Instead of looking at each other, Clare and Francis looked in the same direction, and we know what "direction" that was in their case. Clare and Francis were like two eyes always looking in the same direction. Two eyes are not just two eyes, I mean, not just one eye repeated. Neither of the two eyes is just an extra or a spare eye. Two eyes looking at an object from different angles give depth and relief to the object, enabling us to enfold it in our gaze. That is how it was for Clare and Francis.
From this beautiful homily by Fr. Cantalamessa, preacher of the papal household.

hmmm, clara francesca on the brain?
