Quality Control Philosophy

Eyewear quality depends on the control of materials, processes, and assembly.

Rather than relying solely on final inspection, we apply quality control throughout the production cycle to reduce variation and prevent issues before they occur.

Incoming Quality Control (IQC)

Material Verification Before Production

All key materials are inspected before entering production.

Scope of Inspection

  • Lens materials and coatings
  • Frame materials and components、
  • Hinges, screws, and metal parts
  • Packaging materials

Inspection Focus

  • Appearance and surface condition
  • Dimensional accuracy
  • Color and material consistency
  • Supplier conformity

Only approved materials are released to production.

In-Process Quality Control (IPQC)

Process-Level Control During Manufacturing

Quality checks are conducted at defined checkpoints during frame production, lens processing, and assembly.

Control Points

  • Frame forming and finishing
  • Lens coating and tinting
  • Lens edging and fitting
  • Assembly alignment

Final Quality Inspection (FQC)

Inspection Before Packaging and Shipment

Each finished eyewear product is inspected prior to packaging.

Inspection Criteria

  • Visual appearance and finish
  • Lens and frame alignment
  • Functional performance
  • Logo placement and branding accuracy

Products that do not meet approved specifications are removed from shipment.

Assembly Quality Control

Fit, Alignment and Stability

Assembly quality is critical to final product performance.

Key Checks

  • Lens fit and seating
  • Frame symmetry
  • Mechanical stability
  • Hinge function and tension

Assembly procedures are standardized to ensure consistent results across batches.

Traceability & Batch Control

Production Record Management

We maintain production records for key materials and processes.

Traceability Includes

  • Material batch identification
  • Production and assembly records
  • Inspection results

This system supports controlled production and post-delivery follow-up when required.

Continuous Improvement

Quality management is an ongoing process.

  • Feedback from production and inspection is reviewed
  • Process adjustments are implemented where necessary
  • Preventive measures are prioritized over corrective actions

Our goal is stable, repeatable quality over time.

Compliance & Market Requirements

We support manufacturing in line with common market requirements for eyewear products.

Where required, we can assist with documentation related to:

  • EU and US market standards
  • Material and safety compliance

Specific compliance requirements can be reviewed during project development.

Quality as a Partnership

Quality control is most effective when expectations are clearly defined.

We work closely with our clients to:

  • Confirm specifications before production
  • Align quality standards
  • Support long-term product consistency
