Morphology
tritanopia = tritan + opia
A technical medical formation from combining elements that are not standalone English words, so an average B1 learner cannot reliably infer the meaning from the parts.
Etymology
Tritanopia comes from parts that mean 'three' and 'vision' — tri- ('three', as in tricycle) and -opia ('vision', as in myopia). It is named for the 'third' color sense (the blue one), so it describes the rare color blindness where people have trouble telling blue from yellow.
