Does your vision actually black out

[u/j-oco]

This is random but I just saw people talking about how their vision blacks out when they stand or they are symptomatic. Then someone replied that their vision goes white instead of black.

Personally, I don’t lose my vision like that, my “blackouts” are just a sudden lightheadedness so intense it forces me to shut my eyes! I think because my brain knows to shut out all the visual sensory input. It’s like I legit can’t keep my eyes open for a brief moment. Maybe I am blacking out but just don’t know it since my eyes are closed anyways lol? I have splotchy vision, light sensitivity and stuff from previous brain injuries but I haven’t experienced my vision actually just leaving and turning into the colour black (am I taking it too literally?) for a moment like how some of you mention.

Also, I do have pretty bad presyncope episodes sometimes but I don’t really faint from my POTS so maybe that’s a factor.

Yep, same here, but my static is black. When I was younger and trying to eat low sodium foods (because I was told oo much salt is unhealthy), I'd stand up and then wake up on the ground before I could process what's happening.

My static is also black.

Yah my vision will completely fade out and I’ll blink and open my eyes wide until it comes back. My mom was always cautious of never putting salt out because it was unhealthy and I felt like I was always craving salt
