“THE IMPLICATION OF POOR EYESIGHT TO THE
STUDENTS OF VMHS”
I. INTRODUCTION
A.
Overview
of the Study
Eyesight also known as visual perception is the ability to
interpret information and surroundings from the effects of visible light
reaching the eye. Most of us are born with perfect natural vision. It may sound
hard to believe but everything we do impacts our vision. Even the
smallest things, like reading a book before we fall asleep, can influence our
eye health. That is why when talking about the most common causes and
implications of having poor eyesight, we need to check it out within ourselves
first. Because unfortunately, age and lifestyle habits slowly damage our eyes
until one day we find ourselves visually impaired.
B.
Statement
of the Problem
This research entitled ‘‘The Implication of Poor Eyesight to the
Students of V.M.H.S ’’ seeks to answer the following questions:
1.
What are the causes of poor eyesight ?
2.
What is the impact of having poor eyesight
to the students of VMHS?
3.
What are the ways to prevent poor eyesight ?
4.
What
remedies can be done for having poor eyesight?
C.
Significance
of the Study
This study is significant to the students of VMHS to have a
better understanding of what eye health is and what they can do to maintain
their good sight, what to do when suffering from poor eyesight, and what ways
can be done to prevent having eyesight problems.
This study is also important to the researcher as an addition
to his body of knowledge aside from the lessons that he will gain from
conducting the study.
Furthermore, it will also be very helpful to future
researchers as a basis for conducting their studies and will also be a good
source of reference to other people seeking sources regarding eye checkup.
D.
Scope
and Limitation
This study will only focus regarding research on eyesight
problems, its causes, preventions and remedies. Presentations in this research
shall only be based on textbooks, online media and other related materials.
It will be limited from conducting actual experimentation
like distributing questionnaires and interviews.

II. REVIEW OF RELATED LITERATURE
Vision Problems
There are many types of eye problems and visual disturbances.
These include blurred vision, halos, blind spots, floaters, and other symptoms.
Blurred vision is the loss of sharpness of vision and the inability to see
small details. Blind spots (scotomas) are dark "holes" in the visual
field in which nothing can be seen.
Considerations
Changes in vision,
blurriness, blind spots, halos around lights, or dimness of vision should
always be evaluated by a medical professional. Such changes may represent an
eye disease, aging, eye injury, or a condition like diabetes that affects many
organs in your body.
Whatever the cause, vision
changes should never be ignored. They can get worse and significantly impact
the quality of your life. Professional help is always necessary. As you
determine which professional to see, the following descriptions may help:
·
Opticians
dispense glasses and do not diagnose eye problems.
·
Optometrists
perform eye exams and may diagnose eye problems. They prescribe glasses and
contact lenses. In some states, they treat diseases that affect the eyes.
·
Ophthalmologists
are physicians who diagnose and treat diseases that affect the eyes. These
doctors may also provide routine vision care services, such as prescribing
glasses and contact lenses.
·
Sometimes
an eye problem is part of a general health problem. In these situations, your
primary care provider should also be involved.
Causes
Vision changes and problems can be caused by many different
conditions:
·
Presbyopia
-- difficulty focusing on objects that are close. Often becomes noticeable in
your early to mid 40s.
·
Cataracts
-- cloudiness over the eye's lens, causing poor nighttime vision, halos around
lights, and sensitivity to glare. Daytime vision is eventually affected. Common
in the elderly.
·
Glaucoma
-- increased pressure in the eye, causing poor night vision, blind spots, and
loss of vision to either side. A major cause of blindness. Glaucoma can happen
gradually or suddenly -- if sudden, it's a medical emergency.
·
Diabetic
retinopathy -- this complication of diabetes can lead to bleeding
into the retina. Another common cause of blindness.
·
Macular
degeneration -- loss of central vision, blurred vision (especially
while reading), distorted vision (like seeing wavy lines), and colors appearing
faded. The most common cause of blindness in people over age 60.
·
Eye
infection, inflammation, or injury.
·
Floaters
-- tiny particles drifting across the eye. Although often brief and harmless,
they may be a sign of retinal detachment.
·
Retinal
detachment -- symptoms include floaters, flashes of light across
your visual field, or a sensation of a shade or curtain hanging on one side of
your visual field.
·
Optic
neuritis -- inflammation of the optic nerve from infection or multiple
sclerosis. You may have pain when you move your eye or touch it
through the eyelid.
·
Brain tumor.
·
Bleeding
into the eye.
·
Temporal
arteritis -- inflammation of an artery in the brain that supplies
blood to the optic nerve.
·
Migraine
headaches -- spots of light, halos, or zigzag patterns are common
symptoms prior to the start of the headache. An ophthalmic migraine is when you
have only visual symptoms without a headache.
