Yes, best kind.
(clear lets the light through)
it is used in a concave lens
Fresnel lens
convex
a diverging lens can not be used as a magnifying glass becuase a diverging lens( concave) lens diverges the the rays cousing the image to not be erect, but upside down. While magnifying glass ( convex) is used as it is a converging lens which focuses the rays in one point of an objects making it magnifies and erect.( right way up)
Converging, Convex
it is used in a concave lens
a glass one
By "White" I must assume you mean "Clear" otherwise the pane of glass would be opaque. A lens must have some curvature in order to focus light. A flat pane surface does not. The light may be bent on passing through the material, but will not be bent to a focal point, as would a lens.
Fresnel lens
Metal and or plastic frames. The lens are usually clear plastic, rather than the previous glass lens.

no. its lens like glass for you to see far or near
Magnifying glass is used with this lens
glass
Glass was used as a lens protector. Now we use plastic.
A convex lens.
