It all depends on if the telscope is a refractor, or a reflector. Reflectors have a convex mirror that bends the reflection on to a flat mirror that angles the magnified reflection to the eyepiece. Refractors use to convex lenses that bend the image and light, magnifying the view to the eypiece.
"Optical", in this case, simply means that they work with light.
Refracting telescope
the reflecting telescope was!!
The refracting telescope was invented around 1608 by Dutch eyeglass maker Hans Lippershey.
"I logged onto WikiAnswers, went directly to the Astronomy category, and immediately chanced upon a new question that challenged: 'Use refracting telescope in a sentence' . "
it doesnt

A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
Refracting telescope
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.

One that you look through, rather than into.
