The primary purpose of tears is to clean and lubricate the eyes.
Tears are secreted from the lacrimal glands through ducts to the surface of the eyes between the eyeball and the lid.
The lacrimal gland, one for each eye, is located at the back of the top eyelid. When we blink, tears known as lacrimal fluid, are distributed over the eye surface.
The lower eyelids have minute orifices called puncta on their margins and bottom corner that collect tears and pass them down to the inner nose.

They are generally easiest to see when looking at plain back grounds such as a clear sky or a light plain colored wall.
The floaters are actually small pieces of gel or cells that are inside the vitreous fluid. That is the clear jelly like substance or fluid that is found in the inside of your eye.
