**Japan I.L.K. Kodac Prescription Lenses (Non-Sterile)** **Boken-Oh Japan TAC Polarized Wrap-Around Blue Light Blocking Glasses** https://www.hwatang.com.tw/uploads/product/content/9f30188b4cedf52ad6dd81acf468b1f2.jpg **Product Introduction** Developed jointly by Japan I.L.K. and Japan Shisen-Do, the Boken-Oh (Adventure King) polarized blue light blocking lenses are made from TAC (Triacetate Cellulose) material, achieving over 99% polarization with excellent glare reduction for clearer vision. The B15 brown series lenses, through a special dyeing process, block most blue light and over 99% of UVA and UVB rays, reaching UV400 grade, ensuring both adults and children can safely enjoy outdoor activities. The lens surface is treated with a Hard-Coating for enhanced scratch resistance, extending its lifespan. **Product Features** **Boken-Oh TAC Polarized Lenses** https://www.hwatang.com.tw/uploads/product/content/ca30fd5ea9aeb335707c781175268906.jpg Glare from water surfaces makes it difficult to see objects clearly. Boken-Oh TAC polarized lenses allow light waves vibrating in a specific direction to pass through while blocking reflected light, effectively reducing glare and making it easier to see underwater conditions. Naturally, they also block harmful ultraviolet (UV) rays. https://www.hwatang.com.tw/uploads/product/content/d0a22d1d536ca79a849c027fba499e05.jpg Boken-Oh polarized lenses eliminate factors causing glare such as scattering, refraction, and reflection. This is achieved by sandwiching a polarizing film, functioning like blinds, between the lenses to block interfering light from below, ensuring clear vision. Furthermore, a special film with alternating transparent and opaque layers, through the polarizing film, blocks excess light from above, below, and at angles, allowing only the desired target object illuminated by natural light to be seen. **B15 Brown Series Blue Light Blocking Lenses** https://www.hwatang.com.tw/uploads/product/content/dd32c483ccacf51273dd36945312b1c7.jpg These lenses filter out blue light and distracting glare, enhancing object contrast. They are effective even against backlight during dawn and dusk. https://www.hwatang.com.tw/uploads/product/content/f804e7d19b1249868462d106ab115d13.jpg "Ultraviolet rays" cannot reach the inner eye. However, "blue light," part of visible light, can penetrate deep into the eye. "Light-filtering glasses" block ultraviolet rays while also filtering out blue light. Tested against US standard ANSI Z80.3:2018 and European standard EN ISO 12312-1:2013 (A1:2015), Boken-Oh B15 brown series TAC polarized blue light blocking lenses block over 99% of UVA and UVB rays, reaching UV400 grade. https://www.hwatang.com.tw/uploads/product/content/f50a5992323bced07d3cd31f42dd9adf.jpg **Precautions** 1. Please choose and wear according to the advice of an ophthalmologist or professional optometrist. 2. To clean lenses, dilute neutral dish soap with cold water, wash, and then dry with a paper towel or short-fiber tissue. 3. Do not wipe the lenses with volatile cleaning agents (such as stain removers or alcohol), as this will damage the lenses. **Product Specifications** Lens Material: TAC (Triacetate Cellulose) Polarized Lens Filter Category: 3 Lens Color: B15 Brown Lens Coating: Hard-Coating UVA Transmittance (315-380nm): 0% (UVA blocking rate over 99%) UVB Transmittance (280-315nm): 0% (UVB blocking rate over 99%) Supervised by Japan **Medical Device Information** Approval Number: 衛部醫器輸壹字第014285號 Manufacturing Date: See the label on the product packaging.
