Every so often my vision goes black for about 1 second, and it feels like my eyes are srambling around searching for a focal point. Then (after about 1 second), my vision returns and everything is normal again. This usually happens when I am doing close work: reading, taking notes, intense crafts, etc. This began happening about 5-6 years ago, though it only happened maybe once every few months. Now it can happen as much as 3-6 times a day, though it mostly happens much less... Maybe once every few days, depending on how much close work I m doing. I m 23, female, no drugs, drinking, or smoking, healthy lifestyle (mostly vegan), mother of 2.
