In darkness I have a dark spot in center of vision. Shows up very little in light. Everything is very dark when trying to drive at night. Almost blind! Trouble started about a year ago. Had all kinds of eye tests. Found nothing wrong. What next?
If I close either eye it's still there. Anyone have this problem?

Do you get flashes of light in your vision? Yellow-white sparks? If you only get them once in a while coughing, don't panic. But if they show up and don't go away, see a doctor within 48 hours.
Lots of people have floaters, as StandingAlone says. They are little dots or threads or circles floating in the vitreous fluid of your eye. If you get a sudden change, either a new large one or a shower of pepper-like bits, this is called a vitreous detachment, and is kind of an emergency. If I remember correctly, you should go at once to an eye doctor, or even the ER. It isn't always detached retina, but if it is, you want it to be treated ASAP.
I had a spot in the middle of my vision - very tiny - which grew into a cataract. I have pretty huge floaters, which bother me most at night and in really bright light, when my pupils are very large or very small. They are more dark and translucent, not really black. Detached retina will show up as a dark spot in your vision, but it would probably be there most of the time.
I would assume that if experts can't find it, it's probably a brain or nerve issue. Make sure your blood sugar and blood pressure are OK, and maybe it will never get any worse.
Sometimes we have to settle for not getting any worse.
