What are Binoculars, and how do they work?
Binoculars are two parallel mounted telescopes aligned so that they focus in the same direction. Two lenses are fitted at the end of the barrels on both sides. One lens is an objective lens that focuses on the object you are looking at; the other lens is known as the eyepiece lens. The eyepiece lens provides the final image to the human eye.
The light from the object shines on the objective lens, and then it passes to the eyepiece lens, which then forms a clear image of the object. The idea is magnified and synchronized by the eyepiece.
Prism binoculars are the most common type of binoculars, and they use a convex lens for both the eyepiece and the objective lens. It creates a prism system that is combined with the optical path. The inverted image is produced by the objective lens, which is then rectified, and then the user sees a clearer and more focused image of the object.

Working and Construction of Autofocus Binoculars:
Autofocus binoculars are also called self-focusing or constant focus binoculars. The Autofocus binoculars are permanently focused by the manufacturer for medium distances around 30 to 60 feet. You can have a clear view of things at and beyond 30 to 60 feet when you bring it up to your eyes. But you cannot focus on anything that is short-ranged.
They are excellent for witnessing the competition up close when you are in the sports arena. Autofocus binoculars are perfect for racing events and events where you are not focusing for an extended period.
Autofocus binoculars come in two different focusing options/designs. In one configuration, you cannot adjust the barrels of the binoculars. The second one allows you to adjust the barrels separately.
The type of design you should buy depends on how frequently and for what purpose you will use your binoculars. Technically the one that does not allow you to adjust or focus your barrels is what you cannot use frequently. The latter design is easy and convenient and can be used more regularly.

Do the Autofocus Binoculars focus automatically?
Autofocus Binoculars do not focus automatically, as they do not have automatic or self-focusing mechanisms in them. As they are designed to have a fixed depth of view that is 30 to 60 feet up to infinity, therefore they should be referred to as fixed-focus or always-in-focus binoculars. As they do not auto-focus things, instead, they have their focus adjustment set at a particular level that they are “fixed.”
Everything that is 30 feet away up to infinity will focus on the Autofocus or Fixed-focus binoculars. However, the diopter ring of these kinds of binoculars can be adjusted.
