See you say that, but evolution is a slow process and is ongoing, and is a blind idiot god dancing to a tune which has no consistent time signature.
Unless a mutation is heritable enough/commonly occurring enough, and useful enough when it is only a minor change it won't be selected for. It might continue on and become useful eventually anyway if it isn't a detriment and that genetic line just happens to continue.
Why do our bodies age? Because a collection of little mutations that are only detrimental years after reproductive maturity it turns out don't have a huge impact on the survival of those genes.
Why can't we see as many colours as bees? Evolution figured that out for them.
Why hasn't evolution figured out how to give us night vision or an extra set of clear eyelids like camels have? Those would be useful. Animals exist with all those traits so they are entirely possible. If you're objection is "evolution would have figured it out" you only need look to the animal kingdom and see how crappy humans are in lots of ways to realize that is a pretty crappy objection
