oculars
Where you peer through
Oculars are the eyepieces of an optical instrument—the lenses you look through on a microscope, telescope, or binoculars.
The term appears in technical contexts where precision matters: The microscope's oculars provide 10x magnification.
In older or literary usage, ocular as an adjective means relating to the eyes or vision: ocular evidence, ocular proof.
