Buyer fit
For optical buyers evaluating a modest lower-zone support option alongside ordinary single-vision lenses. Confirm right/left design, fitting references and intended prescription range, and keep medical benefit claims separate from the geometric specification.
Start with representative samples, approve the agreed specification, then use it as the reference for trial and repeat orders.
Technical parameters
Final material, power matrix, coating, tolerances, tests, and availability are confirmed before quotation.

Lens design
The lower area supplies the specified support relative to the distance correction, with a gradual transition. The illustration shows the +0.75 D design reference without representing a measured power map or guaranteed symptom relief.
Application & selection
Qualified optical staff should review suitability, prescription and frame adjustment, then collect the required fitting information. Keep the order distinct from both a conventional single-vision lens and a full progressive prescription.
