Blurred, darkened and double vision are possible symptoms of a stroke, according to Mayo Clinic. The vision disturbances may affect both eyes or only one eye. These vision symptoms may occur with other stroke symptoms such as numbness, paralysis, headache, walking difficulty or confusion, states Mayo Clinic.
Vision disturbances associated with a stroke don't always clear up immediately. Stroke victims often have continued vision problems including vision loss and visual perception problems, says the National Stroke Association. Vision loss may occur in spots, cause tunnel vision or affect only part of the visual field, such as the left field of vision. Double vision, the inability to recognize objects, hallucinations and color detection issues are potential perception issues.
