Dear friend, the remains of dead cells on the surface of our eyes will have reflections on the retina and cause black spots in our vision. Most of us will have eye floaters and it is a common phenomenon. If you just see a few eye floaters in your vision, you needn't worry about it. Our brains will learn to adapt to it slowly. If you just have an eye surgery in one eye, you may possibly have eye floaters in this eye. But it will go away slowly after the remains of the tissues or cells on the surface of your eyes were washed out by tears.
