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. Bifocal reading glasses - Clip-on reading glasses are easy to use for both near and far vision. They attach easily to your glasses and are lightweight. Simply clip them onto your glasses, flip the lenses down when you need to read, and flip them up when you need to see things far away. There's no need to frequently take your glasses off or put them on. One-touch lens flip-up! The flip-up design allows you to see both far and near effortlessly. Another advantage is that you can continue using them even if you change your glasses to suit your preferences or prescription. High-quality flip-up reading glasses - The lenses are made of high-definition resin, allowing you to clearly see small objects and letters. The clip is made of alloy material, making it strong and durable, rust-resistant, and the screws will not loosen even if you frequently flip the lenses up and down. It is covered with silicone, so it does not affect the glasses frame or lenses. 30% Blue Light Cut - These reading glasses lenses are treated with blue light and UV protection, cutting 30% of the harmful blue light emitted from mobile phones and computers to protect your eyes. Ideal for those who need to use electronic devices such as mobile phones, computers, and televisions for extended periods. Lightweight and Compact - When you don't need to use your reading glasses, you can put them in the included case. The glasses case is very light and compact, so you can carry it in your bag or pocket and take it out whenever you need it. Clip-on reading glasses are lighter than flip-up reading glasses with frames, reducing strain on your nose and ears, making them suitable for long hours of reading or office use.
