The LASIK is fine; I think my eyes are just getting older. I've been noticing mild eyestrain/headaches for a few years when sitting in front of the computer screen at work all day, and I noticed that it mostly goes away when I wear glasses. There's supposedly a very mild prescription, but I don't notice the difference without them. Probably more importantly is that they also have a new anti-screen-glare coating on them. I don't wear them much outside of work yet.
