Visual migraines
Visual migraines
There are three visual disturbances that occur in visual migraines, and each of these disturbances is triggered by separate stimuli. This kind of migraine is triggered by tiredness and stress, and this is often followed by your normal migraine headache, accompanied with vomiting. Good to know is that the visuals come after the headaches. If it was the other way around, you would probably experience the vomiting and the visuals at the same time. There is a central irregular point in the eye that becomes nothingness at the start of the migraine, and this might grow and last for around 30 minutes. This is easy for one to get around because you will still be able to see things around the edges of that nothingness. The border of this nothingness has unpredictable sides. It takes time before the nothingness fades and you are able to see properly. A great way of representing this visual migraine is in an oil painting. Superimpose an irregular polygon of a cold color onto the center of the painting. Now portray that polygon to grow in size and it will make an uninteresting painting. Second type, this time the expanding polygon has a major difference. The borders of it appear as bands of pulsating and scintillating color. The colors flow through and around the bands in waves, but irregular ones. There is no central part in the vision that is nothingness, but there is a distorted and broken image of the things you are looking at. If you are one that stares too long at table information on a monitor, visual migraines are usually triggered. If you can get around looking at spreadsheets on a computer, do so. Once you are infected, the migraine usually lasts for an hour. It is better to describe this type of migraine in a water painting. The visual content is high in degree that when trying to express it in a painting it’s difficult. The straight lines in the bands can be portrayed as bright colors scattered with white. Third type, this visual migraine is different. Spreadsheets on a computer can trigger this, but for other reasons. This migraine creates odd space in one’s vision that is not there. This is disturbing and can lead to unbalance. In a portrait, it is better to describe this as a 3D portrait, which can be extremely hard to produce when looking a flat image.
