What are the causes of blurry eyes?

The eye is a complex organ composed of various delicate parts, which is the basis of human vision. Therefore, any problem in any part of the eye will affect the health of the eye. Blurred eyes are a typical manifestation of impaired vision and a specific symptom of unhealthy eyes. It requires people’s high attention. Let’s take a look at the causes of blurred eyes.

1. Visual fatigue causes 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.

2. Fatigue and lack of oxygen

Blurred vision is caused by excessive fatigue. If the eyes do not get rest, the vision will become blurred. After a good night’s sleep, the vision will become clear.

3. 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.

4. 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.

5. Glaucoma, cataracts and other eye diseases

Glaucoma is a common and difficult eye disease that develops rapidly, is highly harmful, and can cause blindness at any time. The characteristic is that the intraocular pressure intermittently or continuously rises to a level that exceeds the tolerance of the eyeball, causing damage to various tissues and visual functions of the eyeball, leading to optic nerve atrophy, narrowing of the visual field, decreased vision, and even blindness. Glaucoma is a binocular disease that can affect both eyes at the same time, or start in one eye and lead to blindness in both eyes. The main symptom of cataracts is blurred vision, which may be accompanied by fear of light, objects appearing darker or yellower, and even double vision and distorted objects.
