Both.
Their correcting effect comes from refraction, unwanted shine and "ghost" images come from reflection.
yes sometimes they do.

Refract light. They only reflect when you see a glare or ghost image
a lens will refract light. a mirror will reflect the light.

The most refractive color is white, so the whiter U are the more U will refract/reflect~
A prism refracts light, and a mirror reflects light.

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.
