Blurred Vision - Causes, Conditions & When to See a Doctor
Blurred vision is a loss of sharpness in eyesight, making objects appear out of focus and hazy. It can affect one or both eyes.
Overview
Blurred vision is one of the most common eye complaints. While it is often due to refractive errors (nearsightedness, farsightedness, astigmatism), it can also be a symptom of serious conditions like diabetes, glaucoma, or stroke.
Conditions That Cause Blurred Vision
Blurred Vision can be associated with several medical conditions. Understanding the underlying cause is important for proper treatment.
Conjunctivitis
Conjunctivitis (pink eye) is an inflammation or infection of the transparent membrane (conjunctiva) that lines the eyelid and covers the white part of the eyeball.
Migraine with Aura
Common causeMigraine with aura is a type of migraine preceded or accompanied by sensory disturbances such as flashes of light, blind spots, tingling, or speech changes.
Stroke
A stroke occurs when blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Brain cells begin to die within minutes.
When to See a Doctor for Blurred Vision
See an eye specialist for any persistent change in vision. Seek emergency care for sudden blurred vision, especially with eye pain, headache, double vision, vision loss, flashing lights, or floaters — these may indicate retinal detachment or stroke.
