Possible Causes of Visual Blackout

Of course, within a moment, when blood pressure returns to normal, you regain vision and blood flows to the head.

It is possible that there is a tear at the retina that can cause vision loss for brief moments, because, of course, the eye might not be functioning fully if this has occurred. If a tear happens in the retina, fluid gets behind the retina and lifts it off the wall of the eye, causing a perceived darkness of vision. pinterest-pin-it
