Obviously the glasses. Contact lenses will protect only the retina of the eye. Rest of the eye is exposed to the dust particles. You should use the glasses which will not allow entry of the dust particles in the eyes. So called bikers glasses. But it is better to have any type of glasses than none.
Opticians typically work with specialized machines to grind and shape the lenses for glasses according to the prescription provided by an eye doctor.
Yes, glasses can have concave lenses. Concave lenses are used to correct nearsightedness, as they diverge light rays before they reach the eye, helping focus the image properly on the retina.
Eye glasses do not contain actual minerals because glass lacks a crystal structure. Most glass is made from quartz.

Yes, using two lenses of glasses 20 diopter. If the distance between lenses is 300mm microscope magnificationis 20X.
Convex Lenses (Plus Lenses): Used to correct farsightedness (hyperopia) by converging light. Concave Lenses (Minus Lenses): Used to correct nearsightedness (myopia) by diverging light.
