What is
Pupillary Distance
or
PD?
|
|
|
You might have guessed, it's the distance between the center of
the left and right pupil, in millimeter (mm).
|
|
|
|
|
|
Measure your
Pupillary Distance,
D.I.Y.
|
|
|
Get help from a
friend. Have your friend face you at arm's length. Have a millimeter
ruler ready.
|
|
|
Have your friend place
the ruler between your pupils and measure. IMPORTANT: leave no space between the ruler and
your face when taking measurement.
|
|
|
IMPORTANT: Look straight and level at your friend's
face while measurement is being taken.
|
|
|
If all your
friends are on vacation, you have to truly D.I.Y. by putting
the ruler on your own face and looking into a
mirror at arm's length.
