Head Magnifying Eyeglasses Magnifier with 4 Lenses(BM-MG5022) 

Head magnifying eyeglasses are a type of magnifier that you wear on your head like a pair of glasses, but with magnifying lenses attached to them. These magnifiers are commonly used for activities that require close-up work, such as reading small print, doing detailed crafts or hobbies, and inspecting small objects.

The head magnifying eyeglasses typically come with four interchangeable lenses of varying magnification levels. The lenses are usually made of high-quality optical glass or acrylic, and range in magnification from 1.5X to 3.5X. The different lens options allow you to adjust the magnification to suit your specific task and vision needs.
