Zenn or Zenn AI?
Both are premium. Both carry Edge-to-Edge Compensation, Smart Add, and the premium coatings. Both are the only place 1.74 is made. The difference is one question: is one excellent design enough, or does your day justify a design chosen for it?
Which one is for you
Zenn
Choose it when
Your day is varied and no single visual task dominates.
Its limit
One design for every wearer: if your working day is unusually near-dominated or unusually demanding, the design choice lives in Zenn AI, not here.
Zenn AI
Choose it when
Your work is visually specific — long near-focus, constant near-to-mid movement, or precision under pressure — or you have struggled to adapt to a progressive before.
Its limit
It is only as good as the description of your day: choose the wrong design and a more expensive lens performs worse than a cheaper one.
The full reasoningRead less
Zenn is one uniform progressive design, calculated completely — point-by-point compensation from center to edge. For a wearer with a balanced day — some reading, some screens, some distance — it is genuinely excellent, and nothing about it is a compromise.
Zenn AI starts from a different premise: that a pharmacist reading labels all day and a trader watching six monitors should not receive the same geometry. Its three designs place the clear zones where your working day actually needs them — and on single vision, AI selection chooses the configuration that fits your profile.
Choose Zenn when your day is varied and no single visual task dominates. Choose Zenn AI when your work is visually specific — long near-focus, constant near-to-mid movement, or precision under pressure — or when you have struggled to adapt to a progressive before. The more specific your day, the more the AI design returns.
