Why limit the complaint to the back and the eye? Virtually every part of the human body can and does develop problems. Many parts of the body are grossly inefficient. Look at the kidney. Arguably, the closest the body ever comes to physiological perfection is at age 12, and even then it has so many vulnerabilities. Of course, the worst thing of all about the body is that it is mortal, and that's what I believe all these other complaints come down to. Nobody who has ever lived has been capable of designing anything as complex, resilient, long-lasting and versatile as the human body -- and yet we all consider ourselves sufficiently expert at design to critique it. Armchair quarterbacking is apparently another built-in feature of homo sapiens.

The problem with your contention is that we are born with the back and eye problems -- they don't develop as we age. If you believe in Adam and Eve, they had these problems from the moment they were zapped into existence. Evolution has no problem with the cobbled-together aspect of the human body -- as a matter of fact such an aspect would be expected of the trial-and-error approach of evolution. However, for folks who believe man was made physically in the image of God there are some decidedly nasty implications of our physical inefficiencies.
