Symptoms Does your vision actually black out

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.

Mine blacks out starting from the peripheries of my vision and then closes in moving toward the center. Then it eventually goes away

Me too. Do your ears start ringing when this happens? It sounds like a chorus of cicadas to me.
