EYE ADJUSTMENTS (Fig. 1)
How to Adjust For Distance Between Your Eyes
the distance between the eyes, called “interpupillary distance,” varies from person to person. to
achieve perfect alignment of lens to eye, follow these simple steps.
1. Hold your binocular in the normal viewing position.
2. Grasp each barrel firmly. Move the barrels closer together or further apart until you see a
single circular field. Always re-set your binocular to this position before using.
How to Adjust For individual Eye Strength
As individual eyesight varies from one person to another, Bushnell binoculars have a diopter setting feature which allows you to fine-
tune the binocular to your vision. Follow the focusing instructions below for your binocular.
FOCUSING
1. Adjust interpupillary distance. (Fig. 1)
2. Set the “diopter setting” (Fig. 2) to zero and view a distant object.
3. Keep both eyes open at all times.
4. Using a lens cover or your hand, cover the objective (front) lens of the same side of the binocular
that has the “diopter setting”. this is usually the right side.
5. Using the center focus wheel, focus on a distant object with fine detail (e.g., brick wall, tree branches, etc.) until it appears
as sharp as possible.
6. Uncover the objective lens on the diopter side, cover the other objective lens, then view the same object.
7. Using the “diopter setting” adjustment ring, focus the same object being viewed. Caution should be used as over turning or
forcing the diopter eyepiece can cause damage or cause the eyepiece to break away from the chassis.
8. Your binocular should be adjusted for your eyes. Focus at any far or near distances can now be attained simply by turning the
center focus wheel. Make a note of the diopter setting for your eyes for future reference.
