看起來的樣子
同一條路，換一頭站。不問「怎麼接收」，改問「送到眼睛的那個樣子好不好」，於是整個字就變成專門評論外觀的工具。
r · B2
In the way something looks; used when you are talking about the appearance of a thing rather than about how it works, sounds or feels.
視覺上；外觀上
核心畫面
Words ending in -ly answer the question in what way, and this one answers it with the eyes. Picture a short channel running from a thing to a pair of eyes. Stand at the eye end and you get the plain meaning: doing the job by looking — showing a diagram, checking a bridge, confirming a runway. Stand at the other end, looking back at the thing, and the same channel gives you the appearance meaning: what the eyes receive, whether it is attractive or dull. And when the channel itself is damaged, English says visually impaired.

可以想成一條從東西通往眼睛的短路。visually 的工作就是指著這條路說：走這裡。站在眼睛這一端看，得到的是最字面的意思——靠看的去做事：把步驟畫出來、把橋目視檢查一遍、用眼睛確認跑道。換到另一端，回頭看那個東西，同一條路就變成「它送出來的樣子好不好看」。而當這條路本身受損，英文就用 visually impaired 來說。From the word’s history
Wiktionary records visually as visual plus the adverb ending -ly, so the word literally says in a visual way. That is exactly the channel picture: -ly asks in what way, and visual answers with the eyes.
Wiktionary 記錄 visually 由 visual 加上副詞字尾 -ly 組成，字面就是「以視覺的方式」。這正好對上上面那條路的畫面：-ly 問的是「用什麼方式」，visual 回答「用眼睛」。

這條路受損時
如果眼睛這條路本身走不通或不好走，英文用 visually impaired 來說。這裡的 visually 只是標出「受影響的是哪一個感官」，受損的意思是 impaired 帶來的。
