When Is Blurry Vision a Medical Emergency?

Blurry vision is one of the most common eye complaints, and in many cases, it may simply mean you need an updated glasses or contact lens prescription. However, sudden or severe changes in vision can sometimes signal a more serious underlying condition that requires urgent medical attention. Knowing when to seek help can make a significant difference in protecting your eyesight.
 

Non-Emergency Causes of Blurry Vision

Not all blurry vision is dangerous. Some common, non-urgent causes include:

• Refractive errors like nearsightedness, farsightedness, or astigmatism
• Digital eye strain from prolonged screen time
• Dry eyes that temporarily affect clarity
• Outdated prescription lenses

These situations can often be addressed by scheduling a routine eye exam.
 

Warning Signs That Blurry Vision May Be an Emergency

You should seek immediate medical care if blurry vision occurs with any of the following:

• Sudden vision loss in one or both eyes - This can indicate a retinal detachment, stroke, or other urgent issue.
• Flashes of light or a shower of floaters - May suggest retinal tears or detachment.
• Severe eye pain or redness - Could be linked to conditions such as acute glaucoma or serious eye infections.
• Double vision - Especially if it comes on suddenly, as it may point to neurological problems.

Medical Conditions That Require Prompt Attention

Blurry vision may be a symptom of more serious health issues, including:

• Retinal detachment - A medical emergency that can lead to permanent vision loss without urgent treatment.
• Stroke or transient ischemic attack (TIA) - Sudden vision changes may accompany other neurological symptoms.
• Acute angle-closure glaucoma - Rapid eye pressure increase that can cause pain, halos around lights, and sudden vision loss.
• Diabetic eye disease - Sudden blurriness in people with diabetes may indicate bleeding or swelling in the retina.
