 This
measurement is used to determine where the center of the lens is to
be positioned in front of your pupil when your prescription glasses
are made.
It is
recommended you ask your optician or Doctor for your pupillary
distance measurement. Nevertheless it is a simple measurement which
can be taken yourself but for best results we suggest asking a
friend to assist.
