Zwitterionic Material "SIB"
"SIB" stands for SEED Ionic Bond, and ensure biocompatibility. Every pair of SEED PURE series contact lenses is made from Original "SIB" material. It contains both positive and negative ions, resulting in electrical stability. This stability keeps on dust and impurities, while ensuring high water content.
High Oxygen Permeability
Regardless of high water content, SEED 1dayPure Multistage excels in morphological stability. Thus, the thickness of the lens centre is 0.07mm (-3.00D), which is the thinnest class among daily disposable high water content contact lenses.
Due to high water content and the thin lens design, the oxygen transmissibility becomes 42.9. This value is high enough to transmit adequate oxygen, which is sufficient for human eyes.
High Contamination Resistance
Although zwitterionic material "SIB" is ionic and has high water content, it has the advantage of keeping away the proteins, which cause contamination.
Containing UV Absorber
SEED 1dayPure Multistage contains UV absorber.
Contact lens with UV absorber significantly reduces absorption of UV rays.
High Moisture Retention
In addition to its strong ability to attract and retain moisture, the zwitterionic material SIB also has two types of moisturising ingredients, alginic acid and non-ionic surfactant. With the ability to retain moisture, it is highly recommended for wearers who experience dryness in their eyes during the evening.
