Eye floaters are small shapes that seem to drift across your field of vision. They might look like spots, threads, or squiggly lines, and they become especially noticeable when looking at a bright background, such as a clear sky or a white wall. These shapes move as your eyes move and can seem to dart away when you try to focus on them.
