What could cause sudden blurry spot in vision?

Seeing black spot out of my left eye?

• For a few months now I have been seeing black spots/ blurry specs out of my left eye. I have had a mild bruise under my left eye as well for just about as long as the specs I have been seeing and it wont go away. What could be causing this and should I be concerned? Could the small mild bruise under the eye have anything to do with these spots I am seeing? Could it just be floaters? And if they are just floaters are floaters dangerous? Sometimes I close my right eye and follow the black spot/spots and it gets me dizzy and usually disappears around my noise. I often have headaches as well. Other information if anyone thinks any of this info could be have caused it or should be alarming as well please let me know. Sometimes its just one spot sometimes a few. I have a very small mouth and have jaw/wisdom teeth problems that come and go. A few months ago I had so much pressure from the top of my head all around my face. It didn't seem like it could be wisdom teeth (my actual wisdom teeth always hurt a little) it would cause the worst jaw pain face pain eye pain and noise pain. It would come about every 30 min and last about ten... the worst pain of my life. My left eye would tear like I was crying, and I would check the mirror to see if my nose was pouring blood because of the nose pain as well. I thought I was having some sort of tumor but then my wisdom teeth started aching horribly again so I thought that it was just from wisdom teeth. I took an antibiotic and things got better. A few weeks ago my wisdom teeth started killing me again, the actual tooth as well. But more my jaw ear and eye. I could not eat and could barley open my mouth not because of the tooth pain but because of how sore my jaw was and my mouth would barley open.. my jaw wouldn't allow it to. My teeth and gums were also killing me and my cheek was horribly swollen. Are these wisdom teeth plus jaw problems? Antibiotics at first wouldn't help but finally did or the problem just went away and will soon come back. I get very dizzy very easy, tired, disorientated at times as well. I wake up in the middle of the night with a zoom sounding in my ear and jump. So I am not sure if it is wisdom teeth problem, a tumor or wisdom teeth as well as more serious problems. I was also dropped very hard on my head by accident by a friend at the nas car race a few months ago, and that's when I really noticed the mild black eye as well as the spots. I know this is long but I would appreciate any answers I am very scared! Thanks! I also can tell when I close each eye that one eye gets better vision than the other, and I know I need glasses if that could be causing the spots.
