Have you ever found yourself unable to see the small print on a leaflet or the properties of a food item in the supermarket?
Problem solved with this small magnifying glass. Made of brass, it has sufficient magnification for this purpose.
The magnifying glass is an optical instrument consisting of a short focal length convergent lens, which deflects the incident light so that a virtual enlarged image of the object is formed.
The first works we have knowledge of date back to the 10th century, with the Muslim physicist Alhazen, who carried out numerous works with lenses and mirrors, later becoming considered the father of optics. It is also known that in 11th century China some of its inhabitants already used lenses to correct defective vision. The Englishman Robert Bacon is known for being the first Westerner to use lenses to improve vision.
It is also often used as an element to start a fire, allowing sunlight to enter through the magnifying glass. This can be considered a good way to start a fire, because it does not wear out like a lighter or flint and only requires sunlight.
Our keychain magnifying glass also comes in a nice case so you can make it an original gift.
It can also be used as a pendant.
