Thousands of people suffer daily from blurred or diffuse vision, a disorder that has many causes and one you should not ignore. Above all if this problem is accompanied by headaches, dizziness, tiredness and nausea, it is very important that you find out why and how to prevent it.

In this article you will discover some facts about blurred vision, why it happens and how to treat it.

Causes of blurred vision

This list will help you to determine what is the cause of your blurred vision and the most common symptoms.

Astigmatism or myopia

The first cause is a disorder that shortens your near vision. And the second one limits your far vision. In addition to blurred vision it distorts the entire visual field.


These are more common in people over 60 years old and sometimes they have no symptoms. In other cases, they cause corneal opacity, blurred vision, light sensitivity, halo of light, double vision and progressive blurring of the vision.



One of the many symptoms of an imbalance in the blood sugar levels can be blurry vision. You must pay close attention if you suffer from this illness because a lack of care will result in much more serious vision problems including blindness.

Grave’s disease

Weight loss and increased appetite, rapid heartbeat, high blood pressure, tremors and blurry vision are the most notorious symptoms of this ailment that affects the thyroid gland.

Multiple sclerosis

This neurodegenerative disorder is often accompanied by multiple vision problems, including blurry vision. It can also cause problems with bladder control, changes in sensation, etc.


When the blood sugar levels drop suddenly this can cause not only blurred vision, but also other types of visual disturbances, confusion, double vision, convulsions, loss of concentration, anxiety, palpitations and shakiness.



When the head experiences too much pain due to a muscular or neuronal problem, blurry vision is the most common symptom. Other signs are nausea, light sensitivity, pain in the eyes and vomiting. Migraines can have the same symptoms.

High blood pressure and glaucoma

Both if we have hypertension or eye pressure (glaucoma), we can have problems seeing well. Further, both ailments generate additional problems such as fainting, total or partial loss of vision, tachycardia, etc.

How to avoid blurry vision

If you have often experienced any of the foregoing symptoms, it is very important that you see your doctor immediately. If you have only experienced these sporadically, then pay attention to the following advice:

Reduce stress

This will help you to lower your blood pressure and nervousness. Therefore, you will be more serene and you will see better. Hypertension is one of the worst enemies of your eyes because it wears them down. If you have ocular tension it is also good that you de-stress. Work on lowering your anger and anxiety so that these do not cause you addition problems.


Relax your eyes

If you have been working a long time in front of a computer screen or laptop, your eyes may become tired and this will cause blurry vision. Remain seated and close your eyes for a minute. Another option is to stand up, place your index finger in front of your face and zoom in and out slowly, while keeping your eyes fixed on your finger. Afterward do the same but by moving your finger to the right and then the left, as if it were a pendulum. You should only move your eyes to follow it, not the head.

Focus and un-focus

Select and object and stare at it, focus on it. Afterward, try to un-focus on the object and instead see what is around it. One of the reasons why our vision becomes blurred is because we are not accustomed to focusing on one item in particular, due to the hundreds of stimulants that we receive daily.

Watch your diet

Surely you already know that water is your best ally to keep your body hydrated, including your eyes. Also, it can help eliminate the toxins which have accumulated in the body and which could harm the liver, the organ directly related to the eyes. If your vision is blurry or cloudy, try to follow a fat free diet and avoid fried foods. Drink Boldo tea every day and eat a cleansing diet of steamed or partly cooked vegetables (above all, broccoli, spinach and chard) with whole grain rice. Do not eat fats, meats or milk products.

At the same time, increase your intake of vitamins A and C. You will find these in citrus fruits, carrots, papaya and broccoli.

Maintain healthy habits

Increase the size of the letters on your computer screen so that you do not have to move the screen closer to your eyes, do not read when there is insufficient light (natural light is better than artificial light), keep a distance of at least one meter (three feet) from your television screen and wear sunglasses when on break at work or when you get home.

It is also good to spend some time in rural or natural environments, such as in the countryside or at the beach. In this way, you can work the entire field of your eyes. Just like a panoramic photograph, the eyes need a break from seeing so many things all together, especially all the colors, neon lights and bright lights.
