I got completely off topic in my above message! The point I wanted to make was that the prescription parameters are the same in Germany as here, like I wear a Ciba dailies aqua comfort plus in the right eye plus 3, and the base curve and diameter are set for that particular lens so if I were to purchase them in Germany I would buy the exact same prescription as I wear here. I did not know that our brands were the same as in other countries, I thought they would have their own common brands but maybe they do and the vending machines are likely found in airports! Or train stations? Maybe they are the same all over the world?
