喜樂美語
  1. 1眼睛的、視覺的（書面；口語多直接說 eye）。常見於「視神經」optic nerve。

    Optic is a formal, scientific word. It means 'about the eyes' or 'about sight.' You will almost never hear it in a shop; you will see it in hospitals and textbooks. The optic nerve is the line that carries messages from the eye to the brain. If that nerve is hurt, a person may not see well even when the front of the eye looks fine. Everyday English prefers eye: eye doctor, eye test, eye strain. Optic stays for the technical bits. It is close to optical, but not quite the same: optic to the eye itself, while optical often talks about light, lenses, and machines.
