Morphology
The components 'optic' (relating to vision) and 'nerve' (a bundle that carries impulses) combine in a straightforward, compositional way to denote a nerve associated with vision. This formation is cross-linguistically common (e.g. Spanish 'nervio óptico', French 'nerf optique'), so a B1 learner who knows the constituent words will readily infer the meaning.
Etymology
Optic nerve gets its name from a simple image: optic means 'about the eye' and nerve is like a 'wire' that sends messages, so the optic nerve is the 'wire' that carries what we 'see' from the eye to the brain.
