I only have eyes for you, no one else will do.

(只爱你一个，没有其他人能取代你)

I've been looking for you everywhere. I only have eyes for you.

(我到处都在找你，只爱你一个)

此外，还有一个类似的短语"I only have eyes for you"，它也可以用来表示只爱你一个的意思。例句：

(你是我唯一看到的人，只爱你一个)

I know it's wrong to love only one person, but I can't help it. I only have eyes for you.
