adjust the center focus dial again until the
end of this process.
5.
Lower the binocular and move the objective
lens cover to cover the left objective lens.
6.
Still keeping both eyes open, find and view
the target again. This time, use the diopter
adjustment ring to bring the target into
sharp focus in the right eyepiece.
7.
Lower the binocular and uncover the right
eyepiece. You should now be able to view
through both eyepieces and adjust focus
using the center focus dial while maintaining
the proper amount of compensation
between your two eyes.
If the diopter adjustment ring is ever moved,
repeat this process.
(You may be wondering why you kept both
eyes open even though you could only see
through one optical channel at a time. It’s
because when you close one eye, your visual
acuity in the other eye changes slightly due
to the intricate and complex arrangement of
muscles surrounding both eyes. By keeping
both eyes open, your vision is as it would be
during regular use of the binocular.)
