Most definitely metaphoric of his unwillingness to know anything about his sister. Here are you citing "Children of Húrin"? For further readings into the earlier transitions Tolkien has made on this fantastic tale, see "The Book of Lost Tales 2" Volume 2 of the History of Middle-Earth, "Turumbar and the Foalókë." This tale probably would have made more explicit notions of Turin's blindness. He merely is stating that since childhood and [in accord with the Turumbar tale, perhaps not with Children of Húrin, I'll have to check] he has not any recollection or memory of his sister. Such was the evil of Morgoth [Melko in the earlier tales]. Fascinating section nonetheless.
