Mine changed at EXACTLY 10:07 AM on Friday, February 13, 2004. I was not quite 44 years old.
That was when I had lasik surgery
Doc told me that when he fixed my distance vision I WOULD need reading glasses. Up until then I had to take my glasses off to read. So now I wear cheaters.
I'm still glad I had the lasik even though I still have to wear glasses part of the time. I can drive without glasses, I can buy cheap sun glasses, I don't have to swap from regular to sun glasses, I can see in the water when I swim, I can see the alarm clock first thing in the AM.
