@guizzy hmm, have had migraines before, but it always was with a lot of pain so didn't question it so much. this is no pain at all so got kinda surprised, if it's really the same thing
@shmibshttps://www.healthline.com/health/causes-of-ocular-migraines#_noHeaderPrefixedContent>During an ocular migraine, or migraine with aura, you may see flashing or shimmering lights, zigzagging lines, or stars. Some people describe psychedelic images. It may also cause blind spots in your field of vision. Of people who report having migraines, one out of every five experiences this aura.>Ocular migraines can interfere with your ability to perform tasks like reading, writing, or driving. Symptoms are temporary and an ocular migraine is not considered a serious condition.
@shmibs Mine had no pain too, it can be with or without pain. I was legit scared for a moment when it started, I feared I was going blind suddenly. It didn't feel like my eye was unable to see light, just that a growing portion of my vision was shimmering and hard to discern anything. It went away on its own.
