For example, look at the fly. the fly moves really fast, so it has to process the information that it sees very fast, so it has evolved to see blurry stuff (it cannot resolve two close points well enough) but it can see ...

Mutations are not performed targeting a specific new phenotype. There is no way an organism can "know" the impact of a specific future mutation anyway. A mutation is just a mistake in the replication process. As a consequence the majority of mutations are deleterious and only a handful of mutations are beneficial. It is true though that the mutation rate ...
