Definition of Ocular
Ocular: Having to do with the eye.
In a microscope, the lens closest to the eye is termed the ocular (the eyepiece) whereas the objective (also called the objective lens) is the lens nearest to the object being examined.
The light microscope today is usually binocular (with one ocular for each eye) and has a turret bearing a selection of objective lens.
