I am another .........
started flying at 16.. wore trendy(for the 1970's!) black horned rim glasses.
The prescription changed several times until I was 22, and been about the same ever since............
I am -4 in one eye, -6 in the other and wear toric contact lenses(astigmatism as well)
FLOPT- I too started having problems reading small print at about 47, had to get 'look overs' at 48, held off the doc at arms length re putting 'reading glasses required' on my medical until I was 51 (now 53)
I have considered laser treatment, but I tolerate contacts well, I really need my class one, so surgery to me is a last resort, I dont want to take the risk....................
Cheers
