Procurement FAQ
Questions buyers ask before sampling.
Is this a myopia-control lens?
No. It is a conventional single-vision lens with one correction zone. It does not use a defocus or other myopia-management design.
What does UV420 mean?
UV420 identifies the intended UV and blue-violet filtering program, but it does not define one universal blocking percentage. The required wavelength bands, transmission limits, and test method should be written into the order specification.
What does SHMC add?
SHMC combines a hard multi-coating stack with an easy-clean top layer. Reflection color, contact angle, abrasion resistance, and cleaning durability should be approved against samples or an agreed test.
Is the lens visibly blue?
The lens base is clear. Blue-green or violet color is mainly seen in the reflected coating light; residual color and wearer transmission should still be checked on samples.
Can it be used for reading prescriptions?
Yes, when supplied in an appropriate positive single-vision power. It provides one near correction zone and is different from bifocal or progressive lens designs.
Are all powers and diameters always in stock?
No. Availability varies by sphere, cylinder, surface design, diameter, and coating batch. Send the required matrix for confirmation before ordering.
