It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power

If you are talking convex and concave, they both have an optical lens. Sorry if that doesn't help, but what do I know.

The design uses refraction of the objective lens to form an image. This image is then observed with a second lens to allow the eye to see it. Except for the types of lenses used the same principle is used in optical telescopes and binoculars.
