The little amoebas you speak of are thickenings in the fluid of the eyeball. I think it was silly of your eye doctor to tell you that you can only look forward to a future full of expanding numbers of floaters. This seems to me an example of medical hexing. If you tell a patient he or she will only get worse, the likelihood of that becoming true is much higher. In some people, floaters stay stable and don't get worse at all.
Most floaters are quite harmless, though they can be annoying.
Their sudden appearance can be cause for concern, and would warrant a visit to the eye doctor. But floaters rarely interfere with vision - your anxiety about them may be making them appear more obstructive than they really are. Inc. All rights reserved.
