are
huge. Since people see the huge ornaments at the bottom of ... Show more content on

The next monocular depth cue there is is aerial perspective. Aerial perspective is a technique that
artist use to make objects appear to be distant. The imagineers at Walt Disney also use this technique
in their park. You can see it in Epcot where the Eiffel Tower is displayed. The imagineers used hazy
paint on the Eiffel Tower to make it appear as if it were further away & taller than it actually is. In
addition, another monocular depth cue that the imagineers use to make objects appear to be distance
is texture gradient. In the New York section of Streets of America, the imagineers used less texture
on the buildings to make them appear to be distant. They only used defined details on the first few
buildings, the rest are less detailed. The next depth cue is linear perspective. Linear perspective is a
type of perspective that is used to create an illusion of depth. The imagineers also used this
perspective technique in the New York section of Streets of America at Disney. If you pay close
attention, you will notice that the street lines on the road are actually angled inward to make it
appear as if there were great

Gravity Roads and Gravity Hills
Have you ever dreamed about going up into space feeling the weightlessness without gravity? While
not everyone can have such an opportunity, there are still places that ignore the rules of gravity.
Gravity hills allow all types of objects to travel uphill. What are they? How do they work? If you
park your car at the bottom of these roads, then place it in neutral, your car will begin to travel
upward. The same process works for water, tennis balls, pop cans or basically anything. Gravity
hills seem like a dream come true, but this is all just smoke and mirrors, an optical illusion. The
discoveries of these hills happened very gradually. There was no specific time or place. Every hill
has their own story of a new mystical place that defies gravity. When a gravity hill was discovered it
would begin with news casts. Then, someone would buy the property making it into a showplace for
people to come and visit. There many places that have been long since discovered, and probably
many more yet to be found. This may all seem too good to be true. Well, it is. There were many
experiments conducted, trying to figure out how these hills work. At first people believed that they
was a magnetic force pulling their car upward, but how does that explain the tennis ball and the
water traveling upward? Scientist finally came upon the discovery of how our own eyes are tricking
us. We see uphills easier then we see a downhill. To prove this scientists set up 3 boards, the one in
the middle is

Glaucom A Case Study
Glaucoma is a group of eye diseases characterized by increased intraocular pressure, resulting in
atrophy of the optic nerve. (Venes, D. 2013) This disease is known to gradually cause the loss of
peripheral vision which can eventually lead to total blindness. Glaucoma is the third most prevalent
cause of visual impairment and blindness in the U.S, although the incidence of blindness is
decreasing due to early detection and treatment. (Venes, D. 2013) Glaucoma comes in two major
categories: closed–angle glaucoma, and open–angle glaucoma. (Holistic Nursing Practice, Vol. 24)
1. Closed–angle glaucoma. Also called acute or chronic angle–closure or narrow–angle glaucoma,
this type of glaucoma is less common. Poor drainage is caused because the angle between the iris
and the cornea is too narrow and is physically blocked ... Show more content on Helpwriting.net ...
Your eye care professional applies a numbing drop to your eye and uses an ultrasonic wave
instrument to measure the thickness of your cornea.
Fig. 4 Tonometer (source: Holistic Nursing Practice vol. 24)
Treatment:
Eye drops for glaucoma. These medications seems to either reduce how much fluid is formed in the
front of the eye or treat it by increasing the outflow of its fluids.
Laser surgery for glaucoma. Laser surgery for glaucoma slightly increases the outflow of the fluid
from the eye in open–angle glaucoma or eliminates fluid blockage in angle–closure glaucoma.
Microsurgery for glaucoma. In a procedure called a trabeculectomy, a new channel is created to help
drain the fluid, which in effect, decreases the intraocular pressure that causes glaucoma.
Prognosis:
At this time, the loss of vision caused by glaucoma is irreversible and cannot be restored. However,
successfully lowering eye pressure can help prevent further visual loss from glaucoma. Most
patients with glaucoma do not necessarily go blind if as long as follow their treatment plan and go
for regular eye

Even though technology makes things easier and faster it still has its drawbacks. One of the many
positive effects of technology is that communication in the criminal justice field goes around much
quicker. At their disposal are technological advancements like faxes, internet, and email. All three
can help get information to other counties or stations a lot faster than if that technology wasn't
available. For example, if there is a man that is wanted and on the run an officer can fax over the
information and a picture to another county. The same officer can also send out a massive email to
other stations and counties to keep the eye out for the suspect. An email or a fax can be done in a
matter of seconds to just a few minutes. If it wasn't available the officers would have to depend on
phone calls or snail mail which just doesn't do the job a fax or email with an attached picture would
do. The internet is also at their disposal and it is completely stocked with information of great
magnitudes.
With any great things there are drawbacks. One of the main drawbacks of fax, email or internet is if
there is no power. If there is a shortage or a blackout these types of technologies are no longer
available for use. They all depend completely on electricity and without it cannot function. There is
also the problem of breaks or glitches. There are times when internet or email runs very slowly
because of glitches. There could also be a problem with the cords

It is contrasted with real world to further reinforce the lack of nature in society. The short length of
the scene, and the fact that the scene is only Deckard's dream, conveys the elusiveness of nature and
shows us that humans still ‘dream' of having the presence of nature back in their world–weary
lives. Another method used by the cinematographers to show the want for nature is through the
presence of artificial animals. While the artificiality of the animals shows the destruction of nature
the way humans still keep them as pets conveys their yearning to bring back nature.
<br>
<br>The decay of human spirit is also shown through the dialogue. In Bladerunner the scarcity of
the dialogue itself potrays the lack of human interaction and consequently the lack of empathy or
emotion. Characters only speak when it is necessary for their own survival and comfort but not for
the sake of emotional involvement. However, the replicant slaves, who supposedly feel no emotion,
interact more sensitively with each other. This irony again has the effect of showing the
dehumanisation suffered by this society. The absence of nature and the way society deals with this is
revealed through the way they refer to nature. For example at Tyrell's office Decker asks Racheal if
the owl is artificial, to which she replies "of course it is." A similar conversation that occurs later

Introduction
While interacting with the world, human visual system is perhaps the first and foremost biological
process system that directly involves in detecting information. As Colin Ware (2013) noted in
Information Visualization, "We acquire more information through vision than through all of the
other senses combined". Hence, it is crucial for information designers to understand influential
factors which affect our visual system in order to optimize information visualization for users. With
visual sensory system acting as a signal detecting system, this paper intends to look at a variety of
perceptual elements of a particular case but mainly focuses on their visibility in terms of contrast
and color. More specifically, the paper will be examining these concepts as if the website is viewing

Many kids and adults have some kind of video game whether it be on the computer, phone, or a
game console. So many people think video games are bad for you, your health, and your mind but
have no hard evidence to prove it. Here is some hard evidence proving them wrong. Studies have
shown that video games, especially shooting or violent video games, improve your eyesight. There
is no hard evidence that links violent video games to causing violent crimes. Some people believe
the reason that teenagers kill and commit crimes are because of violent video games, but that is not
why. It's usually something emotional going on in their life like stress, or something much worse.
People believe that video games are bad for us when they really aren't because the tests have shown
us just that.
