Blurry Vision: Common Causes and When to See an Eye Doctor
By Dr. Belkis Perez, OD · Published
Blurry vision is most often caused by refractive errors such as nearsightedness, farsightedness, astigmatism, or presbyopia, but it can also relate to dry eye or other conditions. Sudden blurry vision is an emergency.
Common causes
Refractive errors, presbyopia after 40, dry eye, cataracts, and diabetes-related changes are frequent causes evaluated in a comprehensive exam.
Warning signs
Sudden vision loss, flashes, a curtain over your vision, severe pain, or blurriness after an injury require immediate emergency care.
