Ocular lens- part of a compound microscope that a user looks into to see a magnified image. It is a see through doubled lens curved to cause images to appear larger.
The ocular and objectives
Microscope makers typically do not use 100x ocular lenses because it can lead to image distortion, reduced field of view, and decreased depth of field. Using lower magnification ocular lenses ensures a better balance between magnification and image quality for most microscopy applications.
The set of numbers for known distances between the binocular lenses of the ocular is typically standardized for binoculars. This distance, known as interpupillary distance (IPD), ranges from around 55mm to 75mm for most adults. It is important for proper alignment of the binocular lenses with the eyes for a clear and comfortable viewing experience.

The ocular lenses on a microscope are located at the top of the microscope's eyepiece tube. They are the lenses that you look through to view the magnified specimen on the microscope slide.
The objective lenses of a compound microscope are the parts that magnify the object being viewed. These lenses are located close to the specimen and provide the initial magnification before the image is further magnified by the eyepiece.
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.
No, ocular lenses do not have pointers. Ocular lenses are used in microscopes and other optical devices to magnify the image for the viewer, but they do not have built-in pointers. Pointer devices are typically separate tools used for indicating or highlighting specific areas of interest in a microscopic sample.
Ocular in this context means eyepiece - the piece that is closest to the human eye that is watching.
Contrast is the difference in light and/or gloss that hits an object distinguishable. In ocular perception of the real world, contrast is resolved by the difference in the color and brightness of the object and other.
