The virtual image, which gets created, appears larger than the real object. This is due to principles of geometry. The eyes trace the light rays back in parallel lines to the virtual image and since the virtual image is farther from your eyes than the object is, the object appears bigger.The magnification of a magnifying glass also depends on where it is placed between the user's eye and the object being viewed. It also depends on the total distance between them.If you have a poor or low vision, then reading magnifiers will work like a charm and help you in reading a book, magazine, newspaper, etc. Nowadays, full page reading book magnifiers are also available.

The glass (hand lens) is a convex lens, which makes objects appear larger than they actually are. This is because their convex lens i.e. lens curved outside, refract or bend light rays to converge. When light bounces off an object and travel to the eyes, these convex lenses bend the parallel rays so that they converge and create a virtual image on your eyes retinas.

It is strongly recommended to support the lens as the e-mount and camera housing can be damaged by the weight of the heavier and bigger BNC-R lenses and mount.

A magnifying glass is used to make tiniest things look bigger. It is a form of a microscope. Consisting of a single lens, it magnifies an object whenever the glass is held up to the object.  The lens is mounted in a frame.
