I find that angles are at least as important as positions. My first 
pair of multifocals almost touched my face at the bottom. I was very 
uncomfortable trying to look downward steeply enough that I could see 
close-up. I figured that it would be better if my ears were a few 
millimetres lower, so the glasses wouldn't be tipped forward as much. 
Rather than having surgery, I just bent the arms of the glasses 
upwards, which produced the same effect. After that, the glasses worked 
very well. 
  
The general point is that, even though a new pair of glasses may have 
just cost several hundred dollars, you *must* be prepared to bend them 
about to find the best set-up. Often, you will find it only after a 
fair amount of trial and error.
