I've never heard an evolutionist say that the eye simply arose spntaniously, it's always been discussed in the form of how it was likely to have developed, from light responsive cells (you have some of these at the back of your knees if memory of jet lag treatments serves) through to more developed organs.

Cells are very canny things, as you know whenan embryo is growing you start of with stem cells, stem cells have the ability to become anything, Skin tissue, liver tissue, eye tissue etc.
There smaller organisms that when required can change their cells back into stem cells and use them for different things when required.
Not forgetting creatures that can spontaneously change sex and grow back limbs
I'm not saying that cell in creature just spontaneously became eye tissue, but the scope is there for them to change for the benefit of the organism. Life is all about having the edge on your competitor for food and survival, one one organism started producing light sensitive cells, so would others and the complexity would increase through generations until you had the wonderful organ we know have.
Lets not forget that insects deveoped eyes but in a completely different way, a way that suited them. I would have thought if one person was controlling what organs we had he would have given insects small versions of our eyes - mean if the eye is so complex and difficult why would you throw out the design you'd spent ages doing?? and go with something completely different.
Also what of the mole a creature that lives underground all it's life - Wht does it have eyes, the eyes it has are bordering on useless. That's not very intelligent design is it?
If the mole was a creature that had been designed to do the job it does why was he given eyes. Unless of course once upon a time he didn't live underground, but then saw a niche market for a mammal that could live underground safe from predators?
Also evolution moves at different speeds for different organisms. We're very complex and therefore changes to use are relatively slow also we are a special case as we don't need to evolve very much any more becuase we have the power to change the environment around us. However, we are all getting bigger - I'm 6'5" and would be considered a giant of a man only a couple of hundred years ago. How tall will my desendants be in say 50,000 years
Bacteria/viruses because they are simple organism and their life cycle is short and reproduction cycle high can evolve very quickly - MRSA has become resistant to penicilan very quickly and viruses can change to airborn variants quickly.
The evidence of an organisms ability to change their physical properties are all around us today
