Surely you've seen a magnifying glass in your life. In fact, I'm sure you've seen more than one. Magnifying glasses are relatively everyday objects that we have all used but in which we do not usually think.
Beyond knowing that they serve to better see some object, a text or anything else that you put it to, do you understand well what happens when you use a magnifying glass?
Since when are the loupes
In the year 1250 Roger Bacon invented the magnifying glass as we know it today. He got it by carving different lens lenses and later assembling them in frames. Before this invention there were already some approximations. In fact, in the year 1021 a similar device was already named in the "Book on optics".
This invention was used in the first instance by watchmakers and jewelers, since it helped them to develop their work with precision and extreme finesse. Little by little this invention was used in different works of crafts or merchandise, until it became completely popular.
How a magnifying glass works
When you need to see something in an enlarged way, you use a magnifying glass. You confront that object that you want to see better, or use it to read a text. With this simple object you get what you used to see before now appear bigger. Why?
What the magnifying glass does to achieve this magnification is to bend the light. When it passes through the convex lens with which the magnifying glass is formed, the light curves and offers a distorted image, specifically enlarged
