types of eyepieces in light microscope
A compound microscope has two lenses - the eyepiece lens and the objective lens. the objective lens(which is a convex lens) collects light and brings it to focus, creating an image. The eyepiece lens is placed at the focal point(the point at which light rays meetafter passing thru the convex lens). Thus we are able to see the magnified version of the image.
Using just the light is not enough. Using shorter wave lengths will allow you to see them.

The magnification power of the eye piece on a light microscope is usually 10x but it can vary for each microscope
For a compound microscope iss; light source, diaphragm, stage, (slide), objective lens, body, eyepiece, eye.
Viruses are too small to be seen in a light microscope.

The answer you are looking for is called a dissecting or stereo microscope. These provide a lower magnification range in comparison to compound microscopes and they use two sets of lenses, the eyepiece and the objective lenses. these then provide a 3D image.
The main parts of an optical microscope are: the eyepiece, objective lense and light source (sometimes a mirror). The objective lense has a short focal length so it produces an image a little bit up the microscope's tube which is then magnified by the eyepiece. Resolution is dependant on the numerical appeture of the lense and the wavelenght of the light source used.
The aperture in the stage of the microscope changes how much light comes through to the eyepiece.
The power of a light microscope can be determined by multiplying the magnification power of the eyepiece by the magnification power of the current lens. Ex. (10x) by (40x) results in in a 400x magnification.
