A. Hands-free Magnifying Glasses - Compared to a handheld magnifying glass, magnifying glasses can be worn on your eyes. They free your hands to do anything and come with built-in powerful LED lights. B. 200% Magnification Lens - Portable magnifying glasses with light magnify up to 2.0 times, ensuring clarity and detail. They are suitable for close work, crafts, jewelry work, painting, reading books, documents, newspapers, and instructions, as well as for work and hobbies. C. Bright LED Light, Rechargeable - Magnifying glasses with light on the sides of the frame allow you to read books, documents, newspapers, and instructions, and work comfortably at night without disturbing your partner. You don't need to worry about changing the battery, as you can charge it anywhere with the USB charging cable. If you can't turn on the light, charge it first. D. Blue Light Protection - These LED light magnifying glasses have a blue light blocking lens, which can prevent blue light from irritating your eyes when working on a computer or mobile phone, reducing visual fatigue or headache. They also come with an anti-blue light test flashlight and test paper to help you test the effect of blue light.
