   Lens frames bend more than that.   
   A short breeze of wind (so to say) will move the whole thing   
   far more than your numbers. Noses too have tolerances.   
      
   The question is (you did not mention)   
   how you measured those numbers and to what accuracy.   
      
      
   Summa summarum I say: forget it.
