Why are my eyes blurry all of a sudden?

Sudden blurry vision can be caused by a variety of factors, some of which may be temporary and others more serious. Temporary causes can include eye strain from excessive screen time, prolonged reading, or exposure to bright light. Dry eyes, which may result from environmental factors or inadequate tear production, can also lead to temporary blurriness. Allergies or conjunctivitis may cause sudden blurry vision accompanied by itching, redness, or discharge. However, more serious conditions can also cause sudden blurriness, such as retinal detachment, which may be accompanied by floaters and flashes of light, or optic neuritis, which can be associated with pain and vision loss. It is essential to seek medical attention from our eye care professional if you experience sudden blurry vision, especially if it persists or worsens, as early detection and intervention are crucial for preventing potential vision loss and addressing any underlying health issues. Call us at (360) 491-2121 to speak with our team for more specific information.

Causes of Blurry Vision in One Eye

There are several potential causes of blurry vision in one eye. Some of these include:

Refractive errors: Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are common vision problems that can cause blurry vision in one or both eyes. Learn more about myopia here.

Dry eyes: Insufficient tear production or poor-quality tears can lead to dry eyes, which may cause blurriness, discomfort, and even pain. Learn more about dry eyes here.

Cataracts: A cataract is a clouding of the eye's lens that can cause vision to become blurry, hazy, or less colorful. Cataracts are most common in older adults. Learn more about cataracts here.

Macular degeneration: Macular degeneration is an eye disease that affects the macula, the central part of the retina responsible for sharp central vision. It can cause blurry or distorted vision in one or both eyes. Learn more about macular degeneration here.

Optic neuritis: Inflammation of the optic nerve can cause blurry vision, usually in one eye, along with eye pain and vision loss. Optic neuritis is often linked to autoimmune diseases like multiple sclerosis

Retinal detachment: A retinal detachment occurs when the retina separates from the back of the eye. This serious condition can cause sudden blurry vision, floaters, or flashes of light, and requires immediate medical attention.

Diagnosing Blurry Vision in One Eye

If you experience blurry vision in one eye, it's essential to visit our eye doctor for a comprehensive eye exam. The exam may include:

Visual acuity test: This test measures the sharpness of your vision using an eye chart with letters or symbols.

Refraction assessment: Your eye doctor will use various lenses to determine the most appropriate prescription to correct your vision.

Slit-lamp examination: A slit-lamp is a specialized microscope that allows your eye doctor to examine the structures of your eye in detail, including the cornea, iris, and lens.

Pupil dilation: We may dilate your pupils using special eye drops. This helps them get a better view of the retina and other internal structures of the eye.

Retinal examination: A thorough examination of the retina, macula, and optic nerve is essential to identify any underlying conditions causing blurry vision.

Eye pressure test: Measuring the pressure inside your eyes (intraocular pressure) can help detect glaucoma, which can cause vision problems.

Blood tests: In some cases, blood tests may be necessary to check for underlying health conditions, such as diabetes, that can affect your vision.

Treatment Options for Blurry Vision in One Eye

Treatment for blurry vision in one eye will depend on the underlying cause. Some common treatment options include:

Glasses or contact lenses: Refractive errors can be corrected with prescription glasses or contact lenses, which help focus light correctly on the retina.

Artificial tears: For dry eyes, over-the-counter artificial tears can provide relief and improve vision.

Cataract surgery: Cataract surgery involves removing the clouded lens and replacing it with an artificial one to restore clear vision.

Age-related macular degeneration treatment: Treatment options for macular degeneration include injections, laser therapy, and nutritional supplements. Early detection is crucial for preserving vision.

Optic neuritis treatment: Treatment for optic neuritis typically involves corticosteroids to reduce inflammation and improve vision.

Retinal detachment surgery: Retinal detachment requires prompt surgical intervention to reattach the retina and preserve vision.


According to the World Health Organization (WHO), approximately 2.2 billion people worldwide have a vision impairment or blindness, with refractive errors being the leading cause.

Prevent Blindness reports that cataracts are the leading cause of blindness globally, affecting over 24 million Americans aged 40 and older.

The American Academy of Ophthalmology states that age-related macular degeneration is the leading cause of vision loss in people aged 50 and older in the United States.

