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. Photochromic lenses automatically change color depending on the intensity of UV rays. In bright sunlight outdoors, the lenses turn a light gray. Indoors or in low UV conditions, the lenses become nearly transparent (please note that blue light blocking lenses typically have a slight yellow tint). Their adaptability to various lighting conditions makes them ideal for everyday use. Note: Please note that photochromic lenses may be less effective in low UV conditions, such as on cloudy days, in a car, indoors, or while driving. UV400 & Blue Light Protection: Equipped with UV400 lenses, these glasses effectively block UV rays with wavelengths below 400 nanometers (including UVA and UVB rays), reducing glare and reflections to protect your eyes from UV rays. They also filter harmful blue light emitted from electronic devices such as computers, smartphones, and tablets, protecting your eyes from UV rays.
