What Causes Blackouts In Vision?

For 2 years I have been having an issue. Occasionally I will be in class and will blackout . I will continue writing, but my writing becomes illegible, and sometimes just says random words. I will have no idea when it s about to happen or when it s happening. I ll have no idea what the teacher said, but I will look back at my notes and realize it s happened again. It s not like I m falling asleep in class or anything, because i keep functioning and my eyes are still open. Do you have any idea what this could be?

Hello
Welcome to health care magic

I reviewed your history.
It seems from the history that you are having episodes of sudden blackouts of vision.
These symptoms indicates transient ischemic attack.
The common causes that needs to be ruled out are vascular causes.
The other common causes that can be considered are hypotension, anemia,...
Hence I advice you to consult your doctor for evaluation to find out the underlying cause and treatment accordingly.

Hope this is helpful to you.

Thank
