Procurement FAQ
Questions buyers ask before sampling.
Is this a myopia-control lens?
No. This page describes a conventional single-vision blue-cut lens assortment for children's and youth eyewear. It does not describe a defocus or other myopia-management design.
Does blue cut prevent myopia?
No such claim is made. Blue-filter performance and prescription correction are separate from evidence-based myopia-management strategies, which require an appropriate lens design and professional clinical guidance.
Is the lens automatically impact resistant because it is for children?
No. Impact performance depends on the exact substrate, thickness, processing, frame construction, and test standard. State the destination-market requirement so the correct material and test can be quoted.
What does UV420 mean on this product?
It identifies the intended UV and blue-violet filtering program, but it does not define one universal transmission curve. The wavelength bands, limits, and test method must be confirmed in the order specification.
How should we build the youth power matrix?
Send historical sales by sphere and cylinder, common frame eye sizes, target inventory depth, and replenishment frequency. Diameter and stock coverage can then be planned around actual demand.
Can the blue reflection color be approved before ordering?
Yes. Samples should be checked under consistent lighting for reflection color, residual lens color, pair matching, coating cosmetics, and transmission requirements.
