    30.05.2016

    Do Green is a bio-based high refractive index lens material using plant-derived material developed by Mitsui Chemicals. This lens monomer, called MR-16 (refractive index 1.60), is based on Mitsui’s new aliphatic isocyanate-derived biomass, STABiO PDI and has been certified as a biomass-derived product in both Japan and the United States.


    Mitsui Chemicals collaborated with the SWANS program of Yamamoto Kogaku Co., Ltd., which has a good track record in designing products for more comfortable sports performance, and Itoh Optical Industrial Co., Ltd., which has expertise in the manufacture of high-performance lenses, to develop Do Green™ sunglasses. The sunglasses use Mitsui Chemicals’ bio-based lens and frame material and have acquired biomass product certification in Japan.

    Mitsui Chemicals is a YOKOHAMA SUPPORTER and provides its support to the ITU World Triathlon Yokohama. Do Green sunglasses were presented to participants, judges, and staff members of the event.

    At the event’s Expo, Mitsui Chemicals displayed its Do Green sunglasses, its stamp magnifying glass for persons with low-vision and age-related vision problems and which has the world’s highest magnification power, its performance-driven prosthetics materials, and its braille tiles (silica) which are being used by Yokohama City, in addition to its other barrier-free solutions.
