It doesn't work for everyone. I've been stable at a refraction of
OS -6.75 sph -1.00 cyl
OD -5.25 sph -0.50 cyl
for most of my adult life.
I'm 36 now, and have had an FAA Class 1 since age 19, which had been issued on a waiver at
zero hours logged. Back then, the FAR 67 requirement was a DVA no less than 20/100 uncorrected, correctable with glasses to 20/20 or better in each eye separately (my DVA was --- and still is --- 20/200 correctable to 20/12). We have since eliminated the uncorrected DVA minimum altogether.
Fortunately, my country has
never imposed a refraction requirement for issuance of a medical certificate (at least for civilian pilots). The whole idea of failing someone due to the prescription of his lenses --- even though his eyesight is correctable to normal parameters --- is utterly ludicrous when one thinks about it. Give it another year or two... your government may very well change the rules in your favor. If not, you can always take your business elsewhere.
