What our ISO 9001 lens quality inspection covers

  • Incoming material verification: lens substrate, coatings and raw components are checked to ISO 9001 traceability standards.
  • Optical measurement: power, cylinder, prism and centration are measured with high-precision instruments to meet tolerance limits.
  • Surface and coating checks: AR, hardcoat and polarization are inspected for adhesion, uniformity and scratch resistance.
  • Visual and cosmetic inspection: edge finish, polish and frame fit are evaluated to ensure consistent appearance.
  • Final functional test: impact resistance and anti-fog tests for sports goggles and safety eyewear when required.
