I'm sure that they work well for many prescriptions, but not for me. The illustration I was drawing was that even if you are willing to pay for 'the best' you can still run into issues with CA. I have also tried other high refractive index glass with the same result. I too was told, just wear them and you will get used to them, that is not the case - 3+ months of wearing them resulted in buying significantly cheaper but 'better' lenses.

(The worst were from Ziess.) You would have done better to avoid off-brand knock-offs like "Ziess" and to buy honest-to-Ernst Abbe Zeiss eyeglasses. Zeiss eyeglasse lenses are made, incidentally, at the former Zeiss Ikon plant in Stuttgart where the Postwar Contax IIa and IIIa cameras were made. My wife went over to Zeiss at my recommendation seven or eight years back and has been most happy with them. I use whatever the VA hands out: they were Rodenstock lenses the last time I got a pair, and they are perfectly satisfactory.
