I've been having these strange vision problems since 2016. Doctors have checked my brain and my eyes but hasn't found anything. It started with the typical ocular migraine symptoms with zigzag flashing lines. but the last year, vision just becomes brighter and unfocused. It only last a couple of minutes and it comes without a warning. It's only my left eye thats affected. It happens twice a month. Does anyone recognize this? I've tried to make an image in photoshop of what it looks like. Sometimes the lights shimmer. https://patient.azureedge.net/forums/images/upload/1006366-636783392141012998.jpg
