Buyer fit
Built around a clear procurement decision.
Positioned for optical wholesalers, laboratories, and retail groups that need a step-up product above standard 1.56 blue-cut lenses, with a thinner 1.60 index and an aspheric design for mid- to higher-power prescription ranges.
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.

Procurement FAQ
Questions buyers ask before sampling.
What does ASP mean?
ASP means aspheric. The lens surface changes curvature from the center toward the edge, allowing a flatter profile than a comparable conventional spherical design and helping control off-axis optics.
How does 1.60 compare with 1.56?
For the same prescription and design conditions, 1.60 can reduce lens thickness. The actual difference depends on power, diameter, decentration, frame shape, center thickness, and edging requirements.
Does UV420 define an exact blue-light blocking percentage?
No. UV420 is a product specification name, not a universal transmission percentage. The required wavelength range, transmission target, and test method should be written into the approved order specification.
Is SHMC included in every quotation?
This page is positioned around the SHMC program, but the final coating stack, reflection color, hydrophobic performance, and durability requirement must be confirmed with samples and the quotation.
Are all three diameters available for every power?
No. Diameter availability normally changes with sphere, cylinder, base curve, and coating stock. Send the required power matrix so the suitable diameters can be confirmed.
Is 1.60 suitable for rimless frames?
Suitability depends on the exact substrate, impact requirement, lens thickness, drilling method, frame hardware, and local standard. State the frame construction so the material can be reviewed before ordering.
