Blurred vision can be related to various things, but in many cases, it is a sign of a refractive error like nearsightedness, farsightedness, or astigmatism. Another common cause of blurry vision is presbyopia, which is an age-related condition many of us will experience within our lifetime. However, clouded or milky vision impairment is usually a sign of cataracts. Each of these conditions tends to have a gradual progression, as vision becomes a bit more out of focus over time.

Please note: if your vision has become blurry very suddenly, please see an eye doctor immediatelyit could be a sign of a more serious health condition.

If you are experiencing blurry vision, it is possible you may have one of the vision problems noted above. More information about each of these concerns and how they are typically corrected is below:

Keep in mind that blurred vision can also potentially be related to a variety of other conditions, such as glaucoma, diabetic retinopathy, macular degeneration, and more. Additionally, pregnancy, migraines, and other changes to your body and/or health can sometimes affect your vision.

In any case, it is extremely important to see a skilled and experienced eye doctor to obtain a proper diagnosis and appropriate treatment as soon as possible.

Why Is My Vision Blurry Here Are 6 Possible Reasons

According to most sources, blurry, unclear vision is the most common eyesight problem in children and adults. Sudden changes in eye sight can be alarming. Luckily, its usually nothing to worry about. Though, that isnt to say that it cant cause some concern. In this blog post we talk about the major causes of blurry vision. If you or someone you love is worried about their blurred vision, hopefully this can provide some helpful answers!

1. You might need glasses, or you might need a new prescription.

Sometimes the curve of the eye disturbs the angle at which light hits the retina, and this produces a blurry picture. We call this issue myopia, or nearsightedness. It can also be a sign of hyperopia, or farsightedness. Astigmatisms are another common refractive error. These conditions can be remedied with corrective glasses or contacts, or an update to your prescription. For some people, LASIK surgery also proves to be a good solution.

2. You might have conjunctivitis.

3. You might have presbyopia.

4. You might have slept with your contacts in.

Contact lenses move across the eye with every blink, creating tiny scratches. Normally the body has no issue immediately repairing these microscratches, but with your eyes rapid movement while dreaming and the extended period of the contacts being in, the damage can be enough to allow microorganisms in and get into the scratches, causing infection.

5. You might be developing cataracts.

Conditions Related To 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.

Conjunctivitis Or Corneal Abrasion

Are you waking up with your eyes fused shut? Are they leaking fluid that sort of looks like pus? Is your entire eye pink? You might have conjunctivitis, also known as pinkeye.

You might have gotten this infection from handling your contacts with dirty hands. If you’ve got discharge and blurry vision, try holding a clean, warm washcloth over your eyes. Do this for a few minutes several times a day. If symptoms persist, you may need to contact your physician.

Corneal abrasions are common, occurring when something sharp gets between your contact lens and your eye. It can be anything from a grain of sand to a tiny piece of glass. The problem with corneal abrasions is that they can lead to corneal ulcers if not treated properly. This can lead to severe and permanent loss of vision.

If you have blurred vision coupled with pain or discomfort, remove your contacts immediately and make an appointment with your doctor.

Cloudy Vision Vs Blurry Vision

Cloudy vision and blurry vision may result from some of the same underlying eye problems, such as cataracts. However, theyre different conditions:

  • Blurred vision is when objects appear out of focus or soft around the edges
  • Cloudy vision is when the object looks like its behind a foggy window or layer of haze

Blurred vision is a common symptom of nearsightedness or farsightedness. Both conditions can be treated by wearing eyeglasses or contact lenses.

Blurry and cloudy vision can be caused by conditions that may lead to serious complications, including vision loss if left untreated.

The retina is the back part of your eye where light gets focused, like a movie screen. If something happens to that surface, like swelling or tearing, the picture can be distorted or lost. A family history of retinal disease, poor diet, smoking, previous eye injuries or disease, and health issues such as high blood pressure, high cholesterol, and diabetes can raise the odds of problems like macular edema and a detached retina.

What Are The Symptoms Of Blurred Vision

Blurred vision can affect your entire line of sight or just parts of your vision. This could include your peripheral vision, or how you see to the right or left of your field of vision. You can also experience blurred vision in only one eye.

Other ways to describe blurred vision include clouded or dim vision.

There can be many causes of blurred vision. Examples of common causes are:

  • refractive errors, such as near-sightedness, far-sightedness, or astigmatism

These symptoms are similar to those of stroke.

Additional symptoms that may need immediate treatment include severe eye pain or sudden vision loss.

Vision that slowly worsens or other symptoms of blurred vision may require a visit to your primary care doctor or eye care specialist.

If you dont already have a primary care doctor or eye care specialist, you can browse doctors in your area through the Healthline FindCare tool.

