What is a magnifying glass used for?

A magnifying glass makes small objects appear larger using a convex (converging) lens. When an object is placed within the focal length, the lens produces a virtual, erect, and magnified image.

Uses: Reading fine print, examining lab specimens, jewellery inspection, philately, forensic investigation, watchmaking.
