Which diseases can cause blurred vision

Blurred vision is a condition that most of us may have experienced before. Sometimes you may not fully wake up yet, but after waking up you may see things with blurry eyes. In fact, there are many reasons for blurred vision. In addition to some eye diseases, blurred vision may also be caused by other diseases, such as complications of diabetes or lack of certain vitamins in the body, which can cause changes in our vision. Let’s take a look at the detailed reasons below.

Six reasons why your eyes may be blurry

Don’t ignore blurred vision. Most people ignore the phenomenon of blurred vision because they are too busy at work. When vision loss or eye fatigue and pain occur, people simply think that it is just fatigue. However, doctors warn against this because it could be a precursor to many serious conditions, such as retinal detachment, cataracts or dry eyes, or it could be a blood sugar abnormality caused by diabetes. These conditions are likely to lead to serious consequences and permanent damage to vision.

Causes of blurry eyes

1. High intraocular pressure may cause blurred vision

If you feel as if there is a layer of transparent substance in front of your eyes and your vision is blurred when you look at things, it cannot be ruled out that it is caused by cataracts. You can go to an ophthalmologist to have an intraocular pressure test. In many cases, especially for the elderly, blurred vision is caused by cataracts. High intraocular pressure often leads to blurred vision.

2. Sleeping on your stomach can cause blurry eyes

Many people have had this experience: when they fall asleep on a desk and then wake up and open their eyes, they often feel blurry vision. This is because sleeping at a desk causes high intraocular pressure, which leads to corneal deformation, congestion of the eyeball, and increased intraocular pressure, resulting in short-term blurred vision. For this type of blurred vision, try not to sleep on your stomach and reduce the pressure on your eyes as much as possible, which will also reduce the occurrence of blurred vision symptoms.

3. Eye inflammation can cause blurred vision

If you suffer from eye inflammation such as keratitis, retinitis, stromal keratitis, etc., the inflamed eye will often become blurred and unable to see clearly.

4. Visual fatigue leads to blurred vision

The frequent use of computers, televisions, etc. can cause great harm to the eyes, especially in poor lighting and sitting postures, which can make visual fatigue more likely. This is the reason why most people have blurred vision.

5. Vitamin deficiency

Vitamins play an important role in human growth, metabolism and development. Among them, vitamin A is the raw material of rhodopsin in the eyes and is an important substance for maintaining vision. Lack of vitamin A can cause blurred vision, dry eyes, night blindness, etc. You can eat more foods rich in vitamin A to relieve the symptoms of blurred vision, such as carrots, chicken liver, eel, cabbage, carrots, cauliflower, mango, kiwi, grapes, kiwi fruit, tomatoes, yellow corn, etc.

6. Diabetes

For a certain group of people, there is another explanation for the blurry vision: diabetes. Patients may experience blurred vision, edema, congestion, and even retinal detachment. Retinopathy is the most serious complication of diabetes in the eye. Diabetic patients should control their blood sugar intake, have regular fundus examinations, and control their blood pressure and blood lipids.