Your doctor will diagnose the cause of your blurred vision by first taking an inventory of your symptoms. Examples of questions they may ask include:

  • When did you first start noticing the blurred vision?
  • What makes the blurred vision worse or better?

They may also ask about your personal medical history as well as a family history of eye conditions.

When To Be Concerned About A Change In Your Eyesight

If youve always had great eyesight and suddenly find yourself blinking or squinting because things seem a little fuzzy, its time for a checkup. Many cases of blurry or cloudy vision are caused by nearsightedness, farsightedness or astigmatism common issues that are typically corrected with glasses or Lasik surgery. However, your changing vision could be an important early symptom of a more serious disease or medical condition.

“Not all cases of blurry vision are caused by problems with the structure of the eye,” said Geisinger ophthalmologist David A. Carl, MD. “Environmental factors, lifestyle factors, aging and disease may also affect how well you see.”


Almost 25 million Americans aged 40 and over have cataracts. By the time they reach 80, more than half of all people have some form of cataracts.

“A cataract is a clouding of the eyes lens, which is normally crystal clear,” said Dr. Carl. “While its more common to develop cataracts as you grow older, age is not the only cause.”

Doctors think that environmental factors such as exposure to UV rays, smoking and drinking alcohol may also increase your chances for developing the condition. Some babies are born with cataracts due to genetic defects, developmental issues or exposure to a disease called rubella during pregnancy.


“Conversely, when blood sugar drops too low in response to medication that increases insulin in the blood, diabetics may experience temporary blurriness,” said Dr. Carl.

An Introduction To Blurry Vision

Blurred vision is when the sharpness of eyesight deteriorates, causing objects to look hazy, fuzzy and out of focus either close up, far away, or both. However, blurry vision can sometimes refer to a range of other vision problems, including:

  • Images appearing faded or cloudy
  • Obstruction of vision this is when it looks like there is something in your eye, obscuring vision. These could be what looks like small floating objects in the eye, or halos of light that make it hard to see clearly
  • Double vision.

Prevention Of Eye Strain

The Link Between Carbs Blood Sugar And Vision

Blurry vision after eating occurs when a rapid increase in blood sugar levels causes the lens of the eye to swell. This changes the shape of the lens, thereby changing your eyesight. Blurry vision, in general, is often one of the earliest symptoms of diabetes.

People without a diabetes diagnosis who experience blurry vision after eating should see a healthcare providerespecially if they have diabetes risk factors. Left unchecked, diabetes can lead to serious complications, including blindness.

This article discusses the causes of blurry vision after eating and explains why it occurs. It also explains diabetic eye complications and treatments.

Symptoms Of Blurred Vision

Oftentimes, patients experience a number of symptoms along with blurry vision. In addition to the symptoms mentioned above, other symptoms can include:

  • eye pain
  • loss of central or peripheral vision
  • poor near vision

If you experience blurred vision along with sudden nausea, stiff neck, severe headache, and/or vomiting, call 9-1-1 immediately.

  • difficulty reading the blackboard at school
  • sitting very close to the television
  • poor posture while reading

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

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, according to the NEI.

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.

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.

When To Seek Medical Advice

Blurred vision is often not a serious risk to health and can be easily managed or treated. However, some causes of blurred vision are more serious so it is important you go to your optician to get an diagnosis. After that they can advise you on what course of treatment you can take. These may include surgeries, diet control, eye drops or simply using glasses to correct your vision.

If you experience a sudden onset of blurry vision or seeing double, if your blurry vision is severe, or if you experience pain in your eye or eyes or severe headaches, you should seek medical advice right away.

Fluid Is Building Up In Your Eye

That can put pressure on the optic nerve and damage it. If you’re also seeing halos around lights, your eyes are very red and hurt a lot, and you feel queasy, you may have a type of glaucoma called acute angle closure glaucoma. It develops very quickly, and you could lose your vision within a day if it’s not treated. Open-angle glaucoma is more common, but it doesn’t usually affect your vision at first, because it progresses very slowly over time. Once glaucoma affects your vision, there is no way to get that vision back because your optic nerve has been permanently damaged. The best way to prevent damage is to be diagnosed early by seeing your doctor regularly, who will monitor your eye pressure. If itâs too high, they may recommend eye drops or surgery to lower the eye pressure into a safe zone to prevent damage and vision loss.

Eye Drops And Medication

Health: Why You Might Be Experiencing Blurry Vision

Certain eye drops can cause irritation and blurry vision when used repeatedly. This is especially true with eye drops containing preservatives.

Also, some medications such as allergy pills can cause side effects of dry eyes and blurred vision. Your optometrist or ophthalmologist can advise you whether any of your medications might cause blurry vision.

You Have An Eye Infection

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.”
