Blurry Vision Out Of Nowhere

Could It Be Diabetes

Blurry vision, brain fog, and increased ocular pressure, due to Intracranial Hypertension

The condition raises your risk for an eye disease called diabetic retinopathy. Over time, high blood sugar can damage the tiny blood vessels in your retina, the part of your eye that senses light. That can lead to swelling in a part of the retina called the macula, new and unwanted blood vessels growing in the eye, and bleeding inside the eye.

Along with blurry vision, diabetic eye disease may also cause:

  • âFloatingâ spots in your field of vision
  • Permanent loss of vision

Early treatment is the best way to ward off permanent damage. So protect your eyes from diabetes by getting them checked at least once a year. Learn more about the symptoms of diabetic retinopathy.

Blurred Vision And Enlarged Pupils

Last Editorial Review: 6/15/2020

There are a few different medical conditions that are strongly associated with:

  • Enlarged Pupils

While the symptoms above can be considered a guide to help associate symptoms common among the conditions below, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms. Below are the top condition matches for your symptom combination from MedicineNet:

Why Does Everything Seem Darker In One Eye

Darkened vision sometimes affects a single one of your eyes. If you have optic neuritis, for instance, you may experience problems in either eye or both eyes. Keep in mind that your symptoms may develop due to being exhausted or overheated.

While cataracts often impact both eyes, they can sometimes occur in one. Consider that your symptoms might be more severe in one eye, making your vision appear darker.

Retinal detachment tends to affect one eye, though it can happen in both. Some people, including those with connective tissue problems, may have an increased risk for retinal detachment in two eyes.

You Have High Blood Pressure

You may already know that high blood pressure can lead to stroke and heart disease. What you may not know is that it can also cause a mini stroke of the eye called vein occlusion.

“These patients feel no pain,” said Dr. Shah. “They will wake up and their vision is blurry.” Blurry vision due to vein occlusion usually strikes just one eye, added Dr. Shah.

Treatments for vein occlusion, including medication to ease swelling of the macula, need to be given right away in order to be effective. Even then, you may lose some of your sight.

To protect against vein occlusion, if you’re over 50 and have high blood pressure, Dr. Shah recommended getting regular eye exams.

Treatment Of Sudden Blurry Vision

36 Health Symptoms You Should Never Ignore

To determine proper treatment for sudden blurry vision, you need to understand the cause. For example, if you know that your body is dehydrated and needs water and rest, you can simply drink plenty of water to rehydrate your eyes and relieve them from dry eye and irritation.

Similarly, a good solution for sudden blurry vision due to eye strain is simply resting the eyes. Try the 20-20-20 rule: Focus on an object 20-feet away for 20 seconds every 20 minutes. Blinking is also important because it moistens your eyes to prevent dryness and irritation.

Other causes of sudden blurry vision may require medical intervention. If you have cataracts, for instance, your eye doctor may recommend an outpatient procedure during which the lens will be replaced, resolving the sudden blurry vision issue.

A more serious condition like a detached retina may also require surgery. You should always talk to an eye doctor to determine the cause of your sudden blurry vision before attempting to treat your sudden blurred vision.

How Will Your Healthcare Provider Find Out Why Your Vision Is Blurry

To find out why your vision is blurry, a provider will ask you questions, such as:

  • Do you have any other illnesses like diabetes, hypertension, HIV/AIDS, sickle cell anemia or lupus?
  • Can you describe what you mean when you say your vision is blurry?
  • Do you have any other symptoms? These include things that are vision-related, like eye floaters, or other physical signs and symptoms that may be related to a certain disease or condition.
  • Did you have an injury from an event like a fall?
  • Are you taking any kinds of medications that can affect vision, like steroids?

Your healthcare provider will do an eye exam and may do a physical exam. They may also suggest additional testing.

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.

Vision Problems Linked To Multiple Sclerosis

Vision Loss

This happens when the optic nerve which connects the eye to the brain gets inflamed. It is called optic neuritis.

About half of people with MS will have the condition at least once. It’s often the first sign that someone has the disease. But other conditions can cause optic neuritis, so it doesnât always mean that a person has or will get MS.

Symptoms of optic neuritis usually come on suddenly. They include:

  • Blindness in one eye for a short time, especially during an MS flare
  • Pain with eye movement)

It’s rare to get this condition in both eyes at once. Vision loss tends to get worse for a few days before it gets better. The inflammation could last anywhere from 4 to 12 weeks.

