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
