by an Ophthalmologist and an Engineering 10x Opera for Live Concerts and Sports High Magnification Japanese Ruxis [Developed Doctor] Binoculars,

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ✅【365-Day Japanese Manufacturer's Warranty】A one-year domestic manufacturer's warranty is included. In the event of a malfunction or initial defect, we will promptly replace the product. ✅【30-Day Return Guarantee】We accept returns for 30 days after purchase, even for reasons such as the product not matching your expectations. *You will need your order number to receive warranty service. ✅ [Developed by an Ophthalmologist and an Engineering Doctor] Dr. Hiroko Kakizaki, a practicing ophthalmologist (13 years of clinical experience), and Dr. Kazuhiro Matsui, a graduate of the University of Tokyo and holder of an engineering doctorate (11 years of development experience), jointly developed these popular binoculars. They combine the knowledge of modern medicine and cutting-edge optics to achieve "amazing clarity." ✅【Advanced Optical Lenses / Fully Multi-Coated】Equipped with optical glass lenses from the world's leading manufacturer. A full multi-coating with 9 layers, polished to the nano-level, dramatically improves the "brightness" of the field of view. ✅【High-Grade BaK4 Prism】To maximize lens performance, a high-grade BaK4 prism is standard equipment. The Porro prism system provides sharp and highly clear images from edge to edge. ✅【High Magnification 10x x Wide 65-Degree Field of View】Recommended for large venues such as domes, arenas, and stadiums. The high-magnification zoom and wide field of view allow you to see the faces on stage clearly and in great detail even from far away seats, enhancing the immersive experience of live performances. It also works well as opera glasses, making it perfect for supporting your favorite idols. ✅【Ultra-lightweight 140g / Palm-sized】By thoroughly eliminating unnecessary elements from the main body structure, we have achieved an ultra-lightweight 140g while maintaining ease of viewing!

Its stylish body, which is easy to hold with one hand, is popular and is well-received by women and children. ✅【Reduces camera shake】Includes an eye cup for camera shake stabilization that is designed to fit the bone structure of Japanese people. By firmly fixing it to the brow bone and cheekbone, it provides image stabilization. ✅【Trusted Japanese Brand】Planned and developed by a Japanese company, and manufactured in a specialized factory with a proven track record of transactions with major global optical manufacturers. Under a rigorous double-inspection system, we carefully deliver high-quality binoculars to each and every customer. ✅【Complete 7-Piece Set】The package includes the following seven items: 1) Binoculars, 2) Soft storage case, 3) Lens cleaning cloth, 4) Eyecups, 5) Neck strap, 6) Hand strap, 7) Japanese instruction manual and warranty. ■ "Amazing Visibility and Brightness" Pursued by an Ophthalmologist and a University of Tokyo Graduate with a PhD in Engineering Ruxis 10x binoculars are high-performance opera glasses specifically designed for live performances, jointly developed by Dr. Hiroko Kakizaki, a practicing ophthalmologist (13 years of clinical experience), and Dr. Kazuhiro Matsui, a University of Tokyo graduate with a PhD in Engineering (11 years of development experience). In dimly lit domes or theaters, it can be difficult to see the expressions of your favorite performers from the back seats, and ordinary binoculars often cause eye strain due to the darkness of the field of view and hand tremors. This product combines knowledge of visual function with cutting-edge optical simulation to pursue "ultimate visibility" that displays distant emotions with high clarity. Equipped with distortion-free optical glass lenses and high-grade BaK4 prisms from a world-leading manufacturer, it delivers a bright and clear field of view to the very edges. ■ Optical design to capture your favorite idol's expressions from the back seats of domes and arenas This product was developed for those who want to clearly capture their favorite idol's expressions, gaze, and even the delicate movements of their fingertips, even from the far stands or upper seats at large arena venues such as Tokyo Dome. With a high magnification of 10x and a wide field of view of 65 degrees, it significantly improves brightness and field of view compared to typical compact binoculars. Even when moving around the stage, you won't lose sight of your favorite performer, seamlessly following the entire stage and their subtle expressions. Furthermore, the eyepiece features a foldable eyecup that ensures a clear view without vignetting (cropping) even when wearing glasses. Both those with and without glasses can enjoy comfortable viewing. ■ Advanced optical specifications created by high-grade BaK4 prisms and 9-layer FMC on all lenses The lenses are made of optical glass precisely polished to nano-precision, and all lens and prism transmission surfaces are treated with ultra-precise 9-layer multi-layer film deposition processing, "Full Multi-Coating (FMC)". This minimizes light scattering and overexposure (flare and ghosting), creating a breathtakingly bright and clear view even in live venues with intensely flickering lights. At the heart of the optical system is the high-grade high-refractive-index glass "BaK4 Porro prism" that delivers light to all four corners without leakage. It eliminates the shadows around the edges of the field of view and the darkness in the four corners that are common with inexpensive BK7 prisms, forming a high-contrast image with a perfectly circular exit pupil. The large central focus ring and right-eye diopter adjustment ring allow you to adjust for differences in left and right vision, ensuring you don't miss a single moment in a fast-paced stage performance. ■ Smartphone Ultra-lightweight at just 140g and dedicated eye cups to reduce hand shake To alleviate the fatigue in the arms and neck that is most burdensome during long performances lasting 2-3 hours, the internal structure has been redesigned down to the millimeter to achieve an ultra-lightweight design of just 140g. It is far lighter than a typical smartphone (approximately 200g) and is compact enough to fit in the palm of your hand, so you can hold it with one hand while holding a penlight or fan without getting tired. In addition, to suppress the minute shaking unique to high magnification, it comes with "hand shake reduction eye cups" that are uniquely designed to fit the facial structure of Japanese people. The three-point support structure that adheres closely to the brow bone and cheekbone physically suppresses hand shake, keeping a stable and clear view even with vigorous clapping or standing. It also has an interpupillary distance adjustment function, so it fits perfectly from children to adult men. ■ Complete 7-piece set ready to use right away and handling precautions This product comes with a complete 7-piece set that is ready to use right away for large-scale live performances and theater performances from the day it arrives. The contents include: binoculars, a soft storage case to absorb shocks, an ultra-fine microfiber lens cleaning cloth, image-reducing eyecups, a long neck strap for hanging around the neck, a hand strap to prevent dropping, and an illustrated Japanese instruction manual. (Includes a focusing guide for beginners). To ensure long-lasting use, gently wipe the lenses with the included cloth and store in a cool, dry place away from high temperatures and humidity. Please never look directly at the sun through the binoculars, as this can cause blindness. ■ Ruxis, a Japanese brand with thorough quality standards and support Ruxis is a Japanese brand specializing in binoculars and optical equipment, dedicated to "delivering the awe-inspiring experience of distant objects as they are."
