Morphology
The meaning 'the primary region of the brain for vision' is directly and compositionally derived from 'first' (primary/preceding), 'visual' (related to sight), and 'area' (region), so a learner who knows the constituent words can infer the general sense. Although it is a technical term referring to the primary visual cortex (V1), the relation between the parts is transparent and cross-linguistically predictable.
Etymology
The term first visual area comes from a simple image: imagine a relay where the eyes send signals to the very first station in the back of the head. The words first, visual, and area show it is the 'first' brain 'area' that begins to process what we 'see', so the name means the brain region that first receives and starts to process what we see.
