Eye Adjustments
Fig.1 INTERPUPILLARY DISTANCE ADJUSTMENT
HOW TO ADJUST FOR DISTANCE BETWEEN YOUR
EYES
The distance between the eyes, called “interpupillary
distance” (IPD), varies from person to person. To achieve
perfect alignment of lens to eye, follow these simples 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
Human eyes are as individual as fingerprints. This
binocular has a feature which allows you to adjust the
binocular to your vision. Follow the focusing instructions for
your binocular style.
Focusing

(front) lens of the side with the “diopter setting”
4. Using the center focus wheel, focus the distant
object being viewed.

Cleaning
1. Blow away any dust or debris on the lens (or use a
soft lens brush)
2. To remove dirt or fingerprints, clean with a soft
cotton cloth rubbing in a circular motion. Use of a
coarse cloth or unnecessary rubbing may scratch
the lens surface and eventually cause
permanent damage.
3. For a more thorough cleaning, photographic lens
tissue and photographic-type lens cleaning fluid or
isopropyl alcohol may be used. Always apply the
fluid to the cleaning cloth-never directly on the lens.
VERY IMPORTANT
Never attempt to clean your binocular internally or try
to take it apart.
