Leo, the 'they' was a typo. It should have said 'I think they do a good job' referring to the eyes. 
May I say that I don't think it is just an intuitive thing where I 'see' design. My partner is an atheist through and through. He looks at me as if he feels sorry for me if I talk about spiritual matters. I played a trick on him last week when we were debating the flagellar motor. I had a big image on the computer screen of it and said to him: 'what's that?' He thought it was some kind of aeroplane engine or something like that. I couldn't resist laughing and when I told him what it was he looked rather doubtful to say the least. Just maybe, and I've said it many times, the fact it conforms to a high spec, that would make a mazda engineer blush, is because it is actually designed. My thinking and reasoning seem 'set' in seeing things this way. (Just as I would always arrive at the same conclusion if I looked up at the 'shapes' on the side of Mount Rushmore and concluded they were fashioned by some intelligence as opposed to the weather etching them over thousands of years.) I'm prepared to say that evolution takes place but I can't fathom it happening without guidance. I haven't made my mind up about this though so I need to do more studying. Anyway, getting back to the eye:
Adrian, Leo: Two friends have come back to me with these points which seem feasable:
How is the upside down image a problem? The eye still has to send that image data to your brain so regardless of whether it was upside down or not, the data would still have to be interpreted by the brain. Your brain has to work regardless. God could have make the image right side up with an extra lens in your eye, but there would really be no point. Besides, the brain is very versatile. They did this one experiment on a cat where they put some kind of goggles on him that made everything upside down. For a little bit, he couldn't figure it out, but eventually was able to move around normally after his brain adjusted.
Iin order to have an image right side up on our retina we would need another lens to flip it around, requiring another part, needless and inefficient when you consider that the brain can quite easily work within this image that is upside down.
I've got some interesting points on the 'swallowing, breathing' problem if you are interested.....
