See Doctor ASAP!: A blackout of vision is a worrisome symptom and you should see your medical doctor and your eye doctor right away.

See your doctor asap!
See your doctor: You could be anemic or others -- your doctor needs to sort it out.
Blood filling veins: When we stand up rapidly, gravity pulls the blood down towards our feet. The veins in our legs swell to accomadate this. This is like some one suddenly removed a pint or more of blood. Our heart rate increass and our blood pressure falls. This can make people feel faint or dizzy. When you take blood press medicines it can make the dizziness more noticalbe.
Low flow to brain...: The most common cause of fainting when rising to a standing position is decreased blood flow to the brain. This can result from either low blood pressure to begin with, or other conditions that cause the flow to the brain to decrease. This syndrome is relatively common. It can be helped by ensuring adequate salt and fluid intake. If that does not help, a tilt table test is indicated.
Dehydration: Drink some water before sleep if your can -- or sport drinks.
Blackout of vision: Main causes of sudden black out: dehydration/illness, blood pressure drop, blood sugar drop (pre-diabetes/diabetes), vasovagal reaction, blood flow issue in brain (from dehydration, sugar level change, tumor of some type, intracranial pressure increase.)
