    That was a nice read. He really did a good job balancing meaty optical physics with understandable language for the rest of us.

    If you want to go full monty on reading zone area in a Zeiss lens, I think the play would be to go to their Smart Life Individual "N" design.

    My standard response has been: "Do it the regular way because there's no compensation for such position of wear".
