My teenage daughter started having auras about 6 months ago, they last a couple of seconds then eyes return to normal, classic auras, zig zags and sparkles. No headache or any other symptoms. They were happening a few times a week but now a few times a day. Eyes have been checked and blood and GP keeping an eye on it. Optician said it is optical migraines. Her dad and I have both had migraines before. Anyone else experienced this? GP thought hormonal because of age.
