I have just received my lenses, but I noticed that the color is not exactly the same as what I have been purchased before. What makes the lens color become darker or lighter than before?

We won't change the colors of our contact lens. There is no intentional change for the color opacity from year to year but it can be that the production of one production lot varies slightly from another production lot under very specific conditions, such as temperature and humidity. But these variations are always within the quality controlled ISO standards.

AI-Powered supplier vetting

SummaryThe supplier is a combined company with manufacturing, quality-control, R&D, export, and service capabilities. It reports nine quality inspectors, multiple production and inspection facilities, flexible customization, OEM and ODM services, and in-stock capacity. However, it lacks an effective manufacturing-capacity contract with related subcontractors, overseas agents, branches, warehouses, showrooms, and offline trade-show experience. Quality assurance is reported, but corrective-action and complaint-handling procedures lack written records. R&D partnerships and customization are stated, while no new products were introduced in the past year and no SDK is available. Financial-period and cash-flow references are provided, but the slices do not establish financial strength. Customer-case evidence is limited to OEM service for known brands and own-brand quality-control information.

Supplier typeThe supplier is explicitly identified as a combined company and offers information covering manufacturing, export trade, service, quality control, R&D, and sustainability. This indicates a multifunctional supplier structure rather than a narrowly defined service provider.

After-Sales capabilityThe supplier has in-stock service capacity and states average peak- and off-season lead times within 15 working days. However, it has no overseas agents or branches, overseas warehouse, showroom, or written procedures or records for complaint handling and corrective and preventive actions, limiting evidence of a formal after-sales system.

Production capacityThe supplier lists multiple production, printing, packing, sterilization, inspection, and testing facilities, employs nine quality assurance and quality-control inspectors, reports in-stock capacity, and states lead times within 15 working days. However, it also reports no valid manufacturing-capacity contract with related subcontractors, creating a documented weakness in capacity governance.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides ODM services. These repeated, specific capabilities support a strong customization assessment.
