How To Focus Your Binoculars

The number of people buying binoculars continues to increase by the day, thanks to the advertising by marketers and the great interest in outdoor activities. However, the truth is that the greatest percentage of users cannot focus their binoculars; and we are not just talking about children here. Basically, there are two common focusing systems that are used in binoculars; the center focus and the individual eyepiece focus.

Individual Eyepiece Focus: The individual eyepiece focus is easy to use and understand and is used to focus sealed optical tubes; it is almost always used for focusing systems that are used in waterproof binoculars. This is an import feature because the human eyes are not necessarily the same and even your own two eyes are actually different even though not most people think so. The individual eyepiece focus, therefore, means that you focus the binoculars so that it fits your own eyes; you are going to focus the left eyepiece to your left eye and right eyepiece to your right eye since there is nothing like a centrally located focusing mechanism.

Start by looking at something at a distance and close the right eye or the front of the right binocular; focus the left eyepiece to your left eye using the focus ring that is next to the eyepiece. Once you are done, close the left eye or the front of the left binocular and focus the right eyepiece to your right eye and you are done. With this, you are done until you need to view something at a distance where you may need to repeat the process.

The center focus: The center focus is the most common one since most people find individual eyepiece focus time-consuming but only a small number of people are able to do it correctly. Start by aiming your binoculars at a distant item, close your right eye or simply cover the front of the right tube, use the left side of the binoculars to focus the left eye using the center focus control; this is part of the pivot shaft between the two tubes. You need to remember that the left eyepiece doesn’t focus on the center focus in many cases. Now you can close the left eye and use the same procedure, try to focus the right hand side tube by using the focusing ring next to the right eyecup; do not touch the center focus control when you are focusing the right eyepiece to your right eye and you are home and dry.

The process you have accomplished enables you to adjust your binoculars to your individual eyes; this is because almost everyone’s right and left eyes are different. Once you have accomplished this, all that you may need to do is to use the center focus control whenever you look at objects in the distance.
