What Does Blurred Vision Look Like

Problems With The Retina

What blurry vision is like.

Light triggers the retina to create electrical signals that get sent to the brain and create the images we see. Damage to the retina is one of the reasons for blurred vision.

The retina houses special cells called rods and cones and allows us to:

  • adjust to darkness

Damage to this delicate area can affect one or more of these abilities. Here are some common problems with the retina that can result in blurred vision.

Tear or Detachment

If the retina tears and/or pulls away from where it should be, you may experience:

  • sudden blurry vision in one eye

Tears and detachments will not heal on their own, therefore requiring medical treatment.

Diabetic Retinopathy

Diabetes makes you 25 times more likely to go blind than somebody without diabetes. This is because the condition affects blood vessels.

What Is Diabetic Retinopathy

This condition occurs when diabetes damages blood vessels in the retina due to frequent high glucose levels.

Warning Signs

You may suffer from this condition if you have diabetes and:

  • you experience blurred vision in both eyes
  • your vision remains blurry even after stabilization of glucose levels
  • experience difficulty seeing color

If you experience these symptoms, your doctor will perform a dilated eye exam to determine the course of treatment.

Treatment Options

Treatment for this condition includes:

  • managing the diabetes
  • light sensitivity

Double Vision Affecting Both Eyes

Double vision affecting both eyes is usually a symptom of a squint.

This is where problems with the eye muscles or nerves cause the eyes to look in slightly different directions.

Squints are more common in children but they do not always cause double vision. An untreated squint in children under 7 causes a lazy eye instead.

Squints in adults are sometimes a sign of a more serious condition.

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

What Are The Causes Of Blurry Vision

There are multiple factors which can cause blurry vision. Some of the most common ones are as follows:

  • Near-sightedness, far-sightedness or astigmatism
  • Injury or trauma to the eyes
  • Infectious retinitis

Some conditions in particular can cause headache as well as a blurry vision. These include migraine, low blood sugar, stroke etc.

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.

What Does A Person With Cataracts See

Cataracts are a natural part of the aging process and result in a thickening of the lens inside the eye. Since it is generally a slow process that occurs over many years, vision changes from cataracts may not be noticeable until the cataracts are fairly progressed.

Vision will become more blurred, and it can often feel as though youre looking through a dirty or fogged window. Cataracts can also cause a yellowing of colors or they can make colors appear duller than they actually are.

Why Do I Experience Blurry Vision In The Morning When I Wake Up

For the most part, blurry vision when you wake up is caused by dried or lack of tears on the front of your eye, it usually clears when you blink a few times as the natural debris is removed, and the tear film refreshes.

Your eyes can dry up as the result of being dehydrated , allergies, sleeping with a fan on, leaving your contact lenses in and even some medications.

Diabetics may wake up with blurry vision as a result of their blood sugar levels altering overnight this may also be linked with feeling dizzy.

If you have blurred vision, you may need to wear glasses or contact lenses.

Difficulty Seeing At Night

What causes blurry vision?

Cataract patients with poor night vision have trouble seeing in dim light or darkness. This means the eyes take a very long time to adjust when going from light to dark. Patients experiencing this cataract symptom struggle in low light conditions such as driving at night and in cinemas.

Have you been staring at a screen or page or focusing on a task for a long time? People tend to blink less often when they’re concentrating like that. And each time you blink, you’re spreading tears across the surface of your eye to keep it lubricated, clean, and refreshed. You may need to remind yourself to blink more often, take breaks, and look around to prevent vision fatigue. It can also be helpful to use artificial tears during the day to help keep your eyes lubricated.

As blurred vision has many possible causes, the treatment will depend on the condition. If the blurring is recurring or ongoing, you should book an eye examination with your optometrist. They will investigate the cause and recommend suitable treatment, or refer you to an appropriate specialist.

If you think it may be one of the symptoms of a serious medical condition such as stroke or pre-eclampsia, you should seek urgent medical help.

Causes Of Diabetic Eye Diseases

At the heart of all diabetic eye diseases are persistently high blood glucose levels. This can directly or indirectly cause damage to the structures of the eyes.

The damage caused to one part of the eye can have a knock-on effect, leading to additional eye complications and/or accelerating the progression of pre-existing eye diseases.

Tired Eyes And Blurred Vision

If you spend a long time using a computer or watching television, your eyes can become tired and your vision blurred.Using a computer does not cause permanent damage to your eyes. However, working on a computer is a demanding visual task that can cause eye discomfort. If you have an uncorrected vision problem, this can make computer use uncomfortable and can lead to blurred vision and eye strain.Whenever you concentrate on a computer screen or watch television, you tend to blink less. This can lead to your eyes drying out. It is made worse if you are in a dry environment, such as a heated or air-conditioned office.

Later Stage Cataract Vision

Left untreated, a cataract will develop to late-stage. It can become visibly noticeable to other people, appearing as a milky spot at the centre part of the eye. Its this that creates the vision impairment. With a late-stage cataract, patients will have very limited vision, may need to stop driving, and may become more reluctant to go out and about alone.

Causes Of Blurred Vision

There are many possible reasons for blurred vision.

Eyesight problems

  • Eye strain caused by looking at something, such as your computer screen, for a long time, or wearing the wrong prescription glasses or contact lenses
  • Refractive errors these can usually be treated with contact lenses, glasses and/or surgery, and include:
    • Astigmatism a distortion of your vision that can make objects at all distances appear blurry, which is usually caused by the front surface of your eye being misshapen
    • Hyperopia this is also known as long-sightedness and causes objects in your near vision to appear blurry other symptoms include eye strain and fatigue
    • Myopia this is also known as short-sightedness, is the most common refractive error and causes objects in the distance to appear blurry other symptoms include eye strain, headaches and squinting
    • Presbyopia age-related loss of your near sight caused by the lenses inside your eyes hardening
  • Wearing your contact lenses for too long this can cause debris in your tear film to build up on your contact lenses

The short answer is: no. Prescription glasses cannot treat or cure cataracts, the only cure for cataracts is eye surgery. However, with the right prescription, glasses or contacts can help to correct issues caused by cataracts in the short term. Some cataract patients develop significant changes in their glasses prescription. Corrective lenses can help with blurry vision and difficulty seeing objects at a distance. Changes to the glasses prescription due to cataracts can happen frequently which can prove expensive in the long run.

Eye Conditions And Diseases

If you have sudden blurry vision in one eye and are over age 60, its possible you have developed a macular hole in the central zone of your retina.

Sudden blurry vision also may be a symptom of a detached retina, eye herpes or optic neuritis .

Certain eye conditions and diseases can cause permanent loss of vision. Its vital to see an eye doctor for diagnosis and treatment if you experience sudden blurry vision.

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

Could It Be Preeclampsia

If you’re pregnant, you shouldn’t take blurry vision lightly. It could be a sign of preeclampsia, a dangerous condition marked by very high blood pressure and protein in your urine. Preeclampsia occurs in women who have never had high blood pressure before and generally occurs late in pregnancy, generally after 20 weeks. It can have serious, life-threatening effects on you and your baby.

Preeclampsia may not cause any symptoms, but blurry vision and other sight changes such as seeing flashing lights or spots could be clues that you have it.

Be sure to contact your doctor if you notice these as well as other possible signs:

  • Anxiety, shortness of breath, a racing heart, or confusion

Conditions Related To Blurred Vision

ASTIGMATISM vision vs NORMAL 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.
