SEED 1dayPure EDOF
The First Ever Japan-made EDOF Contact Lens
SEED 1dayPure EDOF is a daily disposable soft contact lens for presbyopia which is entirely made in Japan. Working jointly with Brien Holden Vision Institute, a world-renowned research institution, Extended Depth-of-Focus (EDOF) technology is adopted, providing good vision at all distances, while minimizing ghosting and haloes.
EDOF Lens Design that provides stable visual performance
Brien Holden Vision Institute※ and SEED have developed and commercialized an algorithm that unlocks the full potential of optical characteristics (lens performance) and visual properties (visual acuity for users). Applying this special algorithm to lens design, we have developed a unique EDOF lens that minimizes variability in visual performance at varying visual distances, the major limitation of conventional bifocal contact lenses. The EDOF lens also provides good perceived image quality under a broad range of conditions.
Brien Holden Vision Institute (BHVI) is a non-profit translational research, education and public health organization affiliated with the University of New South Wales in Sydney, Australia, developing new solutions for vision care, especially for myopia and other refractive errors. It is leading global professional education and advocacy efforts to address the myopia epidemic.
Three Lens Designs for Three Different Depth-of-Focus Ranges
To meet patient's extensive needs, three lens designs for three different depth-of-focus ranges are provided. Each lens design features extended depth of focus and provides the power distribution needed to minimize perceived image quality deterioration.
High Quality Manufacturing in Japan
SEED’s 1dayPure Series is daily disposable contact lens made entirely 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 seawood. It attracts moisture in eyes, and keeps tears on the surface of the lenses.
■Zwitterionic material "SIB"
SEED's original material "SIB" (SEED Inoic 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 Absorbers
Ultraviolet rays (UV) causing skin pigmentation such as spots, are said to be one of the causes of eye diseases such as cataracts.
SEED 1dayPure EDOF contains UV absorbers that shield your eyes from ultraviolet rays, protecting your eyes from harmful ultraviolet light and keeping your eyes healthy.
*Contact lenses with UV absorbers do not block 100% of UV light and are not substitutes for UV absorbing eyewear.
High Oxygen Permeability
The high moisture content and ultra-thin 0.07 mm* center design smoothly transmits adequate oxygen to your eyes.*(at -3.00D)
To help users distinguish between the inside and outside faces, 1 marker can be found on every lens to ensure the easy handling and safe uasge of SEED 1dayPure EDOF.
32Lenses in One box
SEED 1dayPure EDOF has 32 pieces of lenses in one box. Even with extra 2 pieces of lenses, SEED's packaging is just as compact as other boxes containing 30 pieces of lenses.
Use-friendly Design : Fingertip Closure Mechanism
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.
