Lens Design


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.

Lens Marking


“PA” mark is printed to help users distinguish between the inside and outside faces of the lens. The guide mark makes it easy to measure rotation for accurate fitting.

32 Lenses in One box


SEED 1dayPure moisture for Astigmatism has 32 pieces of lenses in one box. Even with the extra 2 pieces of lenses, SEED’s packaging is just as compact as other boxes containing 30 pieces of lenses.

User Friendly Design


For ease of usage, SEED has introduced the following designs for the convenience of its patients. Our Cross Unit Cases allow capsules for the left and right lenses to be joined together for easier packaging.


The wearer can open the package easily and close it at the touch of a finger. This eliminates the need for hand contact and is a more hygienic way of handling the box.

High Quality Manufacturing in Japan


All the manufacturing processes of SEED Pure series are strictly managed at SEED Kounosu laboratory. Great care is taken in producing each pair of SEED contact lenses at the manufacturing plant in order to ensure the utmost safety of human eyes. SEED takes its environmental responsibility seriously and ensures its facilities are eco-friendly.

Furthermore, using two-dimensional code and ID tag, we are implementing integrated management of production and distribution. It also enables all of the lenses to be traceable.

In addition, we have obtained the certification of ISO13485, which is the international standard of quality management systems for medical devices. This has further strengthened our quality control system.
