Please explain what it means if i have blurry vision in one eye?

Many causes: Is this of recent onset or has the vision been blurry in that eye for a long time? Is there a history of eye disease? Or trauma? If there is no obvious cause, then check with your ophthalmologist to see if there is a diagnosis and treatment.

Blurry vision : Blurry vision means vision is not clear: letters on 20/20 eye chart are not clear. Could be due to: need glasses, and astigmatism; dry eye/tear film issue; cataract/lens changes; retinal, optic nerve, or brain issue. EyeMD can determine cause. Most common due to need for glasses or tear film issue.
