目を閉じて、いろんな君、瞳の奥におさめました。

This 収める. I just can't understand... Does he see them (memories) or, on the contrary, tries to preserve/remember them?

目を開けているといろんな景色が見えて，愛しい人を見た景色をが上書きされてしまう．そんな気持ちから，目を閉じて，君を見た景色を瞳の奥に閉じこめた．収めた．強く記憶したとういうことです．
When I open my eyes, I see all kinds of scenery, and the scenery I saw of my beloved is overwritten. Because of this feeling, I closed my eyes and locked the scenery I saw of you deep in my pupils. I've captured it. It was a strong memory.
