Welcome to our shop We are excited to introduce our 5 Interchangeable Glasses. These glasses come with 1.0X, 1.5X, 2.0X, 2.5X, and 3.5X magnification lenses, allowing you to choose the perfect lens for your specific hand work needs. The lenses are made of high clarity optical acrylic, ensuring clear and accurate magnification. They are stored in a solid case with a lens holder, providing both protection and space-saving convenience. Assembling and using these glasses is a breeze. The lenses can be easily snapped in and out, and they can be adjusted more than 90 degrees for optimal positioning. When not in use, the lenses can be flipped up effortlessly. We understand that everyone has different preferences, which is why these glasses come with both eyeglasses style temples and a wraparound headband. This feature makes the glasses suitable for those who wear glasses and those who prefer the headband option. To ensure good visibility in any lighting condition, these glasses are equipped with 2 LED lights. The lights are bright and can be adjusted up to 45 degrees, allowing you to work comfortably in any environment. Please note that the lights are powered by 3 AAA batteries, which are not included. These glasses have a wide range of applications. They are perfect for activities that require hands-free focus, such as eyelash extensions, sewing, needlework, knitting, cross stitch, and embroidery (1X to 2.5X magnification). They are also ideal for close-up work like soldering, examining coins and stamps, using a jeweler's loupe, watch repair, crafts, manicures, and more. Note: 1.
