This magnifier uses optical resin from Eschenbach's proprietary PXM, a material that has all the transparency, purity, hardness, and resolution required for lenses. You can see objects about 15.7 inches (40 cm) from the eye, and you can see them twice as large as possible, and you can see the magnification images at a reasonable distance. The dial allows you to adjust the viewing angle independently from the left and right. Not only does it look big, but it also gives you a clear view. Since it is a glasse-type, it is lightweight and easy to operate. The temples are flexible and can be adjusted to fit your ears. Convenient for detailed work and reading such as model crafts and handicrafts.
