I get those occasionally. I went to an eye doctor and he called them "eye migraines". Haven't had them for awhile, but when I do they remind me of a Star Trek episode where Captain Kirk is being tortured by jagged bright images on both sides of him.
You're welcome. Hope it gets resolved soon.
Anything out of the ordinary should cause some concern and discussed with a doctor in length. I had friend who saw things like that, had reoccurring headaches, ignored them for years until it became unbearable. They found the cause, an inoperable brain tumor.
