Eyepiece Lens

can a concave lens be used as an eyepiece in a microscope? why?

Any combination of concave and convex lens can, and are used in optical devices such as microscopes. It just depends where the object is, and where you want the image to be focussed at. If you have an object within the focal length (i.e. between the centre of the lens and the principal focus) then you have the useful effect of having a virtual image (that is conveniently magnified and upright) formed on the same side of the lens as the object. Concave lens can be used in microscopes or telescopes within the ancillary optics.
