I underwent Lasik surgery a little more than four years ago. It was great! After 20 years of glasses/contacts I was finally able to see again and see quite well. I know from the experience of the past several years that my vision is excellent.
It is superior to many of the people around me which is why I get especially irritated when I encounter blogs that are not user friendly. They have strange colors, fonts that are intentionally mismatched and all sorts of other crap that just gives me a headache.
In my book they are right next to the people who constantly have to blog about their cats, which is to say not very high.
