BalanceMax
Entry-level progressive with a soft design
Explore design and specificationsSoft Basic Progressive without personalisation and with three near-reference positions, for consideration in the entry-level range.
Application and design rationale
Entry-level class with three near options
Non-personalised Soft design with near-reference positions of 14, 16 or 18 mm. It differs from personalised models in individual calculations and design options.

Design mechanism and features
Balanced everyday use
BalanceMax is a Soft Basic progressive. Three NRP options of 14, 16 and 18 mm allow the power-transition path to be chosen for a standard frame.
Difference from MiniMax
Compared with MiniMax's fixed 12 mm NRP, BalanceMax's longer paths offer different power-distribution opportunities. Maximum addition is +4.00 D for BalanceMax and +3.50 D for MiniMax.
Standard order
BalanceMax has Personalization: No. PD, fitting height and frame dimensions still require recording; no personalisation does not mean no precise fitting. DuraTrace and Core Inset are mentioned.
Technologies in this design
- DuraTrace
- Ray-tracing calculations and optical-aberration optimisation in surface design.
- DuraBase
- Nominal-power calculations; also described as Nominal Power in the sources.
- Core Inset
- Standard automatic inset for near-zone positioning, as specified in the product table.
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.
Design-specific inputs
- Core Inset (0–4 mm): standard horizontal displacement of the reading focus according to distance prescription power and reading distance.
- Corridor Selection (14, 16, 18 mm): gentler corridors can reduce the power-change gradient and widen the intermediate corridor.
- Nominal Power Calculation: edging based on nominal lens power without dependence on individual pantoscopic, wrap or BVD fitting values.
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.
