longer focal length or lower optical power is associated with larger magnification of distant objects

In telescopy and most photography, longer focal length or lower optical power is associated with larger magnification of distant objects, and a narrower angle of view. Conversely, shorter focal length or higher optical power is associated with a wider angle of view. In microscopy, on the other hand, a short objective lens focal length leads to higher magnification.
So that is why when the lens goes out more, there is greater magnification it is like Far sighted
Focal length is longer. for greater magnification. http://isleofmanmansions.blogspot.com/
