Difference between lens and mirror equation

The points presented below are substantial so far as the difference between mirror and lens is concerned:
By the term ‘mirror’ we mean a shiny piece of glass, that is polished from the back, which reflects a clear image of the object, placed in front of it. On the other hand, Lens is a transparent piece of glass, with a spherical surface, that concentrates or disperses the rays of light falling on it.
A mirror is either plane or spherical. In contrast, a lens has two surfaces, at least one of which is curved inwards or outwards.
As the light ray strikes the mirror, it reflects off the light in a different direction, resulting in the formation of an image. Conversely, in case of lenses, the light ray enters the medium (lens), which refracts (bends) the rays in a different direction, creating a focus, from where the rays seem to originate.
To calculate the nature of images formed by a mirror and a lens, we use their equation, which is given as under:
Mirror Equation:
Mirror Equation
Lens Equation:
lens equation
Where v = Distance of image from the pole.
u = Distance of object from the pole.
f = focal length of a spherical mirror
