Transient fogginess is not always floaters. This came up on another forum here:

Thickened tears may give an impression of floaters.
But real floaters, come from tissue holding the retina in place.
They are mostly transparent, and may have black dots in them (which are blood specks).

Real floaters can precede a retinal detachment. Typically a flurry of them usually affect each eye at different times. People who are very nearsighted have a higher risk of retina detachments than others because their eyeball is not round, but oval. So the tissue is stressed, and may detach if you get a head bump from a fall or a car accident.

For floaters inside the eye (the real ones) you can close your eyes and roll them around a bit, and the floater will spin beyond your pupil along the sides, and you will not see it as much.

For momentary blurriness from thickened tear substance, getting some artificial tears usually clears that up...choose a brand that says "preservative free" on it.

Many drugs can cause thickened tears, and so can dehydration.
Getting older will do it too. Sometimes it is an autoimmune problem (Sjorgren's) as well. If you have allergies, you may get some blurriness too. Choose an allergy med like Claritin or Allegra, as these don't blur vision like other drying antihistamines can.
