Andii, I can see my floaters in any kind of light. Its just that they are less obvious in less lighted places. When I am watching TV in a lit room, yes I can see floaters. When I am watching TV in a dark room, I cant see floaters easily but they pass in front of my eye then they create a smearing/fuzzy/blurring/distorting effect for microseconds. Especially in the right eye as I have a very dark blob. I am sure this is due to different refractive index properties of this circular blob as it is quite dense.
