Exposing too much to mold can cause you eye irritation, headaches, sore throat and some other symptoms. There is no direct connection between mold exposure and eye floaters. Eye floaters are very common in people's eyes. I have floaters in my eyes too. Usually, Eye floaters will stay in your eyes for a long time, they are harmless, try ignore them.
If the floaters have affected your vision, you need to see your doctor to find out the causes. There are different causes which lead to eye floaters, some kind floaters can be reduced, and some are not. Some times a dietary change can help to reduce floaters. Reduce your stress if you are stressful. Medical surgery can get out the floaters effectively, but you need to get your doctor's permission. Anyway, if the floaters are little and cause no much inconvenience, you’d better learn to live with them. Good luck!
