Adjust the eyecups
Enjoy comfortable viewing even if you wear eyeglasses. Simply
twist the eyecups up or down to see the full field of view.
Keep the eyecups fully extended
if you aren’t wearing eyeglasses
or sunglasses. For the best views
when wearing eyeglasses, twist
the eyecups down.
Adjust the interpupillary distance
The interpupillary distance (IPD) is the distance between the
centers of the left and right pupil. Your binocular also has an IPD.
To see a single image free of shading, rotate your binocular until
its IPD aligns with your eyes.
Rotate the binocular barrels
inward or outward to align the
ocular lenses with your eyes.
The IPD of a binocular is the
distance between the center of
the left and right ocular lens.
