Morphology

dioptric = diopter (opaque) = dioptr + ic

The adjective is formed by the regular addition of '-ic' to the technical noun 'diopter', making the immediate derivation clear.

Etymology

Dioptric comes from Greek parts dia- meaning 'through' and opt- meaning 'sight', the same root you see in optics and diopter. So dioptric describes how lenses let light go 'through' and bend it to change how we see, which is why it means 'relating to the refraction of light and lenses'.
