INSTRUCTIONS FOR USE
Your Bausch & Lomb
®
binocular is a precision instrument designed to provide many years of
pleasurable viewing. This booklet will help you achieve optimum performance by explaining how
you can adjust the binocular to your eyes, and how to care for this instrument. Read the
instructions carefully before using your binocular.
EYE ADJUSTMENTS (Figure 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, all Bausch& lomb® binoculars
have a diopter setting feature which allows you to fine-tune the binocular to your vision.
Follow the focusing instructions below for your type of binocular.
FOCUSING
1. Adjust interpupillary distance. (Figure 1)
2. Set the "diopter setting" (Figure 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. (The left side on
zoom models.)
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.
"ZOOM" FEATURE (Figure 3)
1. Follow the steps for focusing as outlined under Focusing.
2. When focusing a "zoom" (variable power) binocular, it is best to begin at high power.
This will reduce or eliminate the need for focus readjustment when zooming between
high and low powers. Set the "zoom" control at the highest power indicated and
focus on a distant object with fine detail.
3. Adjust your binocular for individual eye strength using the "diopter setting" as outlined
in the instructions for Focusing.
4. Your binocular is now adjusted properly for your eyes. You may now "zoom" "out" or
"in" on any distant object.
Note: To focus on an object at a closer distance, focus on the object at high power
first and then adjust the "zoom" control to the desired lower power. With any "zoom"
instrument, better quality images are possible at lower powers.
WATERPROOF-FOGPROOF
Your Bausch& Lomb® binocular may be designed and built utilizing the latest waterproof
and fogproof technology. Bausch& Lomb® waterproof models are O-ring sealed for
complete protection. Fogproof protection is achieved from dry nitrogen purging to remove
all internal moisture.
EYECUPS (Figure 4)
Your Bausch& Lomb® binocular is fitted with rubber roll-down, pop-up, or twist-up
eyecups designed for your comfort and to exclude extraneous light. If you wear
sun/eyeglasses, roll down the eyecups. This will bring your eyes closer to the binocular lens
thus providing improved field of view.
INSTRUCTIONS FOR CARE
Your Bausch& Lomb® binocular will provide years of trouble-free service if it receives the
normal care you would give any fine optical instrument. Non-waterproof models should
not be exposed to excessive moisture.
1. If your binocular has roll-down, flexible eyecups, store it with the eyecups up. This
avoids excessive stress and wear on the eyecups in the down position.
2. Avoid banging and dropping.
3. Store in a cool, dry place.
4. Looking directly at the sun with your binocular may be very harmful to your eyes.

CLEANING
1. Blow away any dust or debris on the lens (or use a soft lens brush).
2. To remove dirt or finger prints, 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. A "microfiber" cleaning cloth (available at most
photo dealers) is ideal for the routine cleaning of your optics.
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.
