If you look at the history of the eye, you will see that in any environment that includes some form of light, natural selection generally favors specimens that have developed some sensitivity to it. Apparently it offers a strong evolutionairy advantage. This is probably true for alien lifeforms as well. Wether they have a completely different 'blueprint' than DNA is irrelevant, if there is a form of mutation + nat selection, it will favor the early eye. Unless, as Dawkins states, the environment is utterly different. Like a permanent fog or extremely deep waters. At least as I understand it.
Edit: I'm really tired, so please correct me if I'm not making any sense.
