When two lenses are in combination.

enter image description here

what logic is it to take the image of first lens (which is not formed in real) as a virtual object to the second lens ?

    $\begingroup$ What does "real" mean ? (rhetoric question) The light rays exist before and after what you're calling the "image". The "logic" is just a mean of calculus/drawing. $\endgroup$ – TZDZ Nov 24 '14 at 15:56
