SEED 2weekPure moisture for Astigmatism
A sharper view for astigmatic eyes.
SEED’s original lens design adopted in this bi-weekly contact lens for Astigmatism offers good vision. A natural moisturizing ingredient and zwitterionic material “SIB” provide comfortable wearability and a fit.
While ensuring Comfortable Wearability, the front toric design and the dynamic prism ballast reduces lens rotation, which maintains enhanced astigmatism correction.
High Quality Manufacturing in Japan
The entire process of manufacturing, from development of lens material to commercial production, takes place in Japan. To ensure the quality of each individual lens, each lens is carefully produced under strict quality control and inspection system for your safe use.
■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.
Containing UV Absorber
Ultraviolet rays (UV) causing skin pigmentation such as spots, are said to be one of the causes of eye diseases such as cataracts.
SEED’s 2weekPure Series contains an UV absorber that shields your eyes from ultraviolet rays, protecting them from harmful ultraviolet light and helps keep them healthy.
*Contact lenses with an UV absorber do not block 100% of UV light and are not substitutes for UV absorbing eyewear.
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.
To help users distinguish between the inside and outside faces, lens marking can be found on every lens to ensure the easy handling and safe usage of lens.
