Buyer fit

Built around a clear procurement decision.

For distributors and laboratories sourcing conventional progressive ranges. Keep corridor selection, wearer fitting height, addition and frame trace as separate inputs, and use the design-specific fitting chart.

Start with representative samples, approve the agreed specification, then use it as the reference for trial and repeat orders.

Technical parameters

Typical supply configuration.

Final material, power matrix, coating, tolerances, tests, and availability are confirmed before quotation.

Lens design

Understand the three viewing regions

A progressive design changes optical power gradually from distance through intermediate to near. The illustration identifies the general regions; it is not a measured power map of the ordered lens or a promise of identical fields for all wearers.

Application & selection

Approve fitting before production

Provide the prescription, addition, frame trace and required wearer measurements. The optical team should verify the selected design, markings and cutout. Review the fit again if the frame or corridor option changes.

Procurement FAQ

Questions buyers ask before sampling.

Are corridor length and fitting height the same?

No. Use the selected design's instructions to identify each measurement.

Can every progressive design fit a shallow frame?

No. Have optical staff assess the actual frame and required fitting measurements.

Is adaptation guaranteed?

No universal adaptation promise is made. Design selection, prescription, fitting and individual needs require professional review.
