   How do reading glasses work? Do they mag

   I was having this argument at work.   
      
   Some claim that reading glasses work because they magnify small print.   
   They claim that reading glasses sold at drug stores are labelled in   
   terms of their "magnification power" or strength.   
      
   I was arguing that the goal of reading glasses is not to magnify, but to   
   move the focal point, and that they don't really perform any   
   magnification.   
      
   Who's right?   
      
   Do many people use the term "magnification" incorrectly when talking   
   about reading glasses?
