Ocular - Binocular
An ocular is a lens or group of lenses that allows the eye to observe an image originating from the objective of binoculars (but also from a microscope or a camera, for example). Or, in other words, it is the lens through which you look. In many cases, the right ocular is often equipped with a dioptric correction system, which allows the ocular to be adjusted to cater for any differences in visual acuity.
