CLEANING
Proper cleaning of the lenses is essential
to maintaining the optical integrity of your
binocular. Dirty lenses diminish the amount of
light transmitted through the binocular and your
overall viewing experience.
1. Remove any dust on the lenses with a soft
lens brush or can of pressurized air.
2. Remove any fingerprints, stains or smudges
from the lens surface with a soft, clean lens
cloth or lens tissue by rubbing in a circular
motion. Start in the middle of the lens and
work your way to the edges. Breathe lightly
on the lens to provide moisture if needed.
3. For a more thorough cleaning we recommend
the use of a lens/optics cleaning kit available
at most photo or optical shops. Follow the
directions supplied with the cleaning kit for
best results.
