Buyer fit
For distributors comparing a surface-applied photochromic route across several materials. Approval should cover the finished coating stack, baseline appearance, color uniformity, activation and the intended laboratory handling.
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 |
|---|---|
| Photochromic route | Spin-coated surface layer |
| Index program | 1.56 / 1.57 / 1.60–1.61 / 1.67 / 1.74 |
| Base options | Clear base / blue cut |
| Color choices | Grey / brown; pink, blue, orange, purple, yellow and green by inquiry |
| UV options | UV400 / UV420 requirements confirmed by evidence |
| Specialist variants | In-car or enhanced abrasion-resistance programs quoted separately |
| Substrate | Exact resin identity confirmed; MR-8 is a 1.60 material |
| Performance | Product-specific activation, fading and coating criteria |
| Index program | Diameter references | Material / process review |
|---|---|---|
| 1.56 | 72 / 65 mm | Substrate and coating compatibility |
| 1.57 | 72 mm | Exact material specification |
| 1.60 / 1.61 | 75 / 70 / 65 mm | Confirm index and trade-name identity |
| 1.67 | 75 / 70 / 65 mm | High-index coating route |
| 1.74 | 75 / 70 / 65 mm | High-index coating route |
Diameter availability remains dependent on the confirmed power matrix and product variant.
Lens design
The spin-coated route places the photochromic function in a surface layer. This qualitative layer drawing explains the construction; actual chemistry, thickness and protective treatments follow the approved product specification.
Application & selection
An in-car option and an abrasion-resistance upgrade need their own identification and evidence. Compare them with the standard program under defined conditions, and do not carry one variant's claims onto every spin-coated lens.

Procurement FAQ
No. The photochromic construction route differs; compare the finished specifications and evidence for each program.
No. It is a separately identified inquiry requiring documented performance and intended-use review.
Color uniformity should be assessed using representative samples and an agreed method rather than assumed from the process name.
