They are made of plastic, right?
Please let us know how good they are. I tried [non-Zeiss]'progressive' lenses a few years ago, and was disappointed in the severely restricted field of view: at least 50% of the mid-distance field was totally blurred and useless. They were inferior to bifocal lenses.
Yes I think they are plastic, I should have put "Glass" in quotes!
I am not sure what you tried, but the ones I get are measured and cut precisely for my eyes and the areas of the lens for near, middle, and far are engineered in a way to not cause any problems like that. I have had this style for 4-5 years and I highly recommend them! They are high index, meaning very thin (1.67 or 1.74) and have Duravision Platinum coating (they don't call it "nano-coating"). They do follow the Zeiss tradition of being pricey though!! The lenses alone cost like a AF-S 105 2.8 (thankfully not like a 105 1.4!!!).
In any case, I thought interesting to see some other Zeiss product lines!
