Binocular optics setting/adjustment
Adjust the interpupillary distance
The interpupillary distance is the distance between the centers of the
left and right eye pupils. Match the interpupillary distance of your eyes
to that of the binocular so that you see a single image that is free of
shading.
Rotate the binocular barrels inward or outward to line your eyes up with
ocular lenses.
Adjust the eyecups
The eyecups twist up and down so that any viewer can see the full field
and enjoy comfortable viewing with or without eyeglasses. There are 2
options for your choice.
When not using eyeglasses, please twist the eyecups up or keep the
eyecups fully extended. For the best viewing when viewing through eye-
glasses, twist eyecups down.
