Here are 8 causes of blurred vision accompanied by headaches

Blurred vision occurs when your eye loses the ability to see objects or objects clearly. Although this condition is sometimes underestimated, blurred vision can actually indicate a disease or other more serious health problem. What causes blurred eyes and blurry vision? Then, how to solve it? Check out the full explanation below.

What is the cause behind blurred eyes?

When a person experiences blurred vision, it can be a result of various health conditions. Blurred vision can occur in one eye or both eyes.

Sometimes the symptom of blurred eyes is accompanied by other symptoms, such as a sudden onset of headache or dizziness. For that, consult your doctor for changes in vision and dizziness that occurs to you, especially if they occur suddenly.

Well, here are the various causes of blurred and shaded eyes, ranging from mild to severe:

1. Eye refractive disorders

Eye refraction disorders are the most common cause of vision problems in the world, including blurred eyes. This condition occurs when light entering the eye is unable to focus on the retina. As a result, the object or objects you see will appear blurry and blurry.

There are various types of eye refractive errors, namely:

Farsightedness (hypermetropy): causes blurred vision when looking at near objects, such as when reading a book or using a computer.
Nearsightedness (myopia): causes blurry vision when viewing objects from a distance, such as when watching TV or driving.
Astigmatism: causes double vision when viewing objects from near or far away.
Presbyopia: occurs in people aged 40 years and over who experience blurred near vision, this condition is associated with increasing age.

Blurred eye conditions can get worse if not treated properly, especially if the size of the glasses used does not match the eye condition.

2. Eye infection

Eye infections can be caused by many things. One that is quite common is conjunctivitis, which is when the conjunctiva of the eye is infected by viruses, bacteria, or allergens.

This condition causes the eyes to become red, itchy, watery, and affects vision so that objects that are seen appear blurry and blurry. Conjunctivitis can be caused by seasonal flu, contracting another person who is infected, or exposure to a substance that triggers an allergy.

In addition, eye infections can also occur due to improper use of contact lenses. Usually, infection due to contact lenses is caused by the buildup of bacteria or viruses on the lenses that are not cleaned and cared for properly.

3. Cataracts

Cataracts can also cause blurry vision and lightheadedness. Cataract is a condition when there are spots or fog-like stains on the lens of the eye.

Eyes affected by cataracts cause vision to be blurry and blurry. Sometimes, the object that is seen will appear shaded, or what is also called double vision.

This condition is generally caused by old age. However, certain diseases such as diabetes can also trigger cataracts.

4. Glaucoma

Glaucoma is an eye disease that occurs when there is damage to the optic nerve. There are two forms of glaucoma that are most common, namely open-angle glaucoma and angle-closure glaucoma.

Glaucoma sufferers usually do not feel any symptoms in the early stages of the disease. Symptoms such as blurred eyes can appear suddenly. This disease can also be accompanied by other symptoms, such as dizziness, headache, sore eyes, nausea, and vomiting.

5. Diabetes

Diabetes is a disease that affects insulin's ability to control sugar levels in the body. People with diabetes have high levels of sugar in their blood, so this can have an impact on various health problems, including vision.

According to the American Academy of Ophthalmology, one of the most common eye disorders affecting diabetics is diabetic retinopathy. High blood sugar levels cause damage to the retina (back of the eye). The final stage of diabetic retinopathy, known as macular edema, can cause blurred vision.

Apart from diabetic retinopathy, other eye disorders that cause eye blur in people with diabetes are macular edema, cataracts, and glaucoma. These four eye disorders can affect the quality of vision, resulting in symptoms of blurred eyes.

6. Blood pressure is too high or low

Abnormal blood pressure can also lead to blurry eye conditions. Blood pressure is said to be low if the number falls below 90/60 mmHg, while high blood pressure or hypertension is in the range of 130/80 mmHg.

The causes of high and low blood pressure can vary, from an unhealthy diet, physical activity, bleeding, and consumption of certain drugs. Low blood pressure causes various symptoms ranging from headaches, blurred vision, nausea, weakness, decreased concentration, and even fainting.

7. Migraine

Migraine is a headache that occurs on one side of the head. Migraines have several different symptoms depending on the stage. When the main attack of this one-sided headache peaks, blurred vision may occur. Other symptoms that arise are lack of appetite and increased sensitivity to light, sound, or smells.

Migraine triggers also vary, ranging from foods high in sodium, drinking alcohol and high in caffeine, stress, the effects of medication, to sleep patterns.

8. Neck injury

Neck injury or whiplash it can occur in car accidents, sports that involve physical contact (soccer, karate, boxing, etc.), falls from a bicycle, or falling objects that make the head jerk back.

This condition will cause injury to ligaments, muscles, bones and joints. About 24 hours after the incident occurred, usually there will be some symptoms of headache, especially in the back, blurred vision, and neck stiffness.

9. Condition of nerves and blood vessels

Various nerve and blood vessel conditions can cause blurred vision and headaches. Head injury, stroke, or ruptured blood vessels in the brain, infection of the brain and tissues around the brain, and tumors can also cause symptoms of blurred vision and headaches.

10. Macular degeneration

The macula is the center of the retina at the back of your eye. It's what lets you see details, colors, and objects right in front of you. Degeneration of the macula of the eye causes central vision to become blurred.

11. Retina detachment

Detached retina is a medical emergency that can cause sudden blurry eyes. It can also cause other symptoms, such as blinking and floaters, as well as sudden blindness.

Retinal detachment can result from injury to the retina, as well as a buildup of fluid under the retina.

How to treat and prevent blurry eyes?

If you have complaints of blurred eyes, immediately consult an ophthalmologist to get a diagnosis of the cause of your condition.

By knowing the exact cause of your visual disturbance, the treatment given can certainly treat the disease or disorder you are experiencing with the right target.

For example, if your blurry eyes are caused by a refractive disorder, your doctor will perform an examination of the sharpness of your eye. After that, you will be given a prescription for glasses that suit your eye condition.

If your blurry eyes are triggered by a chronic disease such as diabetes, you should of course take the medicines your doctor prescribes to control the sugar levels in your body. This will control the symptoms of diabetes, including blurred vision.

Then, is there a way to prevent blurry eyes? The only way you can take it is to keep your eyes healthy. Some tips that you can do to maintain the quality of your vision are:
