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.
cause your blood pressure goes down
hold the stand by button and the home menu button until the screen goes black and then starts back up again.
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.
Gravity.
I have the same problem and I can say it isn't normal. Before I can diagnose it, when you stand up and everything goes blurry do you see yellow and black patches?
When you stand up quickly, blood flow to your brain may temporarily decrease, causing a decrease in oxygen levels. This can result in a brief episode of temporary low blood pressure, known as orthostatic hypotension, which may cause everything to go black for a moment until your body adjusts and blood flow to the brain normalizes.
In the movie Billy Black, played by Gil Birmingham, is confined to a wheelchair and cannot stand up. Billy Black is Jacobs Dad. Gil Birmingham has no mobility problems and is a dynamite rock singer/guitarist.

Yes, everything can be sucked in to a black hole, even light
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.
