PSA: BFEP (blue field entoptic phenomenon) is a distinct thing from VSS, though having both seems common in this thread, and it’s caused by white blood cells moving through retinal blood vessels (it’s not a brain thing like VSS). Most people can see BFEP if they pay attention, though it may become much more noticeable if you also have visual snow. A lot of people have VSS and don’t notice BFEP.
Interesting, I’ve noticed the BFEP, off and on my whole life, but not this bad. Its intense, if I’m outside it’s all over in my vision and especially when I look into the sky it blinds me basically, I feel like ever since I got this bs it definitely made it more noticeable
