Can dehydration cause blurred vision?




In this article, we want to inform you about the diseases and problems that can cause blurred vision.

So, in order to be aware of the causes of blurred vision, which dehydration is also one of its reasons, stay tuned.

There are several reasons for blurred vision.

To find out the reasons, we recommend that you read on.


Causes of blurred vision

  • MS disease

MS affects the central nervous system and the nervous tissues in the brain and spinal cord, which are located inside the skull and spine. The greatest effect that MS can have on the optic nerves is that it can cause inflammation of the nerves and lead to blurred vision, but all parts of the brain and nerves can be involved. The greatest effect of this disease in a young person will be the involvement of the optic nerve of the eye, which will lead to a decrease in strength and unity of vision.

A person with MS will lose their eyesight in a matter of weeks. In fact, a person's vision will decrease dramatically in a matter of weeks.

Visual impairment caused by neurological diseases is such that a person loses his or her visual acuity, and as a result of this difference, part of the field of vision disappears and one feels a clear difference in his or her vision compared to previous times.

A person with MS develops inflammation of the optic nerve in the eye, in fact the blurring of vision that develops in the eye is such that the sufferer feels that he or she is looking at objects around him or her through opaque glass; This mode lasts for 24 hours.


  • Inflammations and tumors of the eye

Another cause of eye disease and eye nerve involvement is eye tumors.

Inflammation of the eye can be caused by eye tumors.

Tumors of the eye, as well as inflammation inside the eyeball, can both cause loss of visual acuity, and blurred vision.


  • Blurred vision due to lens opacity and cataracts

Cataract means the opacity of the natural lens of the eye that is located behind the iris and pupil. The lens of the eye is composed of 65% and 35% protein.

These proteins are positioned so that their fibers do not interfere with the natural clarity of the lens of the eye. In fact, these fibers are arranged in such a way that light is allowed to pass through them As you age, some of these proteins disrupt their structure and begin to create cloudy areas inside the natural lens, causing light to pass out of the normal state and creating blurred vision.

This condition that causes the lens to become cloudy is called cataract.

A person with cataracts who is sensitive to light will feel foggy and fading of the colors, and the number of contact lenses and glasses will change constantly, and night vision will be blurred.


  • Blurred vision due to refractive errors of the eye

If the patient narrows his eyes and the blurred spot becomes clear, he may have a problem called refractive problems. These problems are well solved with glasses, simple surgeries, and contact lenses.

Doctors have done many studies to identify the factors that cause refractive errors, such as the effect of reading and writing at close range.

Many studies have been done, but it has not been proven with certainty that there is a connection between them and myopia, and it is inferred that too much study does not have a significant effect on the development of myopia, but perhaps those who read more will be more prone to refractive errors.

They also failed to find a definite link between working with a computer and developing myopia, and the inference of many medical professionals is that the use of these devices alone cannot cause a person to wear glasses.

Other factors that can lead to blurred vision include:


  • ocular chalazion

It is a chronic inflammation that develops in one of the small glands that produce fat in the upper and lower eyelids.


  • Another cause is large pterygium in the eye

Large pterygium can cause blurred vision.

Pterygium is one of the eye diseases that if it is large, it is accompanied by redness of the eyes and eye irritation and inflammation of the eyes. In these cases, artificial tear drops are helpful that can relieve the symptoms. severe inflammation with pterygium sometimes requires the use of a short course of corticosteroid drops and ocular anti-inflammatory drops. Large pterygium can exacerbate blurred vision by causing astigmatism.


Other causes include:

  • blows
  • Inflammation
  • Nutrition and
  • Or pressure

Also, people who suddenly have blurred vision The causes of this disorder are different from people who gradually have blurred vision.

One of the important points to consider is that diabetes has a huge impact on our eyes. Diabetes can cause cataracts at a younger age as well as effects on blood circulation in the arteries of the eye and can cause changes in the membranes behind the eye or Rhine and gradually reduce vision and blindness.


Is diplopia different from blurred vision?

diplopia and blurred vision are different.

There are many people who have diplopia but speak of diplopia as blurred vision. How is a person with diplopia identified?

If the patient closes one eye completely and can see with the other eye, he can notice this problem.

If he sees with both eyes, but when he closes one of his eyes, he sees correctly with his open eye, it becomes clear that he has diplopia and his two eyes do not actually have coordination in sight.

It is in these cases that a person should see a neurologist as soon as possible with a diplopia complaint.


Can dehydration cause blurred vision?

We are familiar with a number of causes that can be associated with blurred vision. But We want to answer the following question: What is the effect of dehydration on the eyes and vision?

Dehydration can have many negative effects on various organs of our body. Headache, dizziness, lightheadedness, muscle cramps, tiredness, drowsiness and even increased risk of kidney stones.

But it is interesting to know that when your body is dehydrated, it affects the tear ducts of the eye, causing dry eyes and vision problems, and endangering eye health.


Effects of dehydration on the eyes are as follows :

Dry eyes:

Dry eye is when not enough tears are brought to the surface of the eye through the tear ducts.

The balance between the components of the tear is disturbed and this causes the tear to be insufficient and not able to play a sufficient quality in protecting and moisturizing the surface of the eye.

It is at this point that following dehydration, you notice a decrease in tears and a change in the balance of the tear layers and a loss of the natural quality of the tears. Dry eye is one of the things that can be irritating and disturbing, Redness and blurred vision and discomfort in the blink are among the symptoms that are present in dry eyes.

In cases where there is dry eye, in fact, the transparency, uniformity and clarity of the eye surface is lost.

When the clarity of the eye is lost, light cannot enter the eye without abnormal refraction and fractures from the surface of the eye. So this is where, in addition to the redness and discomfort of your eyes, sometimes you also feel pain in your eyes and your vision is no longer as clear as before and you have blurred vision.

In these cases, doctors recommend the use of artificial tear drops. There are also special gels that are recommended to be applied on the surface of your eyes at night while sleeping, these gels contain artificial tears. These gels also contain fat components and can keep your eyes moist for a longer period of time and prevent tears from evaporating. But be aware that using these special gels during the day is usually not recommended as it can cause visual impairment while driving.
