Recommendation
The recommendation of Goyenchem-BL475 is suggested to 0.5~5% by GYC technical department.
The addition of film thickness is proportional to the blue light absorption rate. The addition can be adjusted by customer’s formula condition and film thickness.
| Condition | Suggestion |
| Film thickness 250μm | 0.5%-1% |
| Film thickness under 50μm | 2%-5% |
| General plastic material and lens thickness 1.5-2mm | 0.5%-0.8% |
