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.)
