Binoculars function: Binoculars work by magnifying the image you wish to see - they make the image appear larger and colser than it really is. They accomplish this by using the glass lenses (1)inside the binoculars to eliminate stray light around the objest and focus the light reflecting of the object ot make it appear birghter and clearer. Your binocularsare disigned to magnify objects eight times.

Binoculars usage: The binoculars can be adjusted to your eyes easily. Spread your binoculars out as wide as possible and put them up to your eyes. It probably looks as if you arekooking though two separate tubes. You have possibilities to impede this:
1. Spread the two lenses on their main hinge so that the eyepieces fit the width between your eyes comfirtably and so the two circles of vision blend into one.
2. Turn the central focusing wheel until you can see as clearly as possilbe.
