Blurred Vision
Key Points
Refractive error is the most common cause of blurred vision. If refractive error is the problem, corrective lenses or surgery (particularly if cataracts are the cause of the change in refractive error) can usually correct the blurriness. Doctors check visual acuity and determine whether glasses or a pinhole device corrects the problem, and if it does not, they dilate the eye with drops and carefully examine the retina. People with warning signs should see a doctor as soon as possible. Because glaucoma is common, intraocular pressure is usually measured.
