What makes the objective lenses and eyepiece of the microscope similar at the same time different in function?

Both the objective lenses and eyepiece are used to magnify the image in a microscope. The objective lenses are responsible for capturing the initial image and focusing it, while the eyepiece further magnifies and projects the image to the eye of the viewer. The main difference is that the objective lenses have different magnification powers and are adjustable, while the eyepiece usually has a fixed magnification.
