Ocular lens- part of a compound microscope that a user looks into to see a magnified image. It is a see through doubled lens curved to cause images to appear larger.

Why don't micorscope makers use 100x ocular lenses?

YES
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.
When needing to make something larger you will need a microscope. A microscope has two lenses; one being the objective lenses and the other is the ocular lens.
Ocular in this context means eyepiece - the piece that is closest to the human eye that is watching.
Contrast is the difference in light and/or gloss that hits an object distinguishable. In ocular perception of the real world, contrast is resolved by the difference in the color and brightness of the object and other.

Ocular micrometers are see-through disks with a ruler in them that go in the eypiece of a microscope to measure what you are seeing. Stage micrometers are put on the stage/view platform of the microscope, so instead of putting them in the eyepiece you are putting them right next to the object you are looking at in the microscope.
the ocular lens sits higher up, closer to your eye. the objective lens are in the objective tube below the ocular lens