Common Questions

Experiencing blurry vision in one eye can be concerning, and while it may be caused by a temporary or benign condition, it is essential to take it seriously. In some cases, blurry vision may indicate a more serious underlying issue that requires prompt attention and treatment to prevent potential vision loss or other complications. If you experience sudden or persistent blurry vision in one eye, it is important to consult our optometrist for a thorough evaluation. They will be able to determine the cause of the blurriness and recommend appropriate treatment or management strategies.
Fixing blurry vision in one eye requires identifying and addressing the underlying cause, which can be determined through a consultation with our eye care professional. If the blurriness is due to refractive errors such as nearsightedness, farsightedness, or astigmatism, prescription eyeglasses or contact lenses can help restore clear vision. For dry eyes, over-the-counter artificial tears can provide relief while more advanced treatments can address the underlying cause of your dry eye. In cases of infection or inflammation, like conjunctivitis or optic neuritis, prescription medications or steroid eye drops may be necessary. If cataracts are the cause, cataract surgery can replace the clouded lens with an artificial one to restore clarity. Retinal detachment may require surgical intervention to reattach the retina and preserve vision. For macular degeneration, various management strategies such as medication injections, laser therapy, or nutritional supplements can help slow progression and maintain vision. It is crucial to consult our optometrist for the most appropriate course of action based on your specific situation. Early intervention is key to preserving vision and maintaining overall eye health.
There is no direct evidence to suggest that low vitamin D levels cause blurred vision. However, vitamin D deficiency has been associated with an increased risk of developing certain eye conditions that could potentially lead to vision problems. For example, a deficiency in vitamin D has been linked to a higher risk of age-related macular degeneration (AMD), which can cause blurriness and distorted vision. Additionally, vitamin D deficiency may contribute to the development of dry eye syndrome, where inadequate tear production or poor tear quality can lead to discomfort and blurry vision. It is important to maintain a balanced diet with adequate vitamin D intake to support overall health and potentially reduce the risk of these eye conditions. If you experience blurred vision or any other vision changes, it is essential to consult our eye doctor for a thorough evaluation and appropriate treatment recommendations.
Blurred vision in your left eye can be attributed to various factors, ranging from mild to more serious conditions. Temporary blurriness may be caused by factors like eye strain, dry eyes, or allergies. Refractive errors, such as nearsightedness, farsightedness, or astigmatism, can also lead to blurry vision in one or both eyes and may be corrected with prescription eyeglasses or contact lenses. More serious conditions, like cataracts, retinal detachment, or macular degeneration, can cause vision changes and may require prompt medical attention. Inflammation or infection, such as conjunctivitis or optic neuritis, can also result in blurry vision. If you are experiencing persistent or sudden blurred vision in your left eye, it is crucial to consult our eye care professional for a proper evaluation and appropriate treatment recommendations. Early detection and intervention can help protect your vision and overall eye health.
Lack of sleep can indeed cause blurry vision, as well as other visual disturbances. Insufficient sleep can lead to eye strain, dryness, and discomfort, all of which can contribute to temporary blurriness. When you are sleep-deprived, your eyes may not produce enough tears to keep them well-lubricated, leading to dry eye syndrome and subsequent blurry vision. Additionally, fatigue can cause the muscles around your eyes to weaken, making it difficult for your eyes to focus properly. This lack of focus can result in temporary blurriness or even double vision. While these visual disturbances are generally temporary and resolve once you get adequate rest, it is important to prioritize sleep and maintain a healthy sleep schedule for overall eye health and well-being. If you continue to experience blurry vision despite getting sufficient sleep, it is crucial to consult our optometrist for a thorough evaluation and appropriate treatment recommendations.
Determining whether your blurred vision is serious requires paying attention to accompanying symptoms and the duration of the blurriness. If your blurred vision is sudden, persistent, or accompanied by other symptoms such as eye pain, headache, floaters, flashes of light, or vision loss, it may be indicative of a more serious issue that requires prompt medical attention. Conditions like retinal detachment, optic neuritis, or angle-closure glaucoma can cause sudden vision changes and may lead to permanent vision loss if left untreated. However, if your blurred vision is mild and transient, it could be related to temporary factors like eye strain, dry eyes, or uncorrected refractive errors. In any case, if you experience blurred vision that persists or worsens, it is essential to consult our eye care professional for a thorough evaluation and appropriate treatment recommendations. Early detection and intervention can help protect your vision and overall eye health.

Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.

Anna P.

I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.

June S.

Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.

Christine R.

Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

Lars Wulff

Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.

Justin E.

The staff is friendly. The Doc is very knowledgeable. The office is family friendly and everyone is so patient with the little ones.
