In brief: Aura

Many people suffer a variety of different visual disturbances prior to developing a migraine.
This is known as an aura. The disturbances may vary from seeing black wiping out part of your visual field, to seeing wavy lines or spots before your eyes, that may even persist once your eyes are closed. For more information on migraines see: http://understandingmigraine.blogspot.com/

In brief: Classical migraine

The visual distortions are auras associated with the onset of the event and are due to a chemical electrical alteration of neuronal function called a spreading depression which causes malfunction in the occipital lobe initially resulting in the visual scotoma or loss of vision.
