The problem is not in the eyes but in the brain. Standing up suddenly can cause low blood pressure in the brain which can cause parts of it to selectively shut-down momentarily. To avoid this problem get yourself a little excited before standing up: hyperventilate (slightly), pump your muscles, stretch your legs, think of what George Bush did to the economy.

What does it mean when you stand up fast and your vision goes black?
It means that your blood pressure is too low, above the level of your heart. This is called "orthostatic hypotension". The way to compensate is to sit up first, for 15-20 seconds and then stand up slowly. This problem is not unusual, as we age.

Why is when sometimes you stand up everything goes black?
What you were experiencing, in doctor speak, is orthostatic hypotension, a sudden drop in blood pressure.Normally, blood vessels constrict to maintain blood pressure and compensate for changes in position, but in some cases the blood vessels don't compensate and, when you stand up, the blood doesn't go to the brain. Basically, the reflexes of the body don't catch up with the blood vessels.Read more: http://wiki.answers.com/What_does_it_mean_when_you_stand_up_and_stretch_and_everything_goes_black_almost_like_you_are_momentarily_blind_and_you_feel_dizzy_so_you_have_to_hold_onto_a_chair_to_keep_your_balance#ixzz1LpwAP9PG
