ZWITTERIONIC MATERIAL “SIB”
"SIB" stands for SEED Ionic Bond, and ensures 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 out dust and impurities, while ensuring high water content.
Zwitterionic material, "SIB" is an original hybrid material of SEED. It has the advantages of both non ionic low water content lenses, which are highly resistant to deposits and stable to the environment, and high water content lenses, which allows for a high level of oxygen permeability.
LENS DESIGN
SEED's unique "Dynamic Prism Ballast" design constitutes three designs, namely, the "Upper Portion Slab-off", Prism Ballast Design and "Adjustable Parametric Design".
* Alginic Acid: Natural moisturising ingredient extracted from seaweed and kelp.
GOOD DEPOSIT RESISTANCE
Although zwitterionic material "SIB" is ionic and has high water content, it has the advantage of keeping away the proteins, which cause deposits.
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.
GOOD DEPOSIT RESISTANCE
Although zwitterionic material "SIB" is ionic and has high water content, it has the advantage of keeping away the proteins, which cause deposits.
CONVENTIONAL IONIC LENS
The negative ions in the material strongly repel each other, hence making the lens surface negatively charged. Therefore, it attracts the positively charged deposits, e.g. proteins.
ZWITTERIONIC MATERIAL “SIB”
There are equimolar amounts of positive and negative ions in the material. Thus, there is no deviation of charge on the lens surface. Therefore, it doesn’t attract positively charged deposits e.g. proteins.

Surface acting agent attracts moisture and prevents adhesion of deposits.
Natural moisturising ingredient extracted from seaweed and kelp.
It attracts moisture and keeps tears in the lens surface at thesame time.
