It reflects off of them.
No, they use lenses. :)
A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.

the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
Cameras and reflecting telescopes gather light using mirrors and lenses.
It uses lenses.
The Hubble Telescope uses both mirrors and lenses to focus on images.
They are not mirrors they are called lenses so we can see through them

the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
Mirrors don't refract, they reflect. All lenses, on the other hand, refract (bend) the light. All cameras have lenses, to focus the image; same for eyeglasses. Some telescopes have lenses, but others are collections of mirrors. Note that some few optical elements are lenses and mirrors - like prescription sunglasses with mirror coating.
It is a telescope that uses lenses and mirrors.
On eyeglasses? Two lenses = bifocals Three lenses = Trofocals
