  how do you measure your      Pupillary Distance ( PD ) ?
1,Place a millimeter ruler on the bridge of your nose.
2,Have a friend face you about arm's length away.
3,Have your friend measure the distance between the center of your pupils (the black dots in the middle of your eyes).
4,Repeat a couple of times for accuracy and use an average for your final measurement.


                            
                             *Note that the average PD is between 57 and 65mm.
      



            



SPH(or Sphere) indicates the eyeglass prescription power, or how strong your lenses need to be to correct your vision. For an indicator of how much magnifying power is needed in a bifocal or progressive lens to correct your vision problems, look for ADD.

CYL (or Cylinder) indicates astigmatism, a condition where the cornea is irregularly shaped causing blurred or distorted vision. It also tells the lens strength needed to fix it.

AXIS describes the degree and direction of your astigmatism.

ADD is added magnifying power in the lower part of a multi-focal lens. It’s used to correct presbyopia which is the inability to focus on close objects.