If you start to have any symptoms, let your doctor know. IV steroids are generally used to treat the first episode of optic neuritis, but studies suggest that the use of low-dose oral steroids may increase the chance of a recurrence. Although the symptoms can be disturbing, the best treatment may be no treatment at all.

Double Vision

This happens when the muscles that control eye movement are not coordinated because one or more of them is not working properly. In MS, the problem occurs in the part of the brain that controls the nerves that go to these muscles. It may be worse when youâre tired or you strain your eyes, so try to rest them throughout the day.

Extreme Redness Or Swelling

How Eyes Work and Why Some People Have Blurry Vision?

In many cases, redness and swelling are caused by something relatively easy to treat, such as dry eye syndrome or conjunctivitis , Podoll says. But an extremely red or swollen eye can also be a sign of a more serious condition, so its important to get it checked out.

The most concerning culprit would be an inflammatory condition of the eye, such as uveitis or scleritis. Infection or injury can cause both conditions, but they are most often associated with autoimmune disorders like rheumatoid arthritis or lupus, Podoll says. Other symptoms of scleritis and uveitis include extreme light sensitivity and blurry vision.

Both uveitis and scleritis can cause permanent vision loss if theyre not treated.

What Is Blurry Vision

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. Blurry vision can also be a symptom of more serious problems.

These problems may include a potentially sight-threatening eye disease or neurological disorder. Blurred vision can affect both eyes, but some people experience blurry vision in one eye only.

Cloudy vision obscures objects and causes vision to appear milky. It is similar to blurry vision and is sometimes indistinguishable. Cloudy vision is usually a symptom of specific conditions such as cataracts.

Can Diabetes Lead To Blurred Vision

Yes. It can lead to blurred vision through two mechanisms. Non-permanent damage can occur when the high blood sugar in the blood causes more fluid to flow into the lens of the main. More permanent damage to the small vessels of the eye can cause irreversible changes in vision. The threat of irreversible vision damage

What Causes Blurry Vision

There are many causes of blurry vision, and although the majority are not alarming, its important to know that there are some potentially life-threatening conditions behind this symptom.

Usually blurred vision is caused by refractive errors, including nearsightedness , farsightedness , astigmatism, or presbyopia .

Other times, it could be due to low blood sugar or the onset of diabetic retinopathy in diabetics, or to treatments for certain medical conditions . It can even be caused by laser or other surgery for your eyes.

Some people wear contacts longer than they should, causing proteins and other buildup to cloud the lens and affect vision.

  • Some other common causes of blurry vision include:
  • Age-related macular degeneration
  • Eye infections or conditions, such as infectious retinitis
  • Scarring or abrasions to the cornea
  • Injury to the eye

You might find that everything in your entire field of vision is blurry, or you might notice that your blurred vision only affects a part of your vision, such as your peripheral vision.

Blurry Vision: Causes And Treatment

blurry vision, blurry vision question and answers
  • Myopia. Blurry vision in on eye or both eyes may be a symptom of myopia , along with squinting, eye strain and headaches. Myopia is the most common refractive error and causes objects in the distance to become blurred. Eyeglasses, contact lenses and refractive surgery such as LASIK and PRK are the most common ways to correct nearsightedness.

  • Hyperopia. Blurred vision from hyperopia is when distant objects can be seen sharply but your eyes can’t focus properly on close-up objects or doing so causes unusual eye strain and fatigue. In cases of severe farsightedness, even distant objects may appear blurred. Like myopia, hyperopia can be corrected with eyeglasses, contact lenses or refractive eye surgery.

  • Astigmatism. Blurred vision at all distances often is a symptom pf astigmatism. A type of refractive error, astigmatism usually is caused by an irregularly shaped cornea. With astigmatism, light rays fail to come to a single focus point on the retina to produce clear vision, regardless of how far away the viewed object is from the eye. Astigmatism, like nearsightedness and farsightedness, can be corrected with eyeglasses, contact lenses or refractive surgery.

  • Chronic dry eyes. Dry eye syndrome can affect your eyes in numerous ways, including blurred and fluctuating vision. While artificial tears can help, more advanced dry eyes may need a prescription medication or punctal plugs to keep the eye lubricated and healthy.

