I think I may have the same problem. I have had floaters since about a year ago and when its bright they are more apparent. I also see small dots probably like what you describe. This problem is only in my left eye. Also sometimes when I work on the computer too long my left eye gets tired and I feel a slight deep pain, although this may be due to stress also.
I don't really have a pain in my jaw and it doesn't bother me when I eat, however when I move the bottom part of my jaw left and right I hear a cracking sound coming from the left end of my jaw joint. Probably sounds like when you crack your fingers. I am not sure what you mean by popping your jaw, do you mean the same thing?
When I first had those symptoms I was extremely scared but luckily since then they have stayed constant. I never visited a doctor because I have an extreme phobia with doctors so much that I instead sit and waste my time worrying about it.
Does this sound like tmj also?
