  Fact-checking   Autentic   DMCA   Report

Blurred vision is a relatively common symptom, especially in people who have a vision problem, such as myopia or hyperopia, for example. In these cases, it may be necessary to correct the graduation of the lenses, which is why it is important to schedule an appointment with the ophthalmologist.

However, when blurred vision appears suddenly, apart from being the first sign of a vision problem, it could be a symptom of more serious problems, such as conjunctivitis, cataracts and even diabetes.

Know what are the most common problems and their symptoms.

1. Myopia or hyperopia

Myopia and hyperopia are two of the most common eye problems. Myopia occurs when the person cannot see correctly from a distance and hyperopia when it is difficult to see close up. Associated with blurry vision, other symptoms such as constant headache, easy tiredness and the need to close eyes frequently also appear.

What to do: you should consult an ophthalmologist to carry out a vision exam and determine what the problem is, with the purpose of initiating the most appropriate treatment, which usually includes the use of graduated lenses, contact lenses (pupillents) or surgery.

2. Presbytery

Presbicia is another very frequent problem, especially in people older than 40 years of age; this one is characterized by difficulty to focus objects or texts that are around. For the general reason, people with this problem need to support the magazines and the books by the eyes to achieve a better focus on the letters.

What to do: Presbicia can be confirmed by an ophthalmologist and is generally corrected by using lenses to read with graduation.

3. Conjunctivitis

Another situation that can lead to the emergence of blurred vision is conjunctivitis. This is a relatively common eye condition caused by the flu virus, bacteria or fungi, which can easily be spread from one person to another. Other symptoms of conjunctivitis include reddening of the eyes, comezón, sensation of sand in the eye or presence of lagñas. Learn more about the main types of conjunctivitis.

What to do: It is necessary to identify if the infection is being caused by bacteria, you may need to use eye drops or antibiotic ointment, such as tobramycin or ciprofloxacin. Therefore, you should consult an ophthalmologist to find out what the best treatment is.

4. Diabetes

Blurred vision can be a complication of diabetes called retinopathy, which occurs due to the degradation of the retina, the vessels and the nerves. This generally occurs in people who do not have the proper treatment of the illness, because the sugar levels are constantly high in blood. In the event that diabetes remains uncontrolled, there may even be a risk of blindness. Know why diabetes can cause blindness.

What to do: In case you have diagnosed diabetes, you must have an adequate diet, avoiding processed and sugary foods, as well as correctly taking the medicines indicated by the doctor. However, in the event that diabetes has not been diagnosed, but there are other symptoms such as the frequent desire to urinate excessively, a general physician or endocrinologist should be consulted.

5. High pressure

If less frequent, the high pressure can also generate blurry vision. This is because, as in cases of stroke or infarction, high blood pressure can also cause obstruction of eye vessels, affecting vision. In general, this problem does not cause any kind of pain; However, it is more common for the person to rise with blurred vision, especially in a single eye.

What to do: In case there is any suspicion that the blurred vision is being caused by high blood pressure, you should go to the hospital or consult a general practitioner. Many times, this problem can be treated with the proper use of aspirin or another medication that helps the blood to become more fluid.

6. Cataract or Glaucoma

Cataracts and glaucoma are other age-related vision problems that appear progressively throughout life, especially in the 50s. The cataract could be easier to identify, it could cause the appearance of a white layer in the eye. On the other hand, general glaucoma is accompanied by other symptoms, such as intense pain in the eye and loss of visual field, for example. Know the most common symptoms of glaucoma.

What to do: If there is a suspicion of one of these disorders of vision, you should consult an ophthalmologist to confirm the diagnosis and start the most suitable treatment, which may include the use of specific eye drops or the performance of surgery.
