Being able to see is alright.  It lets us avoid predators, find game and watch "Dancing with the Stars".  But compared to most organisms, our eyesight just doesn't measure up.  Everything from birds to squid can see way more than we can, even cats can't be entertained by television. 

Besides eating a few hundred carrots and getting your eyes checked every few weeks - there isn't much you can do to improve your eyesight.  Unless you factor in gene therapy, its always a viable option.  And gene therapy doesn't just improve your eyesight, it might be able to cure blindness and change your ability to see completely.

No word on x-ray vision though.
