those are microscopic strings which float on the surface of our eyes all the closing the eyes & concentrating on our eyelids we see them floating in the eyes.( due to water on the eyes surface).

They're not floaters. Floaters don't move around much. Those are called flying corpuscles. White blood cells (which are part of your immune system) are much bigger than your red blood cells (which carry oxygen). Under the right conditions, you can see the white blood cells moving through the blood vessels in the layers with your retina. A clear or evenly overcast sky provides good viewing conditions to see them, but sometimes you can see them other ways, as you have discovered. If you cough, they'll move much faster because you have temporarily raised the blood pressure in your head, making the blood flow faster. It's all completely normal.
