A magnifying glass is a convex lens that is used to produce an enlarged image of an object. The lens is usually mounted in a frame (metal or plastic) equipped with a handle. A magnifying glass creates an enlarged virtual image of the object beyond the lens. For this to happen, the distance between the lens and the object must be less than the focal length of the lens.
A magnifying glass can also be used to focus light, so as to concentrate solar radiation to create a hot spot in the fire for fire initiation.
High magnification lenses (8-10x) are used in iridology, together with an LED bulb, to study the characteristics of the iris.
The magnifying glass is the icon par excellence of crime literature and detective stories in general, especially those of Sherlock Holmes. On the Internet and within the graphical interfaces of operating systems and software in general, the icon representing the magnifying glass symbolizes the search function.
People with vision problems can sometimes help themselves with magnifying glasses and other devices useful for the visually impaired.
