You may not need to take migraine medication if you are experiencing a visual migraine attack. There are many names for visual migraines (migraine aura with no headaches, typical aura without headaches or eye migraine), but the mere mention of “migraine” does not necessarily mean you are having a splitting headache. This is the migraine without the headache.
Visual migraine
Visual migraine sufferers often forget they have it. It usually affects one eye. It can cause blurred vision, temporary blindness, blurred vision, zigzag lines, and flickering lights. This is similar to a bar or rave light that can interfere with your vision. Although it can cause headaches, it is very rare. Other symptoms include nausea, vomiting and fatigue, as well as heightened sensitivity to light or sounds.

There are common migraine triggers, which are often the same ones that cause classic migraines.
