SEED 1dayPure® Multistage

The first disposable bifocal soft contact lens to be made in Japan, SEED 1dayPure moisture Bifocal offers a unique optical design that is crafted to deliver "Natural Vision". Crafted for worry-free and comfortable wear, it enables single-focus lens users to easily make the switch to bifocals.


As Good As Your Own Eyes

Using our original zwitterionic material SIB (SEED Ionic Bond), and Alginic Acid as a natural moisturising agent, SEED 1dayPure Multistage lenses retain more water to keep your eyes moist and comfortable for extended hours!

SEED 1dayPure moisture Bifocal lenses are designed to give you optimal vision whatever your eyes are focusing on.


To provide users a smooth shift from single vision lens, we have carefully thought of changing the addition power and the optical design for Type A and B, hence minimizing discomfort and maximizing visual performance. We also adopted the "Adjustable Parametric Design" found in "SEED 1dayPure UP". By controlling the thickness and curvature for each power, and thinning the bevel design, users can experience greater comfort while wearing it..

Type A

This design provides natural vision, just like single vision lenses. (Additional power +0.75D)

Type B

This design emphasises and defines the difference between near and distant vision. (Additional power +1.50D)
