I am sorry to hear that and it's quite normal to get red eyes with migraines. Migraine is one of the most common complaints in medicine, and it is more common in people who had migraine when they were younger or who have a family history of migraine. They are stemmed from spasms of blood vessels in the vision part of your brain, which can increase your blood pressure. In that way, it will also affect your eyes, leading to high eye pressure. At this moment, red eyes can occur because of high eye pressure. Thus if you want to get rid of this situation, I suggest you should take a thorough eye examination to make sure the diagnosis first. If the problem occurs more than once, you had better take aspirin and take a nap. Vitamin C is also helpful. But if the symptom still exist, you'd better consult an doctor. Hope these can be helped.