Other potential causes of vision
problems include fatigue, overexposure to the outdoors (temporary and
reversible blurring of vision), and many medications.
Medications that can affect
vision include antihistamines, anticholinergics, digitalis derivatives
(temporary), some high blood pressure pills (guanethidine, reserpine, and
thiazide diuretics), indomethacin, phenothiazines (like Compazine for nausea,
Thorazine and Stelazine for schizophrenia), medications for malaria, ethambutol
(for tuberculosis), and many others.
Home Care
Safety measures may be
necessary if you have any vision problems. For example, if you have trouble
seeing at night, you should not drive after dusk. It may be helpful to increase
the amount of light in a room or arrange a home to remove hazards. A specialist
at a low-vision clinic may be able to help.
When to Contact a Medical
Professional
If:
·
You
experience partial or complete blindness
in one or both eyes, even if it is only temporary.
·
You
experience double vision, even if it is temporary.
·
You
have a sensation of a shade being pulled over your eyes or a curtain being
drawn from the side.
·
Blind
spots, halos around lights, or areas of distorted vision appear suddenly.
·
You
have eye pain, especially if also red. A red, painful eye is a medical
emergency.
Call your doctor
if you have:
·
Trouble
seeing objects to either side
·
Difficulty
seeing at night or when reading

Vision
changes that seem related to medication (Do NOT stop or change a medication
without talking to your doctor.)
What to Expect at Your Office
Visit
Your provider will check
vision, eye movements, pupils, the back of your eye (called the retina), and
eye pressure when needed. An overall medical evaluation will be done if
necessary.
Your provider will ask
questions about your vision problems, such as:
·
When
did this begin? Did it occur suddenly or gradually?
·
How
often does it occur? How long does it last?
·
When
does it occur? Evening? Morning?
·
Is
the problem in one eye or both eyes?
·
Is
your vision blurred, or is there double vision?
·
Do
you have blind spots?
·
Are
there areas that look black and missing?
·
Is
side (peripheral) vision missing?
·
Are
halos (circles of light) seen around shiny objects or lights?
·
Do
you see flashing lights or zigzag lines?
·
Do
you have sensitivity
to light?
·
Do
stationary objects seem to be moving?
·
Are
colors missing? Is it difficult to differentiate colors?
·
Is
there pain?
·
Are
your eyes crossed? Does one or both of your eyes "drift"?
·
Have
you had an injury, infection, allergy symptoms, added stress or anxiety,
feelings of depression, fatigue, or headache in the last few weeks to months?
Have you been exposed to pollens, wind, sunlight, or chemicals in this time
frame? Have you used any new soaps, lotions, or cosmetics?
·
Is
your vision better after you rest?
·
Is
it better with corrective lenses?
·
Are
there other symptoms present like redness, swelling, headache, pain, itching,
discharge/drainage, a sense that something is in the eye, increased or
decreased tearing, etc.?
·
What
medications do you take?
·
Do
you have diabetes, or is there a family history of diabetes?
The following tests may be performed:
Treatments depend on the
cause. Surgery will be recommended for some conditions (such as cataracts).
Diabetics must control their blood-sugar
level.
Prevention
Regular eye checkups from an
ophthalmologist or optometrist are important. They should be done once a year if
you are over age 65. Your doctor will recommend earlier and more frequent exams
if you have diabetes or if you are already showing early signs of eye problems
from diabetes, high blood pressure, or other causes.
The pressure in your eyes
will be measured at some visits to test for glaucoma. Periodically, your eyes
will be dilated to examine the retina for any signs of problems from aging,
high blood pressure, or diabetes.
These important steps can
prevent eye and vision problems:
·
Wear
sunglasses to protect your eyes.
·
Don't
smoke.
·
Limit
how much alcohol you drink.
·
Keep
your blood pressure and cholesterol under control.
·
Keep
your blood sugars under control if you have diabetes.
·
Eat
foods rich in antioxidants, like green leafy vegetables.
III.
CONCLUSION
When
it comes to eye health, the principle is: what is bad for your body is
ultimately bad for your eyes. That is why general health is one of the first
things to look at. Are you healthy? Do you suffer from chronic illnesses
and take medications on a regular basis? How often do you get ill?
Poor
general health is one of the top factors contributing to poor eyesight and the
development of various eye diseases.
Some
lifestyle habits can also greatly impact your vision. Lack of
physical activity, unbalanced diet, smoking or alcohol consumption are among
the most common causes of eyesight problems.
IV.
RECOMMENDATION
After
a careful study, the researcher firmly recommends maintaining a healthy
lifestyle to prevent future eye illnesses.
Minimizing
computer usage, watching televisions can also do as they emit too much rays
that are harmful to the eyes. But most importantly, the researcher recommends
that we should follow what medical practitioners are telling us like having a
good rest at times, enough sleep, healthy diet and exercise.
