Aargh. . .apologies for opening this thread again, but I guess I'm not the only one who is more"bat's eyes" rather than "cat's eyes".Well finally today nature added insult to injury and I have to swap my specs for something a bit more complicated.What is all this CAA stuff (" Bifocals with a small 'D-segment'are prefered to 'execs'because they allow proper distance correction of the runway peripheral vision 'streaming'cues when landing an aircraft")about.Is the choice really 50 40 30 20 10 kiss whilst looking like an old fogey ,or 50 20 graunch but only having to dye/thicken my hair to avoid looking my age;or is it not that simple.My (French) optician tells me she has numerous Air France pilots as clients,and they all opt for "verres progressifs"(well they would wouldn't they!) I just want to know what is most likely to damage my vanity,looking a bit "ancien" or planting the b*gger instead of my usual immaculate arrivals. . .ahem.
