It can happen sometimes that a person has blurred vision, and it
could be unpleasant. Blurred vision may also be a symptom of another
disease or condition, and this is something worth minding. Why does
blurred vision occur and what are the possible causes? Primarily,
there is the weakening of the eye muscles. This condition causes the
misshaping of the lens of the eyes. When the lenses lose their
elasticity, blurred vision may occur as well. The lenses having to
lose their elasticity is quite inevitable with aging. As much as
this is anticipated, it may be slowed down by antioxidants.
Then
there is macular degeneration, another cause of vision blurring.
Macular degeneration is instigated by the loss of light of the
neurons behind the eyes. With macular degeneration, the neurons
themselves may have been damaged. Thus, it may not be corrected with
the use of glasses alone. Some patients are able to find relief from
this disorder, though. It is when the doctor corrects micronutrients
in the eyes such as zinc, magnesium and selenium. Cataracts are
among the causes of blurred vision as well. Those having cataracts
could find it difficult to drive at night. Headlights of vehicles
can blind and even dazzle them.
Another eye disorder than can cause blurred vision is dry eyes.
When the eyes don't produce enough tears, or when the tear ducts
produce poor quality tears, this can happen. It can be an
uncomfortable sensation when the eyes become dry. Eye itching and
burning, and even loss of vision can happen with this condition. To
remedy dry eyes, the doctor might recommend artificial tears,
special eye drops or eye lubricants. A humidifier in the area can
help to regulate the tear ducts and alleviate eye drying. In serious
cases, surgery could be required for treatment. Blurring can also
happen with myopia.
One may ask what myopia is. It is actually a medical term for
near or shortsightedness. Myopia takes place when there is too much
curving of the cornea. The eye itself could be too long, and this
causes some irregularities. With myopia, objects up close are seen
clearly and those at a distance are blurry. Why does this happen,
one might ask. It's because objects at a distance are too focused on
the eye's retina. Nearsightedness or myopia is quite common,
affecting nearly 25% of the adult American population. The opposite
of nearsightedness is farsightedness or hyperopia, another mild
disorder.
With hyperopia, objects from afar appear clearer, while those up
close are hazy. Hyperopia occurs when the eye is too short, and
images are focused behind the retina. To sum it up, blurred vision
is not to be taken lightly. When it occurs and persists, medical
attention has to be sought. The underlying cause can range from
minor eye disorders such as myopia or hyperopia. Minor as they are,
they can be corrected with glasses. Lenses or laser eye surgery can
also be resorted to for treatment. But then again, there can be
serious causes for blurred vision. Either way, when it one
experiences it, the eyes have to be checked at the soonest possible
time.
