Morphology
protanopic = protanopia (opaque) = protan + opia + ic
The word is built from specialized combining forms ('protan-' + '-opia') plus the adjective suffix '-ic', which are technical and not transparent to an average B1 learner.
Etymology
Protanopic comes from the parts protan- and -opic, where protan- comes from a Greek word meaning 'first', as in prototype, and -opic comes from a Greek word meaning 'eye', as in optics. Scientists used protan- for the red-sensing part of sight, so protanopic describes a person or eye that cannot see 'red'.
