FEATURES


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.
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.

Schematic Diagram of Deposits Resistance
The cross section of the lens
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.


CONTAINING UV ABSORBER"

SEED 1dayPure moisture for Astigmatism 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.

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 the same time.
