Plastic cased magnifiers are the most economical and come with relatively large lenses (30mm/1.25") and are good for insect, plant or spider identification. The basic model has a 5X lens. Two other models come with 2 or 3 5X lenses that when lined up form compound lens of 10X & 15X respectively. There is also a 10X 50mm (2") if you prefer a larger lens. All models have glass lenses.

Lens are a bit like prisms, they refract white light into its constituent colors. For many objects, this doesn't matter but for highly colored objects like minerals or even insects this can distort what you are seeing. Doublet & triplet lens loupes are cemented together to correct for this. Doublets for two colors & triplets for three.
If you are trying to decide whether you need a metal loupe or plastic one, check out our blog: What Magnifying Glass Do I Need for Biology?
Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.
