Your asking a Korean-English translation question in a French section :-) Anyway, there may be two ways. For example, to say "그녀는 눈웃음을 지었다" (or ...눈웃음을 쳤다, which is the same). - She smiled with her eyes. - Her eyes smiled.

Here is not Korean section. Anyway, "눈웃음을 짓다" is "smile with one's eyes" in English.
