TALEX Co., Ltd.

TALEX is a Japanese eyewear brand specializing in polarizing lenses and sunglasses, operated by TALEX Co., Ltd. (株式会社タレックス), headquartered in Osaka. Founded in May 1938, the company has built its reputation on a proprietary polarizing filter technology it markets as the "Zakkou-Cut Filter" (雑光®カットフィルター), a registered trademark (No. 4884270). The brand positions its lenses as "an air purifier for light" — rather than blocking all light, they are designed to remove only the harmful components of light, such as ultraviolet rays and reflected glare, which the company collectively calls "zakkou" (雑光®). TALEX offers a lineup of 19 lens types and sells both lenses and finished eyewear. Its product range includes the TALEX ORIGINAL SUNGLASS "Performance" frame line, the OZNIS sunglasses brand built around TALEX lens performance, and various collaboration models. The company organizes its offerings by use scene, including driving, beauty and health, outdoor, work, relaxation, night driving, daily sports, golf, winter sports, fishing, climbing, and drone operation. This scene-based segmentation reflects the brand's positioning as a functional, performance-oriented eyewear maker rather than a fashion-first label. Manufacturing is a central part of the TALEX identity. The company states that its Zakkou-Cut Filter is produced entirely in-house, from manufacturing to final finishing, and that more than 60 percent of the process is handmade. This craftsmanship is presented as essential to achieving the lens's optical performance, polarization efficiency, and filter adhesion. TALEX emphasizes three commitments: high polarization (zakkou-cut) rate achieved through iodine-based materials, world-class polarizing filter bonding technology, and prevention of the "red leakage" phenomenon by cutting over 99 percent of visible red light through iodine dyeing. Beyond consumer eyewear, TALEX has found institutional adoption in safety and professional contexts. Its lenses and protective eyewear have been introduced by organizations such as Shuto Expressway Patrol (首都高パトロール株式会社), which began full-scale adoption of protective sunglasses for approximately 400 patrol members in March 2023, and Hiroshima Electric Railway (広島電鉄株式会社), which adopted protective sunglasses for about 250 drivers across its lines. West Japan Railway Company (JR西日本) also adopted TALEX protective eyewear for conventional-line train drivers across all areas, with wearing beginning in late March 2020. These case studies underline the brand's emphasis on visual clarity, glare reduction, and fatigue reduction for professionals who depend on their eyesight. The company is led by representative Shinzo Tamura (田村 真三). Its headquarters and Tajima office are located in Ikuno-ku, Osaka, with a second Imakawa office in Higashisumiyoshi-ku, Osaka. TALEX also operates a directly managed PROSHOP & SHOWROOM and an online store, and it maintains a network of authorized pro shops across Japan. The brand remains privately held and active, with its official website serving as the primary channel for product information, lens lineups, and adoption case studies.

TALEX Co., Ltd. was founded on May 1, 1938, in Osaka, Japan. From its early years, the company focused on optical technology, and its lens development has continued since that founding date. The company states that since 1938 it has repeatedly improved and refined its proprietary Zakkou-Cut Filter (雑光®カットフィルター), a polarizing filter technology designed to remove harmful light components rather than simply block light. This long-term accumulation of technical know-how is central to the brand's identity. Over the decades, TALEX developed a manufacturing approach that sets it apart from mass-production methods. The company emphasizes that its lenses cannot be produced by fast mold-forming or press-processing mass-production techniques; instead, more than 60 percent of the process is handmade. This craftsmanship is presented as necessary to achieve the optical quality, polarization performance, and filter adhesion that the brand claims. The Zakkou-Cut Filter is manufactured and finished entirely in the company's own factory, a point TALEX highlights as proof of its integrated production capability. The brand's technology centers on three commitments. First, high polarization (zakkou-cut) rate: TALEX uses iodine-based materials in its proprietary filter to maintain high glare-cutting performance even in lighter lens tints. Second, world-class polarizing filter bonding technology: the company cites its technical accumulation since 1938 and its handmade process as key to maintaining adhesion performance. Third, prevention of the "red leakage" phenomenon: polycarbonate polarizing lenses can transmit visible red light, causing red flickering on water surfaces and contributing to eye fatigue; TALEX uses iodine dyeing to cut over 99 percent of visible red light, which it says eliminates red leakage entirely. TALEX also develops its own lens materials to maximize the performance of its polarizing filter. The company aims for lenses that cause no headaches or dizziness even when worn for long periods, and it describes the 0.03 mm polarizing filter sandwiched between lens layers as requiring ultimate handmade craftsmanship for proper adhesion. This combination of polarization, optical performance, and adhesion performance is presented as a world-class manufacturing achievement. In recent years, TALEX has expanded its presence in professional and institutional safety applications. West Japan Railway Company (JR西日本) conducted trials of protective eyewear for train drivers starting in September 2019, and after good results, expanded adoption to conventional-line drivers across all areas, with wearing beginning in late March 2020; the TALEX TrueView lens was selected, and the company's Original Over Glass and Clip-On Sunglass models were used. Shuto Expressway Patrol began trial introduction of protective sunglasses in August 2022 and, following verification of wearing effects and safety, became the first traffic management company nationwide to fully adopt them for approximately 400 patrol members from March 2023. Hiroshima Electric Railway adopted protective sunglasses for about 250 drivers across all lines to improve its safety environment. These adoptions reflect the brand's growing role in occupational eye protection. Today, TALEX remains a privately held Japanese company headquartered in Osaka, led by representative Shinzo Tamura. It sells through its online store, a directly managed PROSHOP & SHOWROOM, and a nationwide network of authorized pro shops. Its product lineup spans 19 lens types and multiple frame brands, organized by use scene from driving and fishing to golf, winter sports, and drone operation.
