What is cloud vision?

While they may appear similar, there is a difference between "cloudy" and "blurry" vision.

  • Cloudy vision makes it look like you're looking at everything through mist or haze.
  • Blurred vision means that what you are seeing is out of focus.

Here we will see the blurred vision that can affect one or both eyes. In addition to feeling like you're looking through a dirty or foggy window, cloudy vision can also include:

  • Blurry vision
  • Seeing faded colors or halos around lights
  • Vision problems at night.

Blurred vision can be temporary, as a result of a minor problem, such as blurred vision, or it can be permanent if not treated with surgery, such as a cataract .


There are many different conditions that can cause blurred vision, ranging from mild to severe and common to rare. Here's what you need to know about these conditions, including symptoms other than blurred vision.

Common causes


Blurred eyes are one of the most common causes of blurry and blurry vision. They can appear as wavy lines, spots, or other shapes that move across your sight.

Most of the time, floaters are not a cause for concern and go away on their own. But if many of them appear suddenly or lead to loss of central peripheral vision, it's time to see a doctor.

Trauma, infection, or inflammation

Sometimes blurred vision can be due to:

Seek medical attention to treat an underlying medical condition to treat blurred vision.


For mild cataracts , the person may initially have no symptoms. But ultimately, the most recognizable signs of this condition are blurred vision and a cloudy lens that is visible to others. This is the result of the breakdown and clumping of proteins in the eye. The bumps appear as cloudy spots on a person's lens, known as cataracts.

Other cataract symptoms include:

  • Colors look washed out
  • Poor night vision
  • Lamps, sunlight, or headlights seem too bright.
  • Halos appear around the lights
  • Double vision
  • You often have to change your prescription for glasses.

Rare causes

Fuchs' dystrophy

Fuchs' dystrophy is a disease of the cornea that occurs when cells in the inner layer of the cornea die. This leads to fluid build-up in the cornea and the person's vision becomes blurry or unclear.

There are two stages of Fuchs' dystrophy . In the first stage, many people do not notice any symptoms, and if they do, it is blurred vision when they wake up in the morning.

Stage 2 symptoms persist for a day and may include:

  • Grit or gritty sensation in the eyes.
  • Increased sensitivity to bright light.
  • Eye problems are worse in humid areas.
  • Very blurred or blurred vision due to a scar in the center of the cornea

Macular degeneration

Age-related macular degeneration occurs when the macula at the back of the eye begins to break down. Symptoms of this condition can include:

  • Cloud vision
  • Blurry vision
  • Empty or dark spots in the field of vision
  • Waves or curves appear in straight lines

Diabetic retinopathy

Diabetic retinopathy is an eye disease that can cause blurred vision or vision loss in people with diabetes.

While the early stages of diabetic retinopathy are generally not accompanied by noticeable symptoms, the later stages may experience vision changes or the appearance of floating dark spots or cobweb-like stripes.

When to contact a healthcare provider

Whenever you experience any vision problems, including blurred vision in one or both eyes, it is a good idea to see your doctor to make sure your eye or eyes are okay.

In addition to blurred vision in one or both eyes, get a comprehensive exam by an optometrist or ophthalmologist if you have:

  • Problems showing objects with peripheral vision.
  • Vision problems at night or reading.
  • Gradual loss of visual acuity.
  • Difficulty distinguishing colors.
  • Blurred vision when trying to see near or far objects.
  • Diabetes or a family history of diabetes
  • Itching or discharge from the eyes
  • Vision changes that appear to be related to medication. (However, don't stop taking or change your medicine without talking to your doctor.)

When is sudden blurred vision in one eye a medical emergency?

In some cases, sudden blurred vision in one or both eyes can be a sign of something serious and requires urgent medical attention. This includes:

  • Partial or complete blindness in one or both eyes, even if it is temporary.
  • Double vision, even if it's temporary.
  • Sensation of a shadow being thrown over the eyes or a curtain falling from the side, top or bottom.
  • Suddenly blind spots appear, halos around lights, or distorted vision.
  • Sudden blurred vision with pain in the eyes, especially if the eye is also red. A red, painful eye with blurred vision is a medical emergency.

Watch out

Treatment for blurred vision in one or both eyes depends on the underlying cause. For instance

  • For cataracts: surgery is the only option.
  • For Fuchs' dystrophy: there is no cure, but depending on the severity of the case, it can be treated with eye drops or corneal transplantation.
  • For macular degeneration: There is no cure, although it is generally treated with certain dietary supplements, anti-vascular endothelial growth factor, and photodynamic therapy.
  • Diabetic retinopathy – can be treated with eye injections, laser surgery, or other types of eye surgery.

Get the word of drug information

Cloudy vision is bothersome, but it can also be a sign that something more serious is happening to your eyes. Pay attention to when the blurred vision started and how long it lasts, and be sure to provide this information to your doctor. And if blurred vision is accompanied by any of the symptoms listed above, seek the necessary medical attention as soon as possible.
