Common migraine may cause only a headache felt on both sides of the head.

With an ocular migraine, symptoms can include flashes of light that look like jagged lines or “heat waves” in both eyes, often lasting 10 to 20 minutes. There may be vision loss in one eye only, involving the entire field or only the upper or lower section. There may or may not be a headache following these ocular symptoms.

Rare migraine symptoms include double vision, change in lid position (lid droop), or change in pupil size (both smaller and larger). In very rare cases, the visual problems associated with migraine may not entirely disappear. This may be due to a stroke associated with migraine.
