Why do we close our eyes when we kiss somebody?

Had your eyes wide open, why were they open?"

Apparently, we close our eyes as a kind of instinct I guess. The theory behind it is that by closing our eyes, we "lose" a sense and so enhance all the others, albeit not by much. So we close our eyes to make the kiss feel better and more sensual.
Whether or not there's actually fact behind this, I'm not sure. I just heard about the suggestion of such logic.9
