Hydration and SIB Material Technology
The lens uses SEED’s proprietary SIB (Zwitterionic) material, which contains both positive and negative ions to help repel protein deposits and oils, keeping the lens cleaner over the month. The packaging solution also includes natural alginic acid (derived from seaweed) to attract and hold moisture, helping the lens maintain stable 58% water content and reduce dryness.
Oxygen Transmissibility
The lens has an oxygen transmissibility of 30.0 × 10⁻⁹ (measured at -3.00D), which is sufficiently high to support daily wear and help minimise redness and irritation throughout the month.
UV Protection
The lens contains UV absorbers to help protect the eyes from harmful UV rays; however, this does not replace proper UV‑blocking eyewear (e.g., sunglasses).
Handling and Convenience Features
“OK” Marking: Each lens has an “OK” imprint to help users quickly identify the correct orientation before insertion, reducing handling time and errors.
Light Blue Tint: Makes the lens easier to see and handle during insertion and removal.
Japanese Quality Assurance: From material development to final packaging, the entire process is conducted in Japan under strict quality controls, with ISO13485 certification for medical devices.
