Contrary to a parfocal zoom lens, which maintains focus while the lens zooms, a varifocal lens is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes (focal length and magnification change). You can change the top and bottom limits of a varifocal camera’s view angle. This indicates that you may manually adjust the zoom level and view angle.
The fundamental benefit of varifocal lenses is that they give the user the ability to wear just one pair of glasses for full distant vision. They are, for the most majority of individuals, the most practical solution to the issue of the necessity for separate corrections for far distance, intermediate, and near.
Varifocal glasses, sometimes referred to as varifocals, varifocal lenses, PALs, or progressive lenses, contain various focal points between the top and bottom of the lens and a gradual strength change in between. This enables you to use a single lens to view all distances and focus points.
