What to Know When Choosing Bausch and Lomb Binoculars
From Little League games to vacations, binoculars are great to take with you anywhere a better look is welcomed. They reflect light that enters them to magnify what you see, making them clearer than your eyes can see on their own. In short, binoculars let you see farther away than you could normally. Many companies make binoculars, such as Bausch and Lomb. You can find binoculars for sale on eBay with a variety of features and price points.
What Bausch and Lomb binoculars are available?
Bausch and Lomb produces binoculars in compact, mid-size, and full-size ranges for a variety of needs. More compact binoculars will generally give less magnification. You'll find binoculars that can magnify things as relatively little as 8x (meaning they make a given object appear eight times the size it would to the naked eye) and then up from there.
The features of each pair of binoculars vary depending on the model and price. Some will offer fog proofing or image stabilization capabilities, while others can give you a variety of zoom strengths or are built to be more resilient. Some of the best binoculars even include anti-reflective coatings to make sunlight less harsh on your eyes.
What do magnification numbers like 10x50 mean?
When you look up binoculars, you'll find that each pair has two numbers associated with it, separated by an x. The first number tells you the magnification strength. For example, a pair of 10x50 binoculars can magnify what you see by up to 10 times.
The second number is the diameter of the objective lens (which is the lens at the far end, not where your eyes go), expressed in millimeters. The width of the objective lens determines the amount of light it will take in to make the image brighter.
For most general purposes, a magnification of 8x or 10x will usually suffice. The higher the magnification, the smaller the field of view is and the shallower the depth of field is. The image will be more easily affected by movement at higher magnifications as well, so a tripod or other support is helpful to keep the image clear.
What is the field of view and depth of view?
- Field of view: This refers to the width of what you can see through the binoculars at a distance of 1,000 feet. If you want a wider scene, select a bigger field of view. A higher magnification strength normally indicates a smaller field of view.
- Depth of field: This refers to the distance between two objects in sight when they're both in focus at the same time. Higher magnifications tend to reduce this distance.
Should you consider size and weight when choosing binoculars?
It's definitely a good consideration, as holding heavier binoculars in your hands for extended periods of time can be tiring. Some prefer smaller-sized items for the same reason. For travel, smaller, lighter models are often enough. However, there are many binocular accessories out there, such as tripods and straps, that can help mitigate any issues you may have with size and weight.
