Acceptable deviation from axis value?

26 Jan 12 23:45:29

   XPost: sci.med.vision   
   From: not@home.com   
      
   My prescription for the left lens is:   
      
   -0.25  -3.25  173   
      
   When the glasses are made the left lens is actually:   
      
   -0.25  -3.25  175   
      
   Is that 2 degree difference for the axis within acceptable tolerance?   
   (I'm in the UK.)
