A lifestyle-family product with an Adaptive progressive design; personalisation, variable inset and pre-calibration are specified.
Application and design rationale
Progressive design considering the final form
SlimMax is Adaptive and differs from single-vision FlatMax. Pre-calibration and frame selection affect final thickness; no fixed thickness-reduction value is stated.

Design mechanism and features
A slim progressive, not a single-vision lens
Although marketed in Lifestyle, SlimMax is a premium Adaptive progressive. Its technology description lists DURA SIZE 2.0 alongside DuraCore AI, DuraMesh, DuraTrace and DuraAperture.
Corridor and addition
NRP is 12–18 mm and addition +0.75 to +4.50 D. The frame must retain the near zone at the selected length; the shortest corridor is not always the most appropriate.
Thickness optimisation
The document claims thickness reduction “up to 30%” without comparison conditions or reference samples. It is not a guaranteed result for every prescription; geometry optimisation depends on prescription, material and frame dimensions.
Difference from FlatMax
FlatMax is single vision aimed at thickness optimisation; SlimMax additionally transitions across distance, intermediate and near powers. They are not direct substitutes in addition or corridor terms.

DURA SIZE 2.0
The updated document uses this term for geometry and thickness optimisation. It has no separate website page; its application is explained in this product's mechanism section.
Measure before manufacture
Required parameters vary by design and must be recorded by a professional.
Monocular pupillary distance
For aligning the lens centre with each eye's visual axis.
Fitting height
Vertical pupil position relative to the frame in the position of wear.
Back vertex distance
One of the inputs describing the actual position of wear.
These are basic fitting parameters; additional inputs and the level of personalisation are specified for each model.
