Have you ever seen a temporary black spot in your vision? How about jagged white lines? Something that looks like heat waves shimmering in your peripheral vision?
If you have, you may have been experiencing what is known as an ocular migraine. Ocular migraines occur when blood vessels spasm in the visual center of the brain (the occipital lobe) or the retina.
Although the symptoms can cause a great deal of anxiety, especially on the first occurrence, ocular migraines rarely cause any long-term problems and almost never require treatment as long as they are not accompanied by significant headaches.
