Understanding the Causes of Blurry Vision in One Eye

Signs That May Accompany Blurry Vision in One Eye

Blurry vision in one eye often occurs alongside other symptoms, which can provide valuable insight into its cause. Paying attention to these accompanying signs can help you determine if immediate medical care is necessary. Symptoms can range from mild to severe and may develop gradually or appear suddenly. If you experience any of the following symptoms along with blurry vision, it’s important to schedule an evaluation with an eye doctor.

• Headaches: Persistent or severe headaches may be associated with migraines, eye strain, or other vision-related problems. 

• Eye Pain: Sharp or consistent pain in the affected eye could signal inflammation, infection, or an injury. 

• Light Sensitivity: Sensitivity to light, or photophobia, is commonly linked to conditions such as corneal abrasions, dry eye, or infections. 

• Floaters or Flashes of Light: A sudden increase in floaters or flashes of light might indicate a serious condition like retinal detachment. 

• Tearing or Discharge: Watery or sticky discharge can be a sign of infections like conjunctivitis or dry eye syndrome. 

• Redness: Redness in the eye often accompanies irritation, inflammation, or conditions like uveitis or conjunctivitis. 

• Halos or Distorted Vision: Seeing halos around lights or experiencing distortion may be a sign of cataracts or corneal issues. 

Urgent Conditions That Require Immediate Attention from an Eye Doctor

Blurry vision in one eye isn’t always a major concern, but certain situations call for prompt medical care. Being able to identify these emergencies is crucial for protecting your vision and ensuring timely treatment. Below are some serious conditions linked to blurry vision in one eye that require urgent attention.

Corneal Abrasion and Scratch

The cornea is the clear, dome-shaped structure at the front of the eye that helps focus light and shields your eye from dirt and debris. Its exposed position makes it vulnerable to scratches, which can occur during everyday activities like applying contact lenses or rubbing your eyes.

A scratched cornea, or corneal abrasion, often causes significant discomfort, sensitivity to light, and blurry vision. This condition can result from contact lens overuse, foreign particles in the eye, accidental injuries, or dry eye syndrome. If you suspect a corneal abrasion, visit your eye doctor immediately. Left untreated, these scratches can lead to infections or corneal ulcers, which could compromise your vision. 

Retinal Detachment

The retina is a thin layer of light-sensitive tissue at the back of the eye that converts light into visual signals. Retinal detachment occurs when the retina separates from its position, cutting off its blood supply and impairing its function. This condition can develop gradually or happen suddenly, depending on the cause.

Early signs of retinal detachment often include flashes of light, an increase in floaters, or shadows in your field of vision. In some cases, it may occur without warning symptoms. Those with a higher risk include:

• High levels of trauma 

• Ocular degenerative conditions 

• Uncontrolled diabetes 

• Chronic inflammation 

• Recent retinal surgery 

• Family history of this condition 

If you suspect retinal detachment, seek immediate medical care. Delays in treatment can result in irreversible damage and permanent vision loss.

Angle-Closure Glaucoma

Angle-closure glaucoma is a rare but critical condition that develops when the eye’s drainage system becomes suddenly blocked, leading to a rapid increase in intraocular pressure. This pressure buildup can quickly damage the optic nerve, posing a serious threat to vision.

Symptoms of angle-closure glaucoma often include intense pain in the eye or head, blurry vision, nausea, and halos around lights. Unlike open-angle glaucoma, which progresses slowly, angle-closure glaucoma can cause severe vision loss within hours if untreated. If you experience these symptoms, seek emergency care immediately.

Stroke

Blurry vision in one or both eyes can sometimes signal a stroke, a medical emergency where blood flow to the brain is interrupted. This lack of oxygen can affect various functions, including vision, and may occur alongside other physical and cognitive symptoms. In the U.S., someone experiences a stroke every 40 seconds.

If you or someone else experiences blurry vision combined with any of the following, call 911 immediately: 

• Weakness or numbness on one side of the body 

• Confusion 

• Trouble walking 

• Blurry vision 

Non-Emergency Causes of Blurry Vision

Blurry vision doesn’t always indicate a medical emergency. It can stem from a variety of factors, including natural changes in your eyesight or manageable conditions. While some cases are temporary or easily addressed, others may require an evaluation by an eye care professional to ensure proper treatment.

Age-Related Vision Changes

As you age, it’s normal to experience gradual changes in vision due to refractive errors like nearsightedness, farsightedness, or astigmatism. These conditions affect how light is focused on the retina, often leading to blurry vision that can be corrected with glasses, contact lenses, or other treatments.

• Astigmatism is caused by an irregular shape in the cornea or lens, which prevents light from focusing evenly on the retina. This results in blurred or distorted vision at various distances and may also cause eye strain or headaches. 

• Nearsightedness (myopia) occurs when the eyeball is too long or the cornea has excessive curvature, making it difficult to see objects at a distance. This common condition is often noticeable in childhood or adolescence. 

• Farsightedness (hyperopia) is the opposite, causing difficulty seeing nearby objects while distant vision remains clear. It’s caused by a shorter eyeball or a flatter cornea, which causes light to focus behind the retina. 

If blurry vision is interfering with your daily activities, an eye exam at eyecarecenter can help. Your doctor will assess your vision and provide a prescription for corrective lenses or other treatments to restore clarity.

Dry Eye Syndrome

Dry eye syndrome affects nearly 16 million people in the United States, causing discomfort and, in some cases, blurry vision. This condition occurs when the eyes don’t produce enough tears or when tears evaporate too quickly, leaving the eyes dry and irritated.

Dry eye can result from several factors, including aging, extended screen use, certain medications, and environmental conditions like wind or dry air. Over-the-counter artificial tears can offer temporary relief, but they may not address the root cause of the problem. Visiting an eye doctor at eyecarecenter ensures you receive a personalized treatment plan that targets the underlying causes of your dry eye, helping you achieve long-term comfort and clearer vision.

Vision Changes Caused by Medications

Certain medications can cause blurry vision as a side effect. Common drugs linked to vision issues include antihistamines, corticosteroids, antimalarials, and antipsychotics.

People with pre-existing conditions like glaucoma or diabetes may be more prone to experiencing vision-related side effects from medications. If you suspect your medication is causing blurry vision, consult your eye doctor or pharmacist for advice. They can assess your situation, suggest alternative medications, or adjust your treatment plan. Avoid stopping any prescribed medication without professional guidance to ensure your overall health remains protected.

Macular Degeneration

Macular degeneration is a condition that affects the central part of your vision and becomes more prevalent with age. It affects approximately 11 million people in the United States and is classified into two types: dry and wet macular degeneration.

• Dry Macular Degeneration: This form occurs when the light-sensitive cells in the macula break down over time. It is the more common type and often leads to blurry central vision and difficulty seeing in dim light. 

• Wet Macular Degeneration: In 10% to 15% of cases, dry macular degeneration progresses to the wet form, characterized by abnormal blood vessels leaking fluid or blood into the retina. This causes rapid vision loss, often beginning with blurry or distorted central vision in one eye.
