Morphology

emmetropia = emmetro + opia

Built from Greek combining forms (emmetro- 'well-measured' + -opia 'vision') that are technical and not productive in common English, so an average learner cannot derive 'normal vision' from the parts.

Etymology

Emmetropia comes from Greek parts: emmetro- meaning 'in measure' and -ia meaning a condition, and the idea is the same as the English word measure. So it literally says the eye is 'measured right', which is why emmetropia means normal, clear vision without glasses.
