Functional Lenses · CO-HC
An enhanced hard-coat program for buyers specifying abrasion resistance alongside anti-reflection and easy-clean finishes. Select the substrate, reflection color and acceptance method as one finished-lens specification.

Buyer fit
For distributors developing a coating upgrade with documented acceptance criteria. Compare finished samples using the same test method, conditioning and endpoint, and keep material and coating variants separately identified.
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.
Updated
| Parameter | Configuration |
|---|---|
| Index references | 1.56 / 1.61 / 1.67 / 1.74 |
| Coating program | Enhanced hard coat with compatible AR and topcoat |
| Reflection options | Light blue / light green |
| Diameter | 65–75 mm depending on index and power |
| UV requirement | Defined separately from abrasion resistance |
| Acceptance | Agreed test method and finished-product evidence |
| Index | Diameter options | Surface finish |
|---|---|---|
| 1.56 | 72 / 65 mm | Light blue / light green |
| 1.61 | 75 / 70 / 65 mm | Light blue / light green |
| 1.67 | 75 / 70 / 65 mm | Light blue / light green |
| 1.74 | 75 / 70 mm | Light blue / light green |
Power, coating and diameter combinations require quotation confirmation. A hard coat does not make a lens scratch-proof.
Lens design
The substrate, hard coat, anti-reflection layers and topcoat serve different roles. This schematic explains their arrangement; it does not specify production thickness or prove a measured abrasion result.
Application & selection
Request finished-product evidence tied to the selected material and coating. Include compatible cleaning and handling instructions with private-label packaging so the surface can be maintained correctly.

Procurement FAQ
No. Hard coatings improve the specified surface properties but can still be damaged by abrasive handling.
No. Reflection appearance and abrasion performance are separate specifications.
Only when the evidence explicitly covers those substrate and coating combinations. Confirm the scope of the report.
