Blurred Vision Comes And Goes

A List Of Common Vs Emergency Causes

What causes sudden blurred vision?

It can be alarming to experience blurry vision, whether it’s gradual or sudden. With causes ranging from mild to severe, it’s can help to understand what might be behind things looking fuzzy out of one of your eyes.

The most common cause of blurred vision is a refractive error. This can cause near-sightedness or far-sightedness. This cause isn’t an emergency, but blurred vision in one eye could be due to glaucoma, a detached retina, an “eye stroke,” and other causes. Particularly if symptoms come on suddenly, you should seek medical attention right away.

Many conditions can result in blurry vision in either one or both eyes. This article will feature conditions that affect only one eye.

Could It Be Parkinson’s Disease

Blurry vision is not the first sign of this nerve disease. But as it gets worse, it can affect sight. That’s because the condition may change how your eyes move. As your sight seems less sharp, you may strain your eyes because they have to work harder to focus.

Parkinson’s disease affects much more than the eyes. It also causes:

  • Poor balance and coordination

Could It Be Multiple Sclerosis

Blurry vision is often one of the earliest symptoms of multiple sclerosis . The disease causes inflammation along the nerve that connects your eyes to your brain, called the optic nerve. That causes a condition called optic neuritis, which can give you blurry sight, loss of color vision, and pain when you move your eyes. It often happens in just one eye.

Besides blurry vision, MS also causes:

  • Trouble with balance

If your doctor thinks you might have a brain tumor, they’ll use different tests to check how well your brain and spinal cord work, as well as imaging tests to see inside your head. Learn more about the different types of brain tumors.

If you have had a cataract removed and your blurry vision reoccurs, posterior capsule opacity also known as a secondary cataract may be the cause.

How Can Blurred Vision Be Prevented

You probably cant prevent blurred vision at all times, but you can help yourself by making sure youre following your providers recommendations if you have a condition like diabetes. You can also help yourself by developing and maintaining a healthy lifestyle that includes nutritious foods and physical activity. Make sure to have regular eye exams.

You Sleep With Your Contacts In

If you don’t use contact lenses properly, they can cause sight-robbing infections.

Contact lenses move across the eye every time you blink, creating micro-scratches on the surface of your eye. Infection-causing microorganisms can get caught under the lens and get into the scratches.

Sleeping with your contacts in, said Dr. Le, “is a perfect petri dish to grow those organisms and cause corneal ulcers,” open sores on the cornea that can blur vision.

“Always, always take out at night,” added Dr. Shah, or toss disposable lenses at the end of the day.

Rheumatoid Arthritis & Sjogrens Syndrome

Blurry Vision: The Causes and When It’s Necessary to See A Doctor

Rheumatoid arthritis itself often appears alongside Sjogrens syndrome, another autoimmune disorder that attacks the moisture glands in your eyes and mouth, causing them to struggle with normal function.

This attack on moisture glands can lead to dry eye syndrome, which might also affect the outer vision-focusing surface, called the cornea. Some patients with dry eye symptoms trace the cause back to autoimmune disorders.

You can help control blurry vision with dry eye therapy. Annual eye exams manage your ocular health and identify when autoimmune disorders are affecting your vision.

Causes Of Blurred Or Distorted Vision

  • Are you having trouble seeing things clearly to the point that its interfering with your day-to-day? Blurred vision is a common issue that many people deal with at one point or another. It may be benign and short-lived, or it could be indicative or something more serious.

    Any sudden change in vision is a concern that should be addressed as soon as possible with an eye doctor. On the other hand, a gradual deterioration of vision marked by blurring could simply be part of a natural, age-related change. Regardless of the severity, its important to address the change so that you can identify the cause and weigh treatment options.

    Here are nine common causes of blurred vision:

  • Prevention Of Eye Strain

    You can help prevent dry eyes and minimise the risk of tired or sore eyes while reading or using a computer. Tips include:

    • Take regular breaks.
    • Look around at objects that are at different distances.
    • Remember to blink often.

    If this doesnt help, see an optometrist to find the underlying cause of the problem. Treatment may include eye drops, exercises or glasses.

    Ocular Symptoms And Conditions: Blurred Vision

    Blurred vision can come about from any disturbance in the pathway of light from the front of the eye to the retina. Disorders of the optic nerves which transmit visual information to the brain can also be a source of blurred vision. A change in vision can be as simple as a need for glasses, but in some cases more complicated reasons for blurred vision can be present, and a complete eye examination may be necessary to determine the cause.

