Their environment is not only the outer world, but the genetic environment the mutations arise in. A light-sensitive cell arises in a brainless animal? You might have a point. It arises in an animal which has a brain? The possibility of processing exists. If it can and does, then you've got a whole 'nother ball of wax.
More creationist binary thinking on display here.
Yes, if: a cell becomes photosensitive through a copying error; the cell is hooked by nerves to a brain; and, the brain by chance directs useful behavior based on the information from the cell, then you have something. Needing all those things is why it's irreducibly complex. You could have a photosensitive cell on your elbow right now. It wouldn't change a thing, because your brain isn't wired to process input from your elbow visually. If the evolutionary view is true we should have eyes on the back of our heads or in other places.
Not "should", but "could have had". Lots of variations are possible given evolution but not all become actual.
