To look someone in the eye 这个短语的意思就是你双眼直视对方，让对方相信你所说的话是完全真实的，即使你有可能并没有说实话。

例句

John looked me in the eye and told me that he loved me.

I looked at my boss in the eye and told him exactly what I thought.

请注意

如果英语里碰到 more to something than meets the eye 这个形容方式，意思一般是“某事/某物其实另有文章”。

例句

I don't like Jane's new husband. He seems kind and gentle but I think there's more to him than meets the eye.
