Jan 04, 2021 Cloudy vision is the loss of visual acuity or a blurring of visual perception that can affect one or both eyes. You may experience cloudy vision as a haziness or lack of clarity in your eyesight. It can be constant or intermittent, and one or both eyes can be affected. Could It Be Diabetes? The condition raises your risk for an eye disease called diabetic retinopathy. Blurry vision is the loss of sharpness of eyesight, making objects appear out of focus and hazy. The primary causes of blurred vision are refractive errors — nearsightedness, farsightedness and astigmatism — or presbyopia. But blurry vision also can be a symptom of more serious problems. “If the visual disturbances are similar to a slow dimming of vision or blacking out of vision, and it lasts for 5-10 minutes, then it is likely caused by a mini-stroke, also known as a transient ischemic attack (TIA).”.
Having cloudy vision can lead to the loss of visual acuity or blurred visual perception. It may affect one or both eyes and feel like a haziness or lack of clarity in vision. Cloudy vision may be a constant occurrence or one that comes and goes. It can also affect color perception and may be accompanied by the perception of halos or glare around light sources.
There are many causes of cloudy vision, with some being more harmful than others. Discharge from the eyes or tearing can lead to the condition, or it could be the symptom of a more serious disorder such as glaucoma or trauma to the eye.
It is important to note that cloudy vision is not the same as blurry vision, despite the terms being used interchangeably. Blurry vision is often caused by a refractive error in the lens of the eye that can be corrected with eyeglasses. Cloudy vision is the gradual loss of transparency of the cornea or lens of the eye, which most commonly occurs in cases of cataracts. Early development of cataracts can occur as a result of injury, diabetes, or prolonged use of certain medication.
What causes cloudy vision?
Various diseases and underlying conditions can lead to the development of cloudy vision. It could be a minor nuisance or lead to permanent vision damage. Additionally, the use of some medications may exhibit side effects affecting eyesight, leading to cloudy vision.
Common causes of cloudy vision include:
- Cataracts
- Diabetes
- Foreign body in the eye
- Glaucoma
- Injury to the eye
- Macular degeneration
- Migraines
- Myopia (nearsightedness)
- Optic neuritis
- Retinal vascular occlusion
Life-threatening causes of cloudy vision:
Sudden Foggy Vision In One Eye
- Brain tumor
- Stroke
- Transient ischemic attack—a small stroke
- Retinal detachment—the detachment of the blood vessels within the eye that provide oxygen-rich blood
- Glaucoma—increasing intraocular pressure that damages the optic nerve
- Optic neuritis—inflammation of the optic nerve
- Corneal infection or injury
Symptoms that can accompany cloudy vision
Cloudy vision is usually a symptom of an underlying condition that presents with a host of additional symptoms that are not eye related. It may lead to a partial loss of vision due to its opaque nature. It could also result in eye dryness, leading to eye irritation, redness, and perhaps double vision. Objects in the distance may become difficult to see in cases of cloudy vision. Photosensitivity or a sensitivity to light may also develop, leading to possible excess tear production.
Cloudy vision may also accompany other conditions such as a severe headache, dizziness, numbness, and confusion.
Treatment of cloudy vision
Depending on your specific case of cloudy vision, it may or may not be treatable. The underlying condition may have already inflicted significant optic nerve damage, limiting vision. However, conditions such as cataracts can be operated on, helping patients to successfully cure their blurry vision.
Most treatment for cloudy vision is focused on preventing further vision loss. The following are various treatments used to help control cloudy vision symptoms and reduce damage.
- High doses of Vitamin A, C, and E are often prescribed to delay the progression of macular degeneration
- Taking prescription medication for delaying age-related macular degeneration
- Being aware of medication side effects that may affect vision
- Avoiding alcohol and cigarettes, both of which are known to contribute to a condition that leads to cloudy vision

We are going to explain why do you see prisms in peripheral vision and how to prevent this condition. Peripheral vision is a part of vision that takes place outside the very center of look. There is a broad set of non-central points in the visual field that is included in the notion of peripheral vision. “Far peripheral” vision refers to the area at the edges of the visual field, “mid-peripheral” vision exists in the middle of the visual field, and “near-peripheral”, often referred to as “para-central” vision, exists nearby to the center of gaze.
Functions of Peripheral Vision
The primary functions of peripheral vision are:
- recognition of popular structures and forms with no have to focus by the foveal line of sight,
- identification of similar forms and movements (Gestalt psychology laws),
- delivery of feelings which form the background of comprehensive visual perception.

Foggy Vision Symptoms
Symptoms Associated with Prisms in Peripheral Vision
About a third of people will get alerting signs hours or days before a migraine. This is called the prodrome or pre-headache stage. You might:
- Have food yearnings.
- Get “hyper” or cranky.
- Be fatigued and yawn more.
- Feel stiff, especially your neck.
- Need to urinate more often.
- Get constipated or have diarrhea.
Auras often start about an hour or so before the headache. They aren’t just distorted vision, however. They can impact any of your senses.
- Trouble finding words or speaking (aphasia).
- Seeing prisms in peripheral vision.
- Seeing zigzag patterns (stronghold spectra).
- Vision loss in part of one or both eyes.
- Blind spots (scotomas).
- Seeing flashing lights (scintilla).
- Seeing, hearing, or smelling things that aren’t really there (hallucinations).
- Prickling, tingling, or numbness (paresthesia).
The aura usually lasts less than an hour. Some symptoms might continue into the headache stage.
Migraine pain is steady or throbs. You generally feel it on the front or side of your head, around the eyes. Adults are most likely to harm on simply one side. The headache may last from an hour to 3 days.
Besides pain, other headache symptoms might consist of:

Pain-relievers like aspirin, acetaminophen, or a non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, may help. Your doctor can prescribe larger doses of NSAIDs.
The prescription medications such as rizatriptan (Maxalt) and sumatriptan (Imitrex) minimize the pain and associated functions.
Other medications can relieve associated symptoms such as nausea and vomiting.
A method called a transcranial magnetic stimulation (TMS), uses a pulse of magnetic energy to promote part of your brain, which might stop or reduce the pain. You’ll require a prescription to get this device, which you place on the back of your head when you experience the aura beginning.
Occasional Foggy Vision
How To Prevent Seeing Prisms in Peripheral Vision Caused By Migraine with Aura
Some drugs that treat other conditions can avoid migraines, too:
What Causes Foggy Vision
- Heart and blood pressure medications called beta-blockers, consisting of atenolol (Tenormin), propranolol (Inderal), and timolol (Blocadren).
- Antidepressants such as amitriptyline (Elavil) and nortriptyline (Pamelor), antidepressants.
- Anti-seizure medications such as topiramate (Topamax) or valproic acid (Depakene, Depakote).
Your doctor may recommend a headband-like device that creates electrical impulses on your skin. When it’s on, you’ll feel a tingling or massaging experience on your forehead. This stimulates the nerve related to migraine headaches. You use it day-to-day to prevent headaches.
Avoid your triggers. Common ones consist of:
- Being tired, sick, or starving.
- Flickering or flashing light.
- Atmospheric pressure or altitude modifications.
- Medications.
- Hormone level changes.
- Stress.
- Foods.

Keep in mind the date and time of the migraine, any foods you consumed, what you were doing, and any medication you took right before the headache started. It might take a number of weeks to start to see a pattern.
