You can’t see objects well, you can’t distinguish people (especially their faces), you have trouble reading, or you feel like the letters on your computer or the pages of a book are moving.

Maybe it’s time to consult a doctor. In this article we will find together some facts about the causes of blurred vision and how to avoid it.

Causes Of Blurred Vision

Nearsightedness (Myopia)

With nearsightedness (Myopia) the eye does not refract the light properly to get a clear image. Nearby objects appear clear, but distant objects blur. Myopia is a common condition that affects about 25% of the people.

This is a disorder of focusing the image in the eyes and not an eye disease. Myopia can range from mild, where treatment may not be required, to severe, when a person’s vision is significantly impaired.



Cataract is more common in people over the age of 60 and sometimes there are no symptoms to detect it. In other cases, cataracts cause corneal opacity, progressive blurring of the vision, sensitivity to light, a halo of light, double vision.


One of the many symptoms of an imbalance in blood sugar levels can be blurred vision. You need to pay special attention if you suffer from diabetes. Lack of care will lead to much more serious vision problems, including blindness.

Graves’ Disease

Weight loss and increased appetite, palpitations, high blood pressure, tremors and blurred vision are the most obvious symptoms of this disease, which affects the thyroid gland.

This neurodegenerative disorder is often accompanied by a number of vision problems, including blurred vision. It can cause problems with bladder control, changes in sensations, etc.


When blood sugar levels drop suddenly, it can lead not only to blurred vision, but also to other types of disorders – confusion, double vision, seizures, loss of concentration, anxiety, palpitations and tremors.


If you experience severe headaches due to a muscle or neuronal problem, blurred vision is the most common symptom. Other signs include nausea, sensitivity to light, eye pain and vomiting. Migraines can have the same symptoms.

High Blood Pressure and Glaucoma

With both cases – hypertension or elevated intraocular pressure (glaucoma), you may have vision disorder. In addition, both diseases generate additional problems such as loss of consciousness, complete or partial loss of vision, tachycardia and others.

How To Avoid Blurred Vision

If you have often had any of the above symptoms, it is important to contact your GP immediately. If you have experienced only one symptom from time to time, then pay attention to the following tips:

Reduce Stress

This will help lower your blood pressure and nervousness. You will be calmer and you will see better. Hypertension is one of the biggest enemies of the eyes because it weakens them.

If you experience eye strain, it is good to rest more. Reduce anger and anxiety so that they do not cause you additional problems.

Relax Your Eyes

If you have been working in front of a computer for a long time, your eyes may become tired and this may cause blurred vision. Stay seated and close your eyes for 1 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.

Then do the same, but moving your finger to the right and then to the left, as if following the direction of the pendulum. Move only your eyes, keep your head still.

Focus And Defocus

Choose an object and focus on it. Then defocus your gaze and see what is around the object. One of the reasons our vision is blurred is because we are not used to focusing on a specific element due to the hundreds of other things that surround us every hour.

Be Careful With Your Daily Diet

You probably already know that water is the best ally to keep your body hydrated. This includes your eyes. It can also help remove toxins that have accumulated in the body and that could damage the liver – an organ directly connected to the eyes. If your vision is blurred or cloudy, try to follow a fat-free diet and avoid fried foods.

Drink boldo tea every day and follow a cleansing diet with steamed or partially cooked vegetables (especially broccoli, spinach and white beets) with whole grain rice. Give up fats, meat and dairy products.

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

Maintain a Healthy Lifestyle

Increase the size of the letters on the computer screen so that you do not have to approach it, do not read if you do not have enough light. Natural light is much more useful than artificial light. Stay at a distance of at least 1 meter from the TV screen and wear sunglasses when going outside.

It is also good to spend some time in nature, for example in the countryside or in the mountains. This way you will take very good care of your eyes – they need to rest from constantly seeing so many things, especially all colors, neon and bright lights.
