Most people adduce being able to see clearly as a facet that makes you different from others. It’s very hard for most people to see things clearly. They have to squeeze the cells of the eyes, so to speak before they can be able to tell what is exactly in front of them or distinguish one color from the other. If you are in this category of people, then you’ve got what we call “blurry vision”.
But what exactly is blurry vision? Blurry vision is the loss of sharpness of the eyes, making objects appear out of focus as a result of shortsightedness, far-sightedness, or astigmatism. This condition can affect both or one of the eyes.
As important as our eyes are, they can be infected if care isn’t taken. If you feel itchiness in your eyes, or the tendency to scratch the eyes before you can see an object clearly, this is not the time to adduce the situation to a minor problem; it could be that you are suffering from blurry vision. People who have blurred vision have problems identifying traffic signs, navigating the world, and focusing the eyes on the most important objects, especially in school at the workplace.
But what exactly cause blurred visions?
Reasons Your Vision is Blurry
There are several reasons why people develop a blurry vision, as earlier mentioned.
Cataract is one of the most common reasons for blurry vision in older people. When the lens in the front of the eyes becomes blurry and renders the retina incapable of focusing light in the cells, then the person is suffering from cataract. It is usually slow to develop— because it’s associated with aging. Early cataract can be treated with anti-glare sunglasses or magnifying lenses. But when the condition has become worse, the only treatment for it is a surgery which involves replacing the cloudy lens with an artificial lens.
- You have Diabetic Retinopathy
If you are a type 1 or type 2 diabetic, or you have a long history of uncontrolled diabetes, you definitely will develop diabetic retinopathy. Diabetic retinopathy occurs as a result of the damage incurred on the blood vessels of the retina in diabetic patients. Patients with diabetic retinopathy may not find it difficult at the onset, but will gradually lose their sight. According to research, untreated diabetic retinopathy is one of the major causes of blurred vision in the United States. If you have diabetic retinopathy, you ought to see your doctor for proper injections or laser
- Age-related Macular Degeneration
Another leading cause of blurred vision is the development of age-related macular degeneration. This is when the center of the field of vision is totally lost. When you are above 60, you have a higher risk of damaging the macula, an important area closer to the center of the retina which helps you see objects clearly in front of you. While there is no proven treatment for early age-related macular degeneration, high doses of prescribed vitamins and minerals can fight against AMD in its intermediate and late stages. However, the most common and effective treatment for AMD is anti-VEGF therapy, an acronym for ‘vascular endothelial growth factor therapy’ tailored to fight the infections present.
Another chief reason why you are having a blurred vision is as a result of high blood pressure which leads to stroke. High blood pressure could cause a mini-stroke, thus leading to retinal vein occlusion. The method used in treating retinal vein occlusion is the same used in treating patients with age-related macular degeneration.
When you are unable to see objects clearly from a distance, you are suffering from astigmatism. This type of refractive error is caused by an irregularly shaped cornea. Astigmatism makes it difficult for light rays to come to a single focal point on the retina to produce clearer vision. Astigmatism can be corrected with refractive surgery, contact lenses, or eyeglasses.
- Optic Neuritis
One of the onsets of optic neuritis is blurry Multiple sclerosis causes inflammation in the nerves that connect the eyes to the brain, known as the optic nerves. When this happens, it causes a nerve infection or disease called optic neuritis. Optic neuritis can make you lose sight quickly, unable to distinguish one color from the other and make you feel pains when you move the eyes.
While the infection gets better on its own, steroid medication and plasma exchange therapy or blood transfusion could help treat the problem faster.
Pink eyes or conjunctivitis is caused by adenoviruses, viruses which are also responsible for the development of a common Conjunctivitis could also render your vision blurred. In most cases, conjunctivitis goes on its own without treatment. However, if the problem seems so severe, then you have to see a doctor for the best antibiotics to use.
