Why Is My Vision Fuzzy

What Are The Causes Of Blurry Vision

What causes blurry vision?

Narrowing down what kind of blurred vision you have can usually make it easier to work out the cause. Possible causes include:

  • Images that appear out of focus and hazy, either close up or far away, indicates either long or short-sightedness. Long sightedness is when objects close up appear blurred, and short-sightedness is when objects in the distance look blurry.
  • Cataracts this causes vision to blur and become cloudy
  • Glaucoma this is a condition where a sudden or gradual increase in pressure in the eye damages the optic nerve at the back of the eye. This can cause tunnel vision.
  • Diabetes high blood sugar can cause the lens of the eye to swell, causing blurring
  • Chronic eye strain this can cause both blurry and double vision
  • Keratitis this is the inflammation of the cornea of the eye
  • Dry eyes vision can fluctuate with this condition
  • Astigmatism this is when the cornea or lens of the eye isnt completely round. This means that light entering the eye is not properly focused onto a single point on the retina
  • Eye injury this includes getting something stuck in your eye, like a small piece of glass, a knock to the eye, eye socket, or area around the eye, or getting chemicals in your eye.
  • Macular degeneration this is when part of the retina becomes damaged over time, and is the leading cause of loss of vision in older people.

It is always best to see your GP to get a diagnosis of the cause of your blurry vision in order to receive the appropriate treatment.

Other Factors Causing Blurry Vision


People with myopia , which can cause blurred vision when looking at objects in the distance, will usually squint their eyes to see those objects in the distance clearer. Myopia can then further strain their eyes and cause other symptoms, such as headaches.


Hypermetropia, or hyperopia, most commonly known as farsightedness, is the opposite of myopia. Hypermetropia occurs when objects in the distance are usually seen clearly, but nearby objects are not. These nearby objects appear blurry, so the eye muscles will overcompensate, which can result in eye strain and eye fatigue when trying to focus on seeing the near object clearly.


With astigmatism, near and far distances can appear to be blurred. This is caused by a refractive error in the lens, which can be a result of an irregularly-shaped cornea. The eyes of people with astigmatism do absorb light rays, but those light rays do not land on the retina , which results in blurry or distorted vision.


Presbyopia is an age-related eye condition. The blurred vision occurs, like with hypermetropia, when focusing on nearby objects. Due to the lens losing its elasticity, accommodation becomes harder, making it difficult for you to read fine print, newspapers, or text on mobile and on computer screens. These symptoms tend to become more prevalent as you age.

When To See An Eye Doctor For Blurry Vision

If you have mild blurry vision that comes and goes, this could mean simply tiredness, eye strain or over-exposure to sunlight.

It could also mean your vision prescription needs to be updated. Or it could mean youve developed a refractive error and are in need of vision correction. If your blurry vision lingers and doesnt improve with rest, time away from screens and getting out of the sun for a while, its time to see an eye doctor.

Sudden or continuing changes in vision such as blurriness, double vision, tunnel vision, blind spots, halos or dimness of vision could be signs of a serious eye disease or other health problem.

If you have sudden changes to your vision, including blurry vision, you should always see an eye doctor near you immediately.

Getting A Diagnosis For Blurred Vision

Its important to get a diagnosis for blurred vision as soon as possible, especially if it’s come on suddenly and/or you have other symptoms. See your optometrist or GP for further investigations.

They will ask you questions to determine your exact symptoms, such as when you first noticed your vision was blurry and what makes your blurred vision better or worse. They may also ask about your medical history and your family’s medical history.

Next, they may examine your eyes and check your vision by asking you to read an eye chart. Other investigations they may carry out include:

  • Tonometry to measure the pressure in your eye

Go straight to your nearest A& E department if you also have:

  • A sudden change in your vision
  • Facial drooping, problems speaking or loss of muscle control
  • Had an accident affecting your eyes
  • Severe eye pain
  • Visual disturbances, such as flashing lights, halos, shadows or spots

Some of these symptoms overlap with the symptoms of a stroke.

  • Facial drooping, problems speaking or loss of muscle control

Natural Loss Of Up Close Vision

Why is my vision blurry even with glasses?

Everyone at some point in their life will require reading glasses, bifocals, progressive glasses or just simply need to take off their glasses to see things up close. This is something called presbyopia and happens starting in our 40s.

This loss of up close vision occurs due to the natural lens inside our eye no longer being able to focus. As this lens loses its focusing ability, things start to become more blurred up close.

Lasik cant reverse presbyopia. After lasik, the lens inside your eye will still have the same trouble focusing.

But lasik does change the prescription of the eye – and this can change how presbyopia affects your vision.

This is especially important for those who are nearsighted before lasik. Nearsighted individuals dont have any issues seeing up close without any glasses . Notice in the first paragraph, I mentioned need to take off glasses to see things up close. This is the exact situation that applies to nearsighted individuals.

Nearsighted individuals who are starting to lose their up close vision may find that they cant see as well up close in their glasses and so they take off their glasses in order to see things up close.

What Can Be Done About Residual Prescription

Top 5 Causes of Blurred Vision, Symptoms, and Treatment

Fortunately, there are ways to correct residual prescription after lasik. It is called a lasik enhancement.

Once your prescription is deemed to be stable , the surgeon will typically lift the lasik flap back up and do an additional treatment with the lasik laser. This is typically called a lift-flap enhancement .

Its a relatively straightforward procedure with a recovery very similar to what you experienced after your original lasik procedure.

Getting your prescription back on target after a lift-flap procedure has a high chance of success. If we return to the golf putting analogy, we are trying to sink a tap-in rather than a 100 ft putt. An enhancement is a much smaller prescription less change in the cornea and thus less that variability can affect.

You Sleep With Your Contacts In

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

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.

Do You Need To See Your Doctor

You dont need to see a doctor when blurriness goes away after blinking or rubbing your eyes, or when its sporadic with a clear cause.

But you shouldnt ignore unexplained, persistent blurry vision, or vision problems accompanied by other symptoms. Make an appointment with your doctor for a diagnosis.

How Is It Treated

It’s important to treat uveitis right away so it doesnât permanently scar your eye or lead to other serious problems, like glaucoma or cataracts.

Your doctor may give you steroid eye drops to ease the swelling, redness, and pain. Steroid shots or pills are other options. In addition the doctor may ask you to take eye drops like atropine which dilate your pupil and prevent painful spasm of your eye. This can make your vision blurry and sensitive to light.

Doctors can treat some types of the condition with a small capsule that slowly releases steroids inside your eye. This is usually a treatment for long-lasting cases. Many of these cases are in just one eye. But with this treatment, you can be more likely to get cataracts or glaucoma. The surgery to put the capsule in your eye wonât require a hospital stay. If your doctor recommends this option, ask them what you can expect.

If you take oral steroids for a long time, you may have side effects, like cataracts, stomachulcers, bone thinning , diabetes, and weight gain. Ask them how the treatment may affect you.
