Enhanced water retention is possible by using alginic acid as a natural moisturizing agent and zwitterionic material “SIB.” Keeping the conventional characteristics of Japanese quality, UV absorber, and contamination resistance, the series now also offers a long-lasting moisture retention.

Features
High Moisture Retention

■Natural Polymer “Alginic Acid”
Contact lens storage solution is infused with alginic acid which is a natural moisturizing agent extracted from seaweed. It attracts moisture in eyes, and keeps tears on the surface of the lenses.
■Zwitterionic material “SIB”
SEED’s original material “SIB” (SEED Ionic Bond) which contains both positive and negative ions resulting in electrical stability. This stability ensures high water content while keeping out dust and impurities.
High Contamination Resistance

Containing both positive and negative ionic properties, the zwitterionic material “SIB” has superior biocompatibility and repels contamination while retaining materials. Because of the feature of deposit resistance, comfortable wearability can last for two weeks.
Len Marking

LENS MARKS
“2Pure2” & “860” mark is printed to help users distinguish between the inside and outside faces of the lens.
CLEAR INSIDE-OUT DISTINCTION
To help users distinguish between the inside and outside faces, 2 marks can be found on every lens to ensure the easy handling and safe usage of SEED 2weekPure UP moisture.
