It is referred to as the working distance.

You should use the lowest value lens. It is the shortest one.
The function of the eyepiece is to allow us to observe the specimen in a microscope. It multiplies and adjusts the magnification of the objective lenses. Sometimes, it even corrects aberrations of the objective lens.
The course adjustment knob must be turned forward only while watching from the side to ensure that the microscope's objective lens moves closer to the specimen. This allows for focusing on the specimen and achieving a clear image. Turning the knob in any other direction may result in moving the objective lens away from the specimen, leading to an out-of-focus image.

the distance between the specimen and the objective lens
working distance
An objective lens gathers light passing through the specimen on the microscope and projects the image into the body of the microscope. Objective lens are closest to the specimen.
Convex lens or low power objective
The working distance is the distance between the cover slip and the bottom of the housing fo the objective lens.
Under the objective lens there is a stage to put the specimen ( the thing you want to look at ).

The magnifying system in a microscope typically consists of the objective lens, eyepiece lens, and sometimes a condenser lens. The objective lens is responsible for capturing the image of the specimen, while the eyepiece lens further magnifies the image for the viewer. The condenser lens helps focus the light onto the specimen for clearer viewing.
The low power objective lens is usually a 10x lens and it is used to orient the specimen and get it focused before switching to a higher power lens.
