Eyecup Adjustment
Your 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 glasses, 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 position. 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.
