I've got a pair of Zeiss. They were my first pair of prescription but could not get on with them at all. Felt disoriented. Other makes also caused same problem. Ok with one eye at a time, but woozy with both. Ed Lyons made me some, same problem, then he found me a very flat lenses Oakley pair that were 95% good. I now have a modern Pilla pair, 97% good, which I bought for the tint on dull days. Only Specsavers are 100% optically perfect for me! Weird. I suspect this may be because the lenses are less curved than any Pilla, which my brain seems to get upset by.
