Just happened to me. I had LASIK back in 2005 when I was about 22 years old. I was legally blind without glasses or contacts. LASIK got me to 20/20 and 20/15, basically 20/15 combined. 9 years later, my eyes have started to deteriorate again. I was able to squeak past my last 2 first class medicals with no glasses requirement, but this year (2 weeks ago actually) I was unable to read the 20/20 far sighted line...my near vision is still crystal clear, it's the far stuff and especially at night when it gets bad. I'm now the proud owner of a glasses restriction on my medical. I'm only 31...eat your carrots kids!
