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 cut, prevent eye fatigue] The Bedtime blue light cut glasses lens substrate has a blue light cut factor added to absorb harmful blue light in daily life, and the surface of the lens has a protective layer that reflects harmful blue light and blocks 90% of blue light, ultraviolet rays, and UV400 that are harmful to the eyes. 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. [Computer glasses that also protect the skin around the eyes]: Our blue light blocking glasses can block 90% of blue light, preventing eye fatigue, eye pain, eye diseases, and preventing skin aging such as age spots, freckles, wrinkles, and sagging, and can regulate the body rhythm. Wearing these computer glasses will slow down the aging process and make you more beautiful. [Comfortable PC Glasses] The frame is made of ultra-lightweight material, making it thinner and lighter.

It is so comfortable that you will forget you are wearing glasses, and it is designed to prevent your ears and temples from hurting.

[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.
