BASIC OPERATION
Adjust the Eyecups
The eyecups on your binocular either twist up/down or fold up/
down allowing anyone to obtain a full field of view and comfortable
viewing despite differences in facial structure, and for use with or
without glasses.
When not using glasses,
generally the eyecups will be
fully extended. When using
glasses, generally the eyecups
will be fully collapsed.
Adjust the Interpupillary Distance
The interpupillary distance (IPD) is the distance between the
centers of the left- and right-eye pupils. Match the IPD of
your eyes to the binocular so that you see a single image free
of edge distortion.
IPD
Rotate the binocular barrels inward
or outward to line your eyes up with
ocular lenses.
Distance between the centers of
the ocular lenses.
