"Bi-ocular" typically refers to a type of binocular vision where both eyes work together to focus on an object. This allows for greater depth perception and improved visual acuity compared to using just one eye.
The word Biocular means two eyes in Latin language.

The eyepiece of a microscope is called the ocular lens. It is the lens closest to the eye of the viewer and is responsible for magnifying the image produced by the objective lens. The ocular lens typically has a magnification power of 10x, and when combined with the magnification power of the objective lens, it determines the total magnification of the microscope.
