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.

Blue light protection: Blue light blocking lenses are used to block harmful blue light emitted from digital devices, reducing eye strain.
Color-changing and photochromic function: Blue light-blocking glasses that use photochromic lenses change color in response to ultraviolet rays, becoming dark like sunglasses outdoors and clear indoors. You can easily adapt to cloudy and sunny weather. Note: Photochromic lenses with blue light-blocking coating on the surface may appear bluish when viewed from the outside when they turn gray. This is because the lens itself turns gray and the blue light-blocking film on the surface reflects blue light, which is a natural phenomenon caused by light interference.
High-quality materials and comfortable: Made of high-quality TR90 and metal materials, these glasses are comfortable and durable for everyday use. They are ultra-lightweight and do not feel oppressive even when worn for long periods of time, and are less likely to hurt behind the ears. If you choose a pair with adjustable nose pads, the fit will improve, they will not slip, and there will be less pressure on your nose.

Accessories: Outer case, glasses case, glasses, glasses cloth, blue light cut test set, discoloration instructions. Note: Photochromic lenses with blue light cut coating on the surface may appear bluish when viewed from the outside when they turn gray. This is a natural phenomenon caused by light interference, as the lens itself turns gray and the blue light cut film on the surface reflects blue light.
