Morphology

anisometropia = metropia (opaque) = aniso + metropia

Built from Greek combining forms ('aniso-' + 'metropia') that are technical and unfamiliar to average learners, so the parts do not help derive the meaning for a B1 learner.

Etymology

The word anisometropia breaks into aniso- meaning 'unequal' and -metropia which links to 'measure' and eye 'sight', like the familiar myopia and hyperopia that end in -opia meaning 'sight'. So anisometropia is 'unequal' focusing between the two eyes, which is why each eye may need a different lens.
