The first sign that I was growing old is the hone-wear on my forehead and temples... /rimshot...
Seriously, though... My glasses prescription is 10.25 and 10.75 (left, then right, respectively)... My father is 57, and has had glasses since he was 24... His prescription is (again, respectively) 4.75 and 5.75... I wear COKE BOTTLE glasses!!
According to my Eye Doctor, I'm a prime candidate for Lasiks surgery... Or a legal blindness card...
I shutter to think of my eyes when I'm, no offense, you guys' ages...
