In addition to D-R answer: "In your eyes" can be translated as בעיניים שלך and also as בעיניך. From practical point of view there are some differences between the two options: בעיניים שלך - More colloquial, can be used as a kind of swear (or asking somebody to swear "in his eyes"), or when we refer really to the eyes (Doctor: "I didn't find any problem in your eyes, you are OK"). בעיניך - More literally, and is used in the meaning of "your opinion". For example - ?איזו חולצה יפה יותר בעיניך.

בעיניים שלך Для м. - шелха Для ж. - шелах
