I upgraded my vision with LASIK. First impressions were that my eyesight was as good as when I was wearing glasses, but a week later, it seems to be better than with glasses. Everything looks so clear, and even the colors are jumping out at me more, which I wasn't expecting. Even my OLED TV looks better than it used to, so I think this counts as a home theater upgrade. I have to say I'm really happy with the results.
