Before you go looking for a pair of binoculars you need to sit down and decide what you will be using your new binoculars for. Night-vision binoculars are one of the most popular products in the market.
Here are some factors you should consider when choosing hunting binoculars. You position your telescope to look at the Moon, you see craters, and find that soon as you go to call someone to take a look, they take a look and it is gone. But the optical surfaces still need protection from scratches and other damage.
The coating reduces glare and protects your eyes from UV rays, and increases the definition and clarity of an object. When you are attempting a close up view of an object in the far distance, a very slight movement on your end translates into a big change in the area being viewed at the other end. In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields.
The best result is achieved when multiple layers of coatings are applied, to the front and rear of the lens. The first number separated by the "x" is the power of the binocular, and means the object being viewed appears to be that number of times closer than you would see without the binoculars. Using your binoculars outdoors will usually subject them to moisture.
When you travel, bring your binoculars, they will not add measurable weight to your luggage. And don't forget about small children and their fascination with dropping electronic equipment in toilets.
