Classification of lenses
Convex lens A convex lens is a lens with a thicker center and thinner edges. Convex lenses have the function of converging light lines, so they are also called "converging lenses" or "positive lenses" (can be used for farsightedness and reading glasses). This type of lens can be divided into:

What is the definition of a lens and what is a lens?
There are six types of lenses. A lens is made according to the laws of light refraction. A lens is an optical element made of transparent substances such as glass, crystal, etc. A lens is a refracting mirror with two spherical surfaces, or a transparent body with one spherical surface and one plane. The image it forms has both real and virtual images. Lenses can generally be divided into two categories: convex lenses and concave lenses.

Lens knowledge points
Magnifier: A convex lens with a short focal length that can magnify smaller objects, but the object must be within one focal length of the convex lens, presenting a magnified upright virtual image
