Indistinct or fuzzy visual images. Blurred vision, which should not be confused with double vision (diplopia), can occur in 1 eye or both, for episodes of varying lengths of time, and can develop gradually or suddenly. The usual cause of longstanding blurred vision is a refractive error such as astigmatism (unequal curvature of the front of the eye), hypermetropia (longsightedness), or myopia (shortsightedness), all of which can be corrected by glasses or contact lenses. After the age of 40, presbyopia (reduced ability to focus on near objects) becomes more common. Vision may also be impaired or blurred as a result of damage, disease, or abnormalities of parts of the eye or its connections to the brain. The most common causes of blurred vision as a result of disease are cataract and retinopathy.
