Our most individualized lens, and every Zenn AI lens is anti-reflective — NOX, CLEAR ONE, GLIT or DRIVE CLEAR. It works differently depending on what you need:
- Progressive
- three AI designs, matched to how you actually use your eyes. Smoother adaptation and more stable vision than a design that has to suit everyone — because the configuration was chosen for your profile, not averaged across every wearer.
- Single vision
- AI selection. The single-vision configuration chosen for your profile, from thousands evaluated.
The design is the product
At every other rung the design is settled before you walk in. Here it is chosen — matched to how your own day divides between close work, screens, and distance. That choice is what the extra buys, which is why this is the tier where describing your day matters more than reading your prescription.
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. This is the tier where the optician's judgment matters most, and where guessing costs the most.
Match the occupation to the closest profile — not the age, not the prescription power. A first-time progressive wearer in a demanding visual role still needs Zenn Life or One Max. Comfort is the baseline every design delivers; what separates them is where the clear zones sit and how wide they are.

In depth
Edge-to-Edge Compensation corrects the optics at many points across the whole surface, so the prescription you receive well off-center stays close to the prescription at the center. Every Zenn AI design carries it.
Progressive — AI design Rather than one design that must serve every wearer adequately, there are three designs, each optimized for a distinct pattern of visual behavior. A progressive lens is always a compromise between the width of the distance zone, the width of the reading zone, and the softness of the blur either side of the corridor; you cannot widen one without narrowing another. What differs between Zenn Neo, Zenn Life and One Max is where that compromise is spent — and spending it in the right place for one person's working day is what makes the lens feel made for that day rather than averaged across everyone.
Single vision — AI selection Your visual profile — prescription, how you use your eyes, your frame — decides which single-vision configuration is chosen from the supplier's design library for the order. The same selection as the progressive, applied to one distance.
