“Why do I see black spots when I stand up?”
I noticed over the last month or so that when I stand up, I often see black sports in front of my eyes for like 10 seconds. What could make this happen?

If these spots are “floaters”, they may exist in your vitreous, if that is what they actually are. Since this may be related to the vitreous or possibly the retina, I would strongly suggest that you make an appointment with an eye doctor in order to have your eyes evaluated, have your eye pressures measured, and have your eyes dilated. This way you can know for sure if this is something that needs to be monitored, watched, or treated. Good luck and best wishes.
Floaters.
Black spots can typically be floaters, but they don’t necessarily occur with changes in posture. Flickering lights when standing or sitting can be caused by changes in blood pressure. Either way, it would be a good idea to get it evaluated.

You will need a retinal evaluation.
Could be vitreous strands/floaters, but could be something more serious like retina detaching, or a number of other possible causes. My recommendation would be to have eye exam with dilation for more thorough evaluation of eye health.
This can be from low blood pressure. Be sure you are drinking enough water and see your primary care physician For a physical and your optometrist for evaluations of your eyes.
Many things. You should have an eye exam and check your blood pressure to start.
Check your blood pressure and hemoglobin
As we age, the jelly-like substance (vitreous) inside our eye becomes liquified, which sometimes causes some of the fibers of the vitreous to separate from the light collecting structure called the retina, and clump together to form small shadows that you see as "black spots" in your vision, which are known as "floaters." Most of the time floaters are harmless, but if you start to see many new floaters or flashes of light (like camera flashes), then it's a possible emergency, and it's time to see an eye care professional immediately!
That's usually a sudden change in blood pressure in the tiny blood vessels in the eyes. We can never assume, so it is important to follow up with your eye doctor.
Low blood pressure/ low blood flow into the eye until your heart kicks up a notch and renormalizes to your new activity. (It is related to Orthostatic hypotension)
Floaters, PVD (posterior vitreous detachment).
