This tells you how many times an object is magnified when observed through the binoculars.

The diameter of the objective lens will impact how bright, sharp, and comfortable your view is. Generally, bigger is better.

Lens coatings reduce light loss and glare to increase contrast and diminish eyestrain. Coated: one layer on external surfaces only. Fully coated: every surface is coated. Multi-coated: multiple layers on some of the surfaces. Fully multi-coated: multiple layers on every optical surface.

The widest dimension of circular viewing area that you can see.

The nearest distance at which the binoculars will focus on an object.

The diameter of the objective (outside) lens divided by the binocular's magnification. It indicates the amount of light that reaches your eye (most noticeable in low light conditions). Higher numbers offer brighter images.

The distance between the eyepiece and your eye while still allowing entire field of view. Long eye relief is good for eyeglass wearers.

Waterproof binoculars are assembled with O-rings and are purged with nitrogen to avoid condensation. They are ideal for boating or use in rainy weather.
