Since the light has been refracted, or bent as it has been directed through the lenses, by the time the viewer sees the image it is back to front, and upside-down. Binoculars repair is the last thing on the mind of a user as they purchase their prized tool.
High power spotting scopes, or binoculars, where the power exceeds 10x will need to be mounted on a tripod. Focus adjustments on each set of binoculars are different, some binocular lenses can be focused independently while others can be focused at the same time by turning a little wheel in between the telescopes. When hiking or orienteering, binoculars will be very useful, but it is important to note that optics are very fragile, and so plastic lenses over glass ones, and a rugged case are probably going to be more important than high power, or the ability to use them at night.
As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars. Binocular lens protectors drive water off the lens surface of both objective lenses and eyepieces, helping eliminate glare caused by water droplets.
When you consider the cost of a single hunting trip, quality three to five hundred dollar binoculars are a great investment. A good warranty is your ticket to trouble free repair.
