Quality control is the backbone of contact lens manufacturing. At MIOMI Optical, we follow strict protocols to ensure every pair of lenses meets international safety standards.
Our Quality Control Process
1. Raw Material Inspection
All raw materials undergo rigorous testing before production. We verify purity, moisture content, and biocompatibility.
2. In-Process Quality Checks
During production, lenses are inspected at multiple stages for diameter, base curve, center thickness, and color accuracy.
3. Final Product Testing
Every batch undergoes final inspection including sterility testing, endotoxin testing, and packaging integrity checks.
