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
. This condition causes the misshapening 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
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
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.
