Yes, migraines will affect your vision. And it may lead to visual migraines, which are similar to the aura people with migraine headaches experience, but there is no headache followed. Visual migraines are more common in people who had migraine headaches when they were younger or who have a family history of migraine headaches. So if you want to get rid of this situation, I suggest you should follow these tips. First, you should take a thorough eye examination to make sure the diagnosis. If the problem occurs more than once, you can look for triggers that might bring them on and then try to avoid them. It could be stress, fatigue, bright lights, hormonal changes, red wine or certain foods. Anyway, just treat it as soon as possible.
