14 Common Causes of Blurry Vision & What to Do Next

Even though blurry vision is a common issue, it isn’t something that you should brush aside. If you are experiencing vision changes, it could indicate that you need to talk to an eye doctor.

Vision can be blurred temporarily or permanently, depending on the cause of blurry vision. Here are some of the most common reasons affecting your vision – broken into two categories: immediate/emergency treatment and other causes.

5 Causes of Vision Emergencies

A sudden occurrence of blurry vision could be an indication of an eye emergency. In these situations, it’s essential to seek medical care as soon as possible to minimize vision loss and prevent permanent damage to your eyes.

Causes of vision emergencies might include:

  1. Retinal Detachment: The delicate retinal tissue in the back of the eye can tear away from the wall, resulting in a loss of nerve and blood supply to the tissue. You’ll experience symptoms such as blurry vision, flecks, and flashing lights. Emergency treatment is essential to avoid permanent vision loss.
  2. Stroke: The blurred vision might not be caused by an eye issue, but instead, it is a problem happening with the brain. A stroke can affect the area of the brain that controls vision and might affect either one or both eyes.
  3. Glaucoma: A specific type of glaucoma, known as angle-closure glaucoma, is a condition that affects the drainage system in the eye. As a result, the pressure builds up quickly, resulting in pain, redness, and blurred vision.
  4. Macular Degeneration: The macula is located in the center of the retina. If abnormal blood vessels start to grow, it can cause fluid and blood to leak into the macula – causing blurry vision. This condition can happen suddenly and have rapid progression.
  5. Eye Injury: An accident or injury can cause blood to pool in the front of the eyeball, known as a hyphema. This condition can cause blurred vision and increasing pain due to the building pressure.

A comprehensive eye exam is necessary to identify the specific cause of your blurred vision. If you are experiencing any sudden symptoms affecting your vision, call our office right away – or head straight to the emergency room if you suspect a stroke or serious medical condition.

9 Other Causes of Blurry Vision

Sometimes, vision can start to blur gradually. These non-emergency conditions still require diagnosis and treatment from an eye doctor. Causes of blurred vision might include:

  1. Eye Strain: How much time do you spend looking at a screen each day? People who work at the computer have a higher risk of eye strain. Causes of eye strain can include looking at a cellphone or computer too much or driving and reading in poor light conditions.
  2. Blood Sugar Fluctuations: When the blood sugar levels change in the body, it can affect vision. For example, high blood sugar causes inflammation and swelling, which can result in blurred vision.
  3. Infection: Certain types of eye infections can affect your vision. For example, pink eye (conjunctivitis) can cause inflammation on the eye lining, which can impact your vision. Usually, this blurred vision is temporary, but it’s essential to seek medical treatment to avoid long-term complications.
  4. Scratched Cornea: The clear covering over the front of the eye is known as the cornea. If this area is scratched, then the abrasion can affect your vision. Not only do you have blurry vision, but it probably feels like there is something in your eye.
  5. Autoimmune Condition: Certain autoimmune health issues can affect eyesight. The autoimmune reaction increases inflammation in the body – which can affect the eyes.
  6. Corneal Inflammation: Keratitis is a condition that usually happens because of an eye infection and can cause blurred vision. Common causes of this inflammation include infections from using dirty contact lenses or wearing contacts too long.
  7. Optic Nerve Inflammation: The optic nerve runs between the brain and the eye and can become inflamed from conditions such as multiple sclerosis or an autoimmune reaction. Usually, this type of blurred vision only affects one eye.
  8. Migraines: Sometimes, migraines can affect a person’s vision. You might have a headache with blurred vision. Or, an ocular migraine can cause visual disruptions without the associated pain.
  9. Change in Prescription: One of the most common causes of blurry vision is a change in your prescription. It’s normal for the eyes to change over time, often causing a gradual increase in blurred vision.

Are Other Symptoms Happening with Blurred Vision?

If you are trying to decide whether you need to talk to an eye doctor, also look for other symptoms that might be happening in conjunction with blurred vision.

These symptoms might be mild, moderate, or severe. Symptoms include:

  • Redness
  • Pain
  • Itching
  • Headache
  • Nausea
  • Double vision
  • Photophobia
  • Floaters (floating specks in your vision)
  • Eye discharge
  • One-sided weakness or speech difficulties (indicating a stroke)

Eye Emergencies: When to Seek Immediate Treatment

Serious eye conditions can result in permanent damage and vision loss. But some of these conditions can improve with prompt medical attention, which is why immediate treatment is necessary.

If you notice any of these warning signs with your blurred vision, then it’s essential to see an eye doctor without delay:

  • Eye injury or accident
  • Signs of a stroke
  • Sudden change in your vision
  • Problems speaking
  • Significant reduction in vision affecting one eye
  • Blurred vision with other health issues, such as chemotherapy treatments or HIV
  • Eye pain
