When most people think of a magnifying glass, the first person to come to mind is Sherlock Holmes, and without this trusty tool, many cases might've gone unsolved. What type of lens does a magnifying glass use to give us a closer look at objects?

A magnifying lens uses a convex lens to make items appear larger and clearer. Many eyeglass lenses use a combination of convex and concave lenses to suit individual needs.
