It's something called evolution. Step processes resulting in complexity. The eye is probably the most well known example.

My favorite Darwin story " The Little Eyeball That Could". There is no evidence this cartoon is true even in the fossil records. So far man has not found any of  these Darwins' "baby" steps which can lead to one eye to another.  There is also more to the eye than just the eyeball.
 I remember reading an article stating the even the simple photoreceptors can tell the direction of the light source. Figure out the direction of the light has more do with the brain than with the shape of the eye. The more the simple photorecepter is pointing toward the light the stronger the signal to the brain.

Euglena, simple photo-receptors (step 1 in diagram)

 

Planarian, cup shaped eyes (step 2)

 

Nautilus, pinhole eyes (step 3)

etc. etc.

 

Wikipedia is great =P

Edit: Also your argument on 'the more the photo-reciptor is pointing towards the light' doesn't work. A photon arriving at a photoreceptor causes the same signal no matter what angle it arrives at. That's the reason for the evolution of the 'pinhole' eye which allows direction to be known.
