Cause of white flashes in peripheral vision in just one eye? they aren't happening anymore, but did earlier today. i don't get migraines. had no pain.

Flashing: Seeing Flashing lights: due to either traction of the vitreous gel in the eye on the retina (which is an extension of the brain & makes the brain sense flashes); if you have new floaters or "see" a curtain coming over your vision, see eyeMD asap. Ophthalmic migraines are visual symptoms (like seeing flashing lights) without a headache. See your eyeMD to be sure it is not a new retinal hole/tear.
