I would say the answer to this is a very definite yes. I can recall instances - very few, unfortunately - when my eyes met with a woman's in such a way that it seemed we touched at a very deep level, a soul level; a place where the love was almost palpable. In both instances there was very little talk, just an 'in the moment rapport' where there was a sort of unspoken understanding that this was a moment to be cherished. These rare moments - rare for my in my seventy-eight years anyway - are remembered life long.
Yes, love can certainly be expressed through the eyes.
