Small specks or clouds moving in your field of vision. They are caused by pieces of tissue inside of the eye. When light hits these pieces of tissue it creates shadows on the retina that appear to float across your field of vision. It may appear that these specs are on the outside of the eye, but they are actually on the inside. In most cases floaters are no cause for alarm. However, a sudden increase in new floaters may indicate a problem. And an eye exam is recommended if this occurs.
