Buyer fit
For distributors positioning a clear-base option within their blue-filter assortment. Evaluate neutrality, paired appearance and spectral performance independently, using the exact proposed product rather than a generic demonstration.
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.

Material-property references require confirmation against the exact substrate data sheet; they are not finished-lens acceptance results.
Lens design
A clear-base option is selected for its visual appearance as well as its specified filtering. The illustration shows a qualitative comparison only. Use actual lenses over the same neutral background to approve the appearance of the chosen program.
Application & selection
Retain the approved sample and its transmission evidence under the same SKU. A less yellow appearance should not be used to infer a particular blocking percentage, and a similar reflection color should not authorize a material substitution.

Procurement FAQ
No. Base appearance and filtering must be evaluated separately using the selected product's data.
The defined comparison covers 1.56, 1.60 and 1.67. Additional indices need a separate confirmed specification.
Compare identified pairs under consistent lighting and keep a retained master sample with the order specification.
