Eyecup Adjustment
Your ALPEN binocular is fitted with eyecups which
can be rolled or twisted up or down (depending on
your model) to optimize the view for your eyes and
to exclude extraneous light. If you are not wearing
eyeglasses or sunglasses, keep the eyecups fully
extended („up" position). If you are wearing glas-
ses, roll down the eyecups or twist them to the
down position. This will bring your eyes closer to
the binocular's eyepiece (ocular) lens to ensure you
can see the entire image (full field of view with no
"cutoff" or "tunnel vision").

IPD (Interpupillary Distance) Adjustment
The distance or spacing between the center of the
pupils, called "interpupillary distance" (IPD) varies
from person to person. To adjust the binocular to
match your eyes, follow these simple steps:
1. Hold your binocular in the normal viewing posi-
tion. Grasp each barrel firmly.
2. Move the barrels closer together or further apart
until you see a single circular field (don't worry
about focus yet).
3. Always re-set your binocular to this position
before using it.
