Have you ever found it extremely irritating and challenging to use binoculars since they require constant focusing and re-focusing, particularly when being passed back and forth between users? If so, you might wish to try perma focus binoculars, which have no central or eyepiece focusing system, and instead are permanently focused for average eyesight at moderate distances. If you are looking to buy binoculars that are very easy to use, and are only interested in using them casually, perma focus binoculars can be an excellent choice. You do, however, have to keep in mind that they have some drawbacks.
Having no means of refocusing on different images is not a great option for more advanced users, such as those interested in birding, since they cannot be adjusted for either close-up viewing or extremely long distance viewing. Additionally, the focus setting doesn’t work for everyone, so be sure to try them out prior to purchase to make sure they are a good fit for your eyesight. Additionally, images can sometimes be darker in a perma focus pair of binoculars, making them unfit for use in low lighting conditions.
Typically perma focus binoculars have a large depth of field, which means that they have a large area that remains in focus at one time. They have a particular distance, called the near point, which indicates the nearest distance that the binoculars can focus on. If you are purchasing a pair of perma focus binoculars, you’ll want to know that near point to make sure that they will be useful for your application. Typically these types of binoculars are useful for things like sporting events, where they may be passed around and where long-distance and also close-up viewing is not necessary. Most good quality binoculars do not need to have the focus readjusted very often, which is something you should consider before buying a pair of perma focus binoculars.
