![]() Some people explain a “kaleidoscope” effect, with pieces of the vision being missing. Some individuals get different variations of this phenomenon, with the central vision being involved, or with the visual result just like “heat rising off of a car”. The visual phenomenon would also be perceived in the nasal field of view of the other eye. It is normally primarily viewed as happening in the eye where is inhabits the temporal (outside) field of view. Given that migraine originates in the brain, the visual result typically involves the very same side of vision in each eye, although it may seem more popular in one eye or the other. In truth, it is normally a harmless phenomenon (with one exception noted listed below), although many individuals subsequently get the migraine headache. When it is big, this crescent shaped blind spot containing this brilliantly flashing light can be difficult to ignore, and some people fear that they are having a stroke. This increases the size of, and relocates to one side or the other of the vision, over the 5 to 30 minute period. Classically, a little blind spot appears in the main vision with a sparkling, zig-zag flicker light inside of it (“scintillating scotoma”). This visual aura can be extremely dramatic. Some people, nevertheless, experience the aura however do not have a headache. Migraine headaches may be preceded by a visual “aura”, lasting for 5 to 30 minutes (most commonly around 15 minutes), and then proceeding to the headache. Once the flashing lights begin you can prevent a fullblown migraine by taking painkillers, drinking water, upping your blood sugar with food and laying down in a quite, dark space. These flashing lights look like broken glass or water running down over gleaming lights. Flashing lights that last for 15 to 30 minutes are often symptomatic of ocular migraines, which are headaches that also cause colored lights usually in both eyes. Your brain interprets this as different colors.įlashing lights can also be an early warning for migraines. This is caused when the photosensitive cells on the retina are briefly bleached and take a few seconds to adjust. Everybody will see colored spots if we looking at a brilliant item for long enough and after that at a white wall. Kaleidoscope vision could be a caution of a migraine. ![]()
