Had LASIK about five years ago. Mixed feelings. Still somewhat glad I did it, though I wear glasses with .5 prescription in both eyes to make sure vision is perfect and to filter polarize the light, etc.

If you're a programmer or staring at a screen, I learned recently that you blink something like 1/5 as much as normal. This in turn causes eye dryness and potential irritation.

So for a while I thought that LASIK had something to do with it, in my estimation, it contributes some to it -- but being a programmer is always going to require being careful with your eyes (giving them rest, doing activities where you naturally blink more, etc.).

If they tell you that your pupils are near the limit (if they're too big, then LASIK -- because it only shaves the top portion of your lens -- won't cover things completely when your pupils dilate -- e.g., at night).

So I've been happy for the running that I can do now. But it's not perfect and I wear glasses when I work.
