Optical or Light microscope
An optical microscope uses a system of (usually) glass lenses to focus the small amounts of light given off by the subject into your eye.
Adjustment knobs are used to focus light in a light microscope.

a droplet of water, on a leaf for example, will magnify the view of the leaf. A very light spray of water on the surface of your TV/monitor will reveal the colour phosphors. VERY LIGHT SPRAY! This process is caused by refraction of the light waves. In a light microscope this process is replicated by glass lenses.
On a light microscope there is the coarse adjustment knob and the fine adjustment knob
Optical microscopes use refractive lenses, typically of glass and occasionally of plastic, to focus light into the eye or another light detector. hope it helps... kinda
A magnifying glass has one lenses and a compound light microscope has 2 lenses
The objective lenses on a microscope collects light and brings the specimens into focus.

A microscope contains one or more glass lenses that refract light that passes through them. Both microscopes and magnifying glasses utilize convex lenses.

A compound light microscope.
The simple answer: the lenses focus the light passing through them so that it magnifies what you see. The lens portion of a microscope works just like a magnifying glass, or the lenses in binoculars or telescopes. They also help focus the light in the same way a person with bad vision uses glasses or contacts, to make the image clearer. Note: there are more parts involved then just the lenses in a microscope. However, I am not an expert and cannot say for certain what all is involved.
