Place a small amount of lens-cleaning fluid on a clean sheet of lens paper. Make one small circular pass on the lens and toss out. If lens is still dirty - repeat.

A pair of spectacles, or a monocle.
The telescope has an object lens at the top, which is a large lens with a long focal length. It produces an inverted image of a distant obect at the focal point. The eyepiece is a smaller lens, and you look through the eyepice at the image formed by the object lens. The image is formed in space, it does not need a screen, and you can see it with the eyepiece. The ratio of the focal lengths of the two lenses is the linear magnification.
objective and eyepice lenses.
what does meaning eyepice WF 10X/20
The eyepiece is located at the top of the microscope where you actually look into the microscope.
In a light microscope magnification is varied by using different lenses to refract the light. In an electron microscope magnification is varied by altering the configurations of magnetic fields to bend the electron beam.
It is lens. The lens consists of the lens capsule, the lens epithelium, and the lens fibres.
The ocular is the upper lens and objective is the lower lens
