Description
Discover the daily disposable contact lens for presbyopia that daily disposable contact lens users have long desired – SEED 1dayPure Multistage. With an optical design that is crafted to deliver “Natural Vision”, it enables single vision lens users to easily shift. It also offers the unique benefits of worry-free and comfortable use that daily disposable lenses are favoured for.
FEATURES
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 Multistage lenses are designed to give you optimal vision whatever your eyes are focusing on.
THE LENS DESIGN
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) |
ZWITTERIONIC MATERIAL “SIB”
“SIB” stands for SEED Ionic Bond, and ensure biocompatibility. Every pair of SEED PURE series contact lenses is made from Original “SIB” material. It contains both positive and negative ions, resulting in electrical stability. This stability keeps on dust and impurities, while ensuring high water content.
HIGH OXYGEN PERMEABILITY
Regardless of high water content, SEED 1dayPure Multistage excels in morphological stability. Thus, the thickness of the lens centre is 0.07mm (-3.00D), which is the thinnest class among daily disposable high water content contact lenses.
Due to high water content and the thin lens design, the oxygen transmissibility becomes 42.9. This value is high enough to transmit adequate oxygen, which is sufficient for human eyes.
HIGH CONTAMINATION RESISTANCE
Although zwitterionic material “SIB” is ionic and has high water content, it has the advantage of keeping away the proteins, which cause contamination.
CONTAINING UV ABSORBER
SEED 1dayPure Multistage contains UV absorber.
Contact lens with UV absorber significantly reduces absorption of UV rays.
HIGH MOISTURE RETENTION
In addition to its strong ability to attract and retain moisture, the zwitterionic material SIB also has two types of moisturising ingredients, alginic acid and non-ionic surfactant. With the ability to retain moisture, it is highly recommended for wearers who experience dryness in their eyes during the evening.
