Health problems are constantly worrying to a greater or lesser extent, but when it comes to vision, it is logical that a little more fear and tension arise. The image’s sensation is suddenly cloudy due to different causes such as a drop in pressure, having slept in a bad posture, or problems in the retina or the nerve of the eye.

If you want to know why your vision is suddenly clouded and know what to do in each case, I recommend that you continue reading this article by FastlyHeal .


Vision can suddenly blur if blood pressure drops below normal. This can commonly happen when standing up abruptly and responding to why your idea is suddenly clouded.

Other symptoms also tend to appear, such as:

  • Dizziness
  • Darkened vision.
  • Even loss of consciousness.


The discomfort usually improves in a few moments and without doing anything. You can help yourself by remaining seated, lowering your head against your chest, or lying down.

To prevent this type of reaction in people with low blood pressure, getting up little by little and drinking enough fluids a day is convenient.

If this happens only once, it is not to worry, but it would be advisable to go to a medical check-up if it is something recurrent.

Sleeping in a wrong position

You may have been sleeping in some strange and uncomfortable position during the night, which explains why your vision is suddenly clouded. Sleeping in a bad situation can cause the nerve that runs from your eye to the brain to paralyze, resulting in blurred vision temporarily.


Usually, this settles in a few minutes, and little by little, it returns to normal. If this happens frequently, it is better to make an ophthalmological consultation.


An inflammation or infection in one or both eyes could cause you to wake up in the morning with cloudy vision even if you had gone to bed completely normal. The most common cause is conjunctivitis, the inflammation or infection of the conjunctiva or layer that covers the eye and the eyelids on the inside.

It is usually accompanied by other symptoms such as:

  • Itchy eye
  • Wet or dry secretions.
  • Sensation of having glued eyes.
  • A cold.


If you think that this is your case and it answers why the vision is suddenly clouded, it is convenient:

  • Clean the eye or eyes with warm water or some infusion with chamomile. Use a clean cotton pad or cloth and discard or wash it. Do not use the same in both eyes or share it with other people, like the towels.
  • Wash your hands well frequently; this way, you will avoid contagion to the other eye and other people.
  • Consult a professional.

Optic nerve problems

Different diseases can cause the nerve of vision not to transmit correctly to the brain. Symptoms may include the following symptoms:

  • Blurry vision.
  • Darkening of vision.
  • Spots in the visual field.

This can be due to problems such as:

  • Vascular problems
  • Infections
  • Trauma
  • Autoimmune diseases.
  • Neurodegenerative diseases.
  • Tumors


If you notice that you have suddenly lost your vision, it is best to go to a specialized ophthalmology center. They will review you and request the studies they consider necessary to make a diagnosis. An early diagnosis is usually more beneficial for the recovery of sight.

Retinal problems

Vision can be suddenly clouded also by a problem with the retina. The retina is one of the layers of the eye, and the nerve cells responsible for transmitting light impulses take place in it.

Different disorders can affect it, such as:

  • Trauma
  • Chronic diseases like diabetes.
  • Myopia suffering.
  • Eye surgery
  • Tumors

Among the symptoms of problems in the retina you can have:

  • Sight loss.
  • Stains insight.
  • Cloudy view.
  • Bright flashes.
  • The vision of “flies” or flying spots.
  • Image distortion.


Treatment will depend on the cause. It may not take more and wait for it to get better on its own, but in other cases, surgical intervention may be required.


Typical migraine headaches can be accompanied by cloudy vision. Sometimes vision changes are symptoms that warn that the migraine will begin; this is known as aura.

The headaches are usually always on the same side of the head, similar to beats, and may be accompanied by discomfort with light, smells, or noise, and nausea may appear too.

These types of headaches usually appear when the person is out of his average balance: he has eaten little or a lot, he has slept badly or too much, or he is going through stressful situations, among others.


The way to improve cloudy vision is to improve migraine. Improving habits, exercising, and eating healthily often significantly improve the situation of migraine sufferers.

Dry Eye

Dry eye is one of the reasons why vision is suddenly blurred. When the hydration of the eye is insufficient, when it is excessively exposed to digital screens or is irritated, the famous dry eye can appear. You will notice that the eye scratches, bother, and vision becomes cloudy.


It is best to go to an ophthalmological consultation to diagnose correctly. In the meantime, you can apply artificial tears or place an ancient Hindu medicine at night: ghee or clarified butter.
