What are objects floating like worms in human eyes?

Have you ever seen something floating in your vision? It is like a worm or it can also be a transparent water. But strangely, you keep trying to see more clearly, it disappears and when you look away, it appears.

• What is the world in the eyes of young children under one year old?
• The reason why the eyes wake up every morning and full of rust will surely surprise you
• In the future, these excess body parts may completely disappear due to evolution

Don't worry, they're not a living organism or an eye defect, but a piece of tissue, red blood cells or protein clusters in the eyeball. When we look at the sky, floating objects appear to be a very normal thing that everyone faces.
