Subjective lens and objective lens. Hope it helps :)
maintain distance between your eye and and eye piece of the microscope it helps
You look into it.

If you mean what you see when you look through a microscope, it is called the field of view. Until you place your eye closer to the eye piece is does appear like a white circle.
Assuming you are asking about a microscope (your question is very unclear on the subject), then the body or barrel of the microscope would do this, it would also be the point at which focus movement would be achieved.

Eye piece and . . .lens ;-)
One can calculate the total magnification of a microscope by multiplying the magnification of the eye piece by the magnification of the main scope. For a compound microscope one must multiply each eye piece magnification.
The magnification power of the eye piece on a light microscope is usually 10x but it can vary for each microscope
The eye-piece multiplied by the power of the lens Eye-piece: 10 lens : 50 500x magnification
It is the part that holds the objective lenses in position and at a correct distance with the eye piece
