The eyes is one of the most valuable organ of the human
body. It will not last if it is abused.
Some common cause of eye problems are
due to aging, birth defects,over exposure to too much light , heredity and secondary illness of other diseases.
Exercising the eyes can improve the sight. One simple exercise is to look at the object you want to see and circle the outer boundaries with your eyes before centering on it. When doing close up work always stop and look way out in the distance ever .once in a while.
Try looking at the ground with the corner of your left eye and at the sky with the corner of the right eye holding your head in one central position.
Here are some of the more common degenerating eyes diseases below but there are many many more.
Myopia
This condition, commonly known as nearsightedness, occurs
when light rays entering the eye focus in front of the retina, not directly on
it. People with myopia are usually able to see close objects well, but objects
in the distance—such as highway signs or writing on a chalkboard—appear
blurred. People with this condition may squint to see distant objects and
experience eyestrain or, sometimes, headaches. Eyeglasses or contact lenses can
correct myopia. Surgery is another alternative.
Hyperopia
This common vision problem, also known as farsightedness,
occurs when light rays entering the eye focus behind the retina, not directly
on it. People with hyperopia are usually able to see distant objects well, but
close objects appear blurry. Hyperopia may cause eyestrain or headaches,
especially with reading. Eyeglasses or contact lenses can correct hyperopia.
For people who do not want to wear glasses or contact lenses, laser vision
correction is sometimes possible.
Glaucoma
Disease in which the pressure of the fluid inside the eye is
too high, resulting in a loss of peripheral vision. If the condition is not
diagnosed and treated, the increased pressure can damage the optic nerve and
eventually lead to blindness. Vision lost as a result of such damage cannot be
restored. A person who has glaucoma may not realize it at first, because the
disease often progresses with no symptoms or warning signs. Early detection
through regular eye examination and prompt treatment is essential to prevent
vision loss. Daily medication (usually eye drops), surgery, or a combination of
both enables most people to control their intraocular pressure and retain their
vision.
Cataract
A condition in which the lens of the eye, which is normally
clear, becomes cloudy or opaque. Cataracts generally form slowly and without
pain. They can affect one or both eyes. Over time, a cataract may interfere
with vision, causing images to appear blurred or fuzzy and colors to seem
faded. Most cataracts are related to aging. In fact, cataracts affect more than
50 percent of all adults by age 80 and are the primary cause of vision loss in
people 55 and older.
Those with high blood sugar, those who take steroids, people with heavy metal poisoning,
people using hair dyes, smokers. and lack of vitamins. People with early
cataract may benefit from new eyeglasses, bright lighting, anti-glare
sunglasses, or magnifying lenses. If, despite such devices, cataract interferes
with daily activities, surgery is the only effective treatment. Cataract
surgery, which is common, involves removal of the cloudy lens and replacement
with an artificial lens.
Natural remedy is to eat whole grains, nuts, fruits, and get
enough vitamin A,B.C
Relaxing during the day is good for the rye..
Diabetic retinopathy
Eye condition that results from the damaging effect of
diabetes on the circulatory system of the retina. The longer someone has had
diabetes, the greater the person's likelihood of developing diabetic
retinopathy. Changes in the tiny blood vessels of the retina can lead to vision
loss. People with diabetes should have routine eye examinations so that
diabetes-related problems can be diagnosed and treated as soon as possible.
Maintaining strict control of blood sugar levels helps to prevent diabetic
retinopathy. Surgical and laser treatments can help many people affected with
this condition
Photophobia
This is the inability of the eyes to
tolerate light. It is where looking at
normally bright objects hurts the eye. This can occur occasionally or gradually increases
usual. The chief cause of this is a lack of vitamin A in the diet. It is
usually experience by
individuals who
smoke marijuana. If the problem is vitamin A related add 25.0001U daily for a
few days as more can be dangerous. Increase the intake of beta carotene in diet.
Drink 3 glasses carrot juice daily .Use moderately morenga
