Different magnifying glasses have different focal lengths, and the focal length needs to be adjusted according to the actual situation to achieve the best magnification effect.

Magnifier, also known as convex lens, its amplification function is based on the principle of light refraction. When light passes through a convex lens from air, refraction occurs, causing the light to focus towards the center of the convex lens. Therefore, when we place an object within the focal length of the magnifying glass, the light emitted by the object is refracted by the convex lens, forming a magnified virtual image on the other side of the magnifying glass. This is the basic principle that magnifying glasses can magnify objects.
