シューユウ List of Products and Services

At Shooyu Co., Ltd., we plan, design, engineer, and manufacture all kinds of eyewear, from sunglasses to general vision correction glasses. We specialize in glass polarized lenses and photochromic lenses, which are much harder and do not deform compared to plastic lenses, requiring high quality and precision in the eyeglass frames that hold them. With the technology we have accumulated over many years, we currently manufacture high-end sunglasses for many well-known overseas brands. We also process metal frames using laser welding machines. Furthermore, we perform surface treatments regardless of the material of the eyeglass frames. In addition to painting metal and plastic frames, we have unique painting techniques such as soft-touch processing that creates a distinctive texture, leather-like coating, and wood grain coating. **Features** - Development, design, and engineering processes utilizing 3D technology - Frame materials handled: metal frames and resin frames - Products shipped have passed inspections by the Japan Optical Association and CE inspections - OEM services available For more details, please contact us or download our catalog.
