Features
Lens Design
DYNAMIC PRISM BALLAST
The thickness of the lens and the entire lens design is controlled according to the various parameters.Its “Dynamic Prism Ballast” design provides good lens stability, hence making fitting simple and easy.
What is “Dynamic Prism Ballast”?
“Dynamic Prism Ballast” is a design constituting three designs, namely, the “Upper Portion Slab-off” Prism Ballast Design and “Adjustable Parametric Design.”
Good Vision Correction
To maximize the effect of astigmatism correction, we adopt a technique known as front toric technique.
Ease of Fit
From the combination of the lens material, lens design and natural moisturizing agent included, moisture is retained and we hope to provide wearers a more comfortable fit.
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
“2PA” & “|” 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 Astigmatism moisture.
