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.

If you use electronic products such as computers, mobile phones, game consoles, and TVs for a long time, it can reduce dizziness and eye fatigue caused by long-term use of the eyes.

[Necessity of blue light blocking glasses] Blue light from computers, portable game consoles, smartphones, tablets, etc. is short and scattered light, so people naturally adjust the lens of the eye to focus on the retina. As the focus continues to be adjusted, the focus adjustment muscles that adjust the lens become fatigued, causing eye fatigue, and further causing stiff shoulders and headaches. In addition, exposure to blue light at night can cause the body to gradually interfere with the process of falling asleep, leading to sleep disorders, disturbances in the body clock and autonomic nerves, and disrupting daily life. Therefore, blue light blocking glasses are necessary. [Computer glasses with clear lenses] When wearing glasses, we are concerned about the visibility and appearance. In particular, computer glasses are difficult to use for everyday use and difficult to match with fashion if the lenses are tinted or dark. Therefore, our computer glasses use clear lenses to not only protect your eyes, but also have a stylish design that can be used by a wide range of people, both men and women, without being fashionable.
