Ocular lens is a type of eyepiece that is attached to a variety of optical devices such as telescopes and microscopes.
There are more than one type of light microscopes as well as other types of microscopes such as the SEM. The first microscopes were (and still being used) are the simple light microscopes. The compound microscope has that name because it contains two types of lenses that function to magnify an object. A simple microscope is a microscope that uses only one lens for magnification. It is the original design of the light microscope. Van Leeuwenhoek’s research used this type.
The type of microscope that you are looking for is known as a "compound microscope."A pair of lenses includes the objective lens (one or more) and the eyepiece lens.
The simple microscope, defined as having one lens, was enhanced by Leeuwenhoek. Many of the compound (multiple lensed) microscopes were blurry, but Leeuwenhoek ground his own lenses.

If a microscope has more than one lens, it is called a compound microscope.
Microscopes are devices which use lenses and illumination to make small things look larger and to make target objects (= things that you want to see magnified) more clearly visible. Generally, microscopes are made up of a number of different lenses which work in combination. With the illumination system, the way that the illumination is applied and the type of illumination can be changed, depending on the nature of the object to be looked at, to make it appear clearer. Regular microscopes mainly consist of two types of lenses, an objective lens and an eyepiece, as well as a stage to place the target object on and illumination system. The object that is placed on the stage is first magnified by the objective lens which is close to it. It is then further magnified by the eyepiece, making the object look larger. more
Pretty much any type of scientist uses microscopes. Microbiologists, paleontologists, pathologists, and many more.
The focal length of the lens and the distance between the lens and the object.
Microscopes, telescopes, slide projectors and magnifying glasses (if appropriately sized) will magnify times 10. The magnification is determined by the type of lens and in some instances, distance.
