new floaters in my eye since I fell.

I fell and hit my head a while ago. I realized that I had a lot of new floaters in my right eye since I fell. I saw an ophthalmologist. He said everything was healthy and no damage was done. However, since the new floaters, that eye has felt heavy with added pressure. It feels like my eye lid is drooping. There are no physical changes or visual changes (except the floaters). My question is, do floaters generally cause the eye to feel heavier? Or is it possible that the eye may be strained because it is trying to see through the floaters? Any similar experiences?