Diagnosis For Blurred Vision

Before determining which solutions fits your needs best, your optometrist will first perform an eye examination to establish the severity of your blurriness. This can provide a clear indication of whether or not treatment is necessary, or if the blurriness can be treated with medicated eye drops or with glasses.

The most common questions your optometrist will ask are:

  • When did you start noticing blurred vision?
  • What do you think worsens or slightly improves the blurred vision?
  • Does anyone in your family have a history of eye conditions?

Your optometrist will then carry out the following examinations:

  • A check of how clearly you can see letters on a chart from distance, alternately covering your right and left eye
  • Refraction tests
  • Examining your external ocular health
  • Examining your internal ocular health
  • Avoiding reading fine print or text in dim light
  • Drinking plenty of water to hydrate and lubricate the eyes

What Can I Do At Home To Treat Blurred Vision

If your healthcare provider has evaluated your blurry vision and is treating any underlying disease, you can try the following to help with blurred vision at home:

  • Get enough rest.
  • Avoid allergens, like smoke and dust.
  • Always wear sunglasses outside in the sun.
  • Always wear eye protection when working or doing hobbies that may damage your eyes.

Common Causes Of Sudden Blurry Vision

Sudden blurry vision is typically caused by a one-time event like a retinal detachment or injury. In addition to sudden blurry vision, these can also trigger other vision-related symptoms, including double vision or light sensitivity . If youre experiencing sudden blurry vision, one of the following common conditions may be the culprit:

  • Eye strain is a frequent reason for sudden blurry vision, especially considering how much time is spent staring at screens and electronic devices.

  • Cataracts are a clouding of the eyes lens which can develop as you age and which can, in turn, cause sudden blurry vision and night blindness.

  • Corneal abrasion, or a scratched cornea, is fairly common and can occur when any foreign substance makes contact with or gets into your eye fortunately, this condition typically heals on its own in a few days.

  • A visual migraine is a headache that may include temporary blurred vision. A visual migraine can occur suddenly and move across your field of view and disappear within 30 minutes. If you experience any blind spots, consult an eye doctor immediately to determine if an underlying condition is happening, such as a retinal detachment.

  • Detached retina occurs when the light-sensitive retina separates from the back of the eye. If not treated, this condition can continue to worsen and lead to irreversible vision loss.

New Or Severe Headache Without Trauma

Some emergency conditions marked by headache and blurry vision can also occur without trauma. If you feel you have any of the following conditions, seek immediate medical help.

Closed-angle glaucoma

In closed-angle glaucoma, pressure in the eye builds up because fluid in the front part of the eye does not drain as it should. This is considered a medical emergency, and you should seek immediate medical attention.

If not treated, the pressure inside your eye can build to the point that it damages your optic nerve, which could result in permanent vision loss.

Closed-angle glaucoma is a rare form of glaucoma. Unlike the more common open-angle glaucoma, this type of glaucoma develops quickly, and its symptoms are obvious.

It is called closed-angle glaucoma because the angle between the iris and the cornea is either closed or very narrow. This most often occurs in older adults, especially those with smaller eyes.

Closed-angle glaucoma affects women about twice as often as men. Symptoms usually come on suddenly and can include:

  • blurred or hazy vision
  • red, flushed skin
  • loss of consciousness

Carbon monoxide poisoning is treated with oxygen, either through a mask or placement in a hyperbaric oxygen chamber. Carbon monoxide poisoning is preventable. Be sure to have a functioning CO detector installed in your home.

Herpes zoster ophthalmicus

Early symptoms of herpes zoster opthalmicus may include:

  • flu-like symptoms

Meningitis and encephalitis

Your Eyes Are Dry Or Mucus

It’s not unusual for eyes to be a little drier or mucus-filled first thing in the morning, Dr. Krauss explains. And both dryness and excessive mucus can temporarily blur your vision.

âFix it:â Blinking a few times is often enough to rehydrate your eyes or clear away any lingering mucus bits, Dr. Krauss says. If that doesn’t work, a few drops of saline solution should also do the trick.

You Have A Rare Eye Infection Or Injury

Blurry vision can sometimes be caused by serious eye problems, including a corneal ulcer, herpes or amebic infections, Dr. Krauss notes. Often the blurriness will occur alongside other symptoms like pain, cloudy vision or a visible spot on your cornea.

âFix it:â Serious eye infections can cause permanent eye damage, so they need swift medical attention, Dr. Krauss says. See an eye doctor right away.
