In January 2024, our technical renovation project \u2014 an annual capacity of <strong>2.2 million pairs of eyeglasses<\/strong> \u2014 entered formal environmental impact assessment (EIA) review with the Ouhai District ecological environment authority in Wenzhou, a public, government-supervised step in our capacity upgrade program.<\/p><h2>What the Project Covers<\/h2><p>The renovation project is registered under <strong>Wenzhou Ouhai Dongtian Eyewear Manufacturing Co., Ltd.<\/strong> at our production site on Jingyu Road, Louqiao Street, Ouhai District \u2014 the heart of one of China&#8217;s five major eyewear manufacturing bases.<\/p><p>Technical renovation (&#8220;jigai&#8221;) projects like this one upgrade existing production rather than simply adding square meters: newer equipment, cleaner processes, better energy efficiency and higher output per line. The formal EIA filing covers the environmental review of those upgraded processes \u2014 emissions, waste handling and noise \u2014 under China&#8217;s Environmental Impact Assessment Law and Zhejiang&#8217;s construction project environmental regulations.<\/p><p>For buyers, the significance is straightforward: our capacity figures \u2014 <strong>PC 700K, TR90 200K, acetate 150K and metal 150K pairs per month<\/strong>, plus 6.5 million lenses per month from our in-house lens workshop \u2014 are backed by continuously upgraded, compliance-audited production, not aging equipment at the end of its life.<\/p><h2>Why Capacity Investment Matters in a Tariff-Driven Market<\/h2><p>Recent years have taught global buyers an uncomfortable lesson: supply shocks arrive faster than new suppliers can be qualified. When US tariff policy shifted sharply in 2025, many importers discovered that their backup options were either too small, too slow or too unproven to absorb displaced volume.<\/p><p>Our answer has been to invest on both sides of the risk equation:<\/p><ol><li><strong>In China<\/strong> \u2014 this 2.2 million pairs\/year renovation keeps our Wenzhou base modern, efficient and compliant, protecting the fast-turn, full-category OEM\/ODM programs that depend on mature supply chains.<\/li><li><strong>In Thailand<\/strong> \u2014 our 8,000 m\u00b2 second plant entered production in 2025 serving international brand customers, providing ASEAN-origin capacity for tariff-sensitive programs.