    This page discusses causes of blurred vision that normally have very few other symptoms. Some of these conditions can cause more than just blurred vision, they may cause a loss of vision. Conditions which usually cause a more severe loss of vision are discussed on the Loss of Vision page. Many other eye problems can cause blurred vision along with numerous other symptoms. Links to these Symptom and Diagnosis pages based on these other symptoms are included as well.

    You Have An Eye Infection

    Vision Slightly Blurred

    You don’t have to wear contact lenses to get eye infections that damage the cornea.

    Herpes keratitis is an infection in the eye caused by the herpes virus and is the most common cause of corneal infections, according to the CDC.

    You can get it just by touching a cold sore on your lips then touching your eyes. Bacteria and fungi that muscle their way in after an eye injury can also cause infection.

    Treatments like eye drops and medications usually help. But the best method of protection from eye infections is prevention.

    Your cornea will do a lot of the preventative work for you. “The cornea is an amazing structure,” said Bibiana Reiser, MD, assistant professor of ophthalmology at the Keck School of Medicine, University of Southern California and director of cornea and glaucoma services at Children’s Hospital of Los Angeles.

    “It has a lot of that kill things directly on contact.”

    Intra-ocular pressure is another possible cause of decreased vision in one eye. Often, this occurs in the morning. You are therefore advised to calmly take a deep breath. You can also visit your health specialist for a checkup since sometimes the cornea can isolate from the eye socket lining.

    This can also be as a result of allergic reactions with foreign objects such as dust particles. Dry eyes can reduce your eyesight. In such cases you are advised to use artificial tear drop, have sufficient rest and enough sleep.

    Fluctuating Vision Causes And Concerns

    Posted under Living With Low Vision, Low Vision Info

    Fluctuating vision is a common concern for those with chronic eye diseases. One day your vision may be sharper and clearer than normal and the next its blurred and the clarity seems to have disappeared. My vision fluctuates from day to day or I notice differences from day to day and some days my eyes are dry, tired and blurry are common statements from those who have macular degeneration. The fluctuation can even be tied to the time of day for some morning is when they experience the most loss of visual acuity and for others its at the end of the day. Fluctuating vision can be described as having good or bad vision days, or noticing the changes in quality of vision between the morning and the evening. These experiences are not caused by the environment , but rather are physiological in nature, explains Terri Cyr, OD and author of Insight Into Low Vision.

    What causes these fluctuations or temporary changes in vision? There is normally more than one contributing factor but here are some of the more common ones:


    Diabetes damages the lining of blood vessels and especially the susceptible tiny blood vessels of the eye which can lead to diabetic retinopathy. Diabetics will notice a change in their vision when their blood sugar levels are not well controlled.

    You Have A Rare Condition Called Uveitis

    If your eye blurriness and dryness are accompanied by inflammation in or around the eye, you could have uveitis.

    The inflammation usually happens when your body is fighting an infection or you have an autoimmune disease, according to the NEI. The most common causes of uveitis arecorneal abrasion/ eye trauma, infection, and autoimmune disease.

    The prevalence of uveitis is pretty low, but the damage can be quite severe, said Dr. Diaz. Symptoms vary depending on what part of the eye is affected

    “Inflammation in the front part of the eye presents with redness, light sensitivity, and pain, whereas inflammation in the back part of the eye presents with floaters, fuzzy vision, and flashing lights,” explained Dr. Diaz.

    According to the NEI, treatment for uveitis usually involves steroids given in some form, from pills and eye drops to injections and implants.

    Conditions Related To Blurred Vision

    Mahogany L. Browne – Blurred Vision

    The cone cells on the macula become damaged, leading to loss of central vision. There are two main types: dry AMD, which progresses slowly but is untreatable, and wet AMD, which progresses more rapidly but is treatable, especially if spotted early.

    Cardiovascular disease

    Blurred vision that occurs with double vision can be a sign of a health emergency, such as a brain haemorrhage or stroke.

    A cataract is the gradual clouding of your lens, which is a transparent disc behind your iris . Its common in people over 65, though it can happen earlier. Besides blurred vision, symptoms include sensitivity to light and a dulling effect on colours. Luckily, its easily treated with cataract surgery.


    Over time, diabetes can lead to a condition called retinopathy, when the tiny blood vessels at the back of your eye become blocked and leak. This damages your retina, which is essential for vision and can lead to sight loss. However, it can be prevented if detected early through regular screening.

    There are four types of glaucoma, which can lead to a build-up of pressure in your eye, damaging the optic nerve. This can permanently damage your sight, especially your peripheral vision, but once its detected, sight loss can usually be prevented.
