Procurement FAQ
Questions buyers ask before sampling.
How dark will the lenses become?
Activated color depends on UV intensity, temperature, material, technology, and test conditions. Target performance should be approved with samples.
Are grey and brown both available?
Yes. Other colors may be available depending on technology and quantity.
Can photochromic be combined with progressive design?
Selected progressive and bifocal combinations can be discussed along with corridor, base curve, and power requirements.
What should we test in samples?
Review indoor residual color, activated shade, fade behavior, coating reflection, power accuracy, and consistency between lenses.
