Design mechanism and features
Single vision with thickness optimisation
FlatMax is marketed within Lifestyle but is optically single vision, without progressive corridor or addition. The document mentions digital lenticularisation and DURA SIZE 2.0 for thickness optimisation.
DuraTrace and frame geometry
DuraTrace is described as managing oblique-gaze errors and personalising to frame angles. Boxing dimensions and position-of-wear measurements provide design and pre-calibration inputs.
Interpreting thickness reduction
The text's “up to 30%” is a comparative claim without stated test conditions or reference lens. It does not guarantee thickness/weight reduction for every prescription; frame, power and material affect the result.
Technologies in this design
- DuraTrace
- Ray-tracing calculations and optical-aberration optimisation in surface design.
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 PD
- Each eye's pupillary distance is recorded separately to align horizontal lens positioning with the visual axis.
- Fitting Height
- Fitting height is recorded on the adjusted frame in the natural position of wear; the required near zone must also fit within the frame.
- BVD
- Distance from the rear lens surface to the corneal apex; relevant to power-compensation calculations in personalised models.
- Pantoscopic Angle
- The frame's vertical tilt in the position of wear must be measured; example values are not substitutes for measurement.
- Wrap Angle
- The horizontal curvature of the frame relative to the face, describing lens positioning.
- Box A
- Horizontal width of the frame opening in the boxing system.
- Box B
- Vertical height of the frame opening in the boxing system.
- DBL
- Distance between the two lens boxes at the frame bridge.
- ED
- Effective diameter: twice the greatest distance from the boxing centre to the lens-shape edge, used for blank selection and edging calculations.
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.
