Features of magnifying glass

Why can a magnifying glass magnify the image of an object? Have we noticed its characteristics? What kind of magnifying glass has the highest magnification?

Magnifying glass lenses are characterized by being clear and thick (convex) in the middle. Magnifying glasses are widely used in many aspects of people's life and production.
