Mitsui Chemicals, Inc. (Tokyo) announced plans to boost production capacity for its world-leading MR™ series of high refractive-index lens material.
MR™ by Mitsui Chemicals is the de facto standard in high-refractive-index lens materials. As a leader in revolutionizing eyewear products by manufacturing premium lens materials, Mitsui Chemicals supports lens manufacturers worldwide across the value chain through the development of top tier lens materials and high-quality coating materials.
High-refractive-index ophthalmic lenses are high-performance products that enable thinner, lighter designs. High-refractive-index ophthalmic lenses are forecasted for long term growth due to the continued growth of the world population and the increasing myopia population. The demand for this segment of value‑enhanced offerings continues to grow particularly in Asia and North America.
In response to rising market demand, Mitsui Chemicals will expand its MR™ production capabilities at Omuta Works through the construction of a new plant, with commercial operations planned for the first half of 2029.
This expansion covers multiple MR™ brand portfolio. This facility expansion will comprehensively increase supply capacity across a wide production lineup and further strengthen the supply system for global markets.
