Need the title of O.Henry Story

I've been looking for a story about an aging couple that give gifts to each other. IT'S NOT "THE GIFT OF THE MAGI" but is similar in some ways. She gives him a gift to match his blue eyes --they are still blue to her but are clouded now, maybe cataracts. He gives her a gift to match her hair color (red I think) but it has turned gray. In other words, they don't see that the other has grown old, they see each other as they were when they fell in love. I need the reference for a piece I am writing about couples that reconnect after many years, very grateful for help. Sonoma
