after being near-sighted for all my life I've seen my roommate get LASIK... and her sight got way worse at close distances. which is why I'm now happy to be mildly near-sighted (around -3.5 D), and not going to correct it at least until I start getting far-sighted with age
It also makes me want to finally figure out how to get chromatic-aberration-free glasses, since I probably won't get to escape this rainbow fringe hell with surgery.
