Individual humans don't have the capacity to evolve; evolution is a feature of a species as a whole. With that said, I'm not sure what you're asking; do you mean why does eyesight fail? There are a number of conditions which cause eyesight to decline; macular degeneration, nerve damage, brain damage, lack of vitamin A, age, and even good old myopia, which is the medical term for nearsightedness.

The decline in eyesight with age is due to changes in the lens and muscles of the eye, not evolution. Evolution is a slow process that occurs over generations, not within a single individual's lifetime. Factors like genetics, environment, and lifestyle choices can contribute to changes in eyesight.
