I have huge amounts of floater in the morning when my eyes are dry and have thicker tears. Once I have rehydrated (drank my morning glass of water), these floaters resolve. If I start to focus on these floaters, my brain easily gets stuck focusing on them until I find something to distract my brain away from the floaters.

I can tell they are in my tears because once I am hydrated, when I blink, they will move. I have them as dots and squiggly lines. The squiggly lines must be pieces of lint.

It's amazing how much dirty can get into the tears.
