About the Symptom
Blurry vision is a symptom in which someone is unable to visually distinguish details or sharp contours of their surroundings.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Photophobia
- Eye pain
- Visual field defect
- double vision
Possible Causes
Generally, Blurred vision can be related to:
- Neuromyelitis Optica (NMO)
Neuromyelitis optica (NMO) is a rare condition in which the immune system damages the spinal cord and the optic nerves.
- Cataracts
Degeneration of the lens inside the eye causes it to become opaque. As a result, lights appear glaring and vision becomes blurred. In older adults, cataracts are usually caused by aging. In children, however, they may be due to genetic conditions, drugs, or viral infections while in the womb.
- Macular Edema
Macular edema is the accumulation of fluid in the macula, the part of your retina responsible for central vision. It occurs when fluid leads to swelling in the macula, causing blurred vision and vision loss in severe cases. Common causes of macular edema include blockages in retinal arteries or veins and diabetes.
- Tolosa Hunt Syndrome
- Diabetic Macular Edema (DME)
- Migraine
- Subcortical Hemorrhage
- Age-Related Macular Degeneration
- Sarcoidosis (Including Erythema Nodosum-Like Eruption)
Related Serious Diseases
Sometimes, Blurred vision may be related to these serious diseases:
- Acute Glaucoma Attack
A condition caused by high pressures in the eyeball, more common in people with farsightedness. Persons of Black, Asian, or Hispanic descent are at higher risk. The high pressures can cut off blood flow to the eye. Prompt medical attention is needed to prevent permanent blindness.
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Is your vision blurry?
- When did you first notice your vision problems?
- Which of the following best describes how your vision problems appeared?
- How is your vision problem now?
- Are you currently experiencing vision loss in one eye?

FAQs
Q.
What Are the Possible Causes of Sudden Blurry Vision in Both Eyes?
A.
Sudden blurry vision in both eyes can happen because of different health problems like a mini-stroke, high eye pressure, inflammation of eye nerves, or issues with the blood vessels in the eyes.

Q.
Why Am I Having Sudden Blurred Vision and Dizziness When Standing Up?
A.
When you stand up and suddenly feel dizzy with blurry vision, your blood pressure might drop quickly, making it hard for your brain and eyes to get enough blood. This is often known as orthostatic hypotension or orthostatic syncope.

Q.
What Are the Possible Causes of Blurred Vision In One Eye?

Blurred vision in one eye can happen from many issues like an eye infection, a cataract, or problems with the back of the eye such as those seen in macular degeneration.

Can Low Blood Pressure Cause Blurred Vision?
