“a sight for sore eyes”是啥意思？

一说到“sore eyes”，有人可能又会想到另一个俚语“a sight for sore eyes”，“sight”是“视野、视线”的意思，那这个俚语的意思是指疼痛的眼睛的视野吗？
肯定不是啦，这句俚语的英文释义为：“a way of saying that you are very pleased to see someone or that you think someone is very attractive.”
中文理解为“乐于看到的人；极有吸引力的人”。
其实直接理解为眼睛疼还想看到的景象或者人或者物，是不是极其具有吸引力？因此见面打招呼时就可以用这一句特别口语化的寒暄语：You're a sight for sore eyes（见到你真好）.
与a sight for sore eyes相近的意思还可以这样表达：
You're just the man I want to see.
你正是我想见的人。
It's really great to see you.
见到你真是太好了。
I didn't expect to see you here.
我没想到会在这里看见你。
