How do I calibrate binoculars?

As an outdoor enthusiast, you’ll be sure to own your binoculars. Good binoculars can help you have a great outdoor experience and enjoy better views from afar.  But there are also some people who, even if they have the best binoculars, don’t experience the beauty of the landscape because they can’t calibrate the binoculars to get a blurry lens.  So learning how to calibrate binoculars is an important thing.  Let’s learn how to calibrate binoculars.  

1. Adjust the tube and eyepiece  

Whenever you choose binoculars, make sure they are top-quality and can be used by people with and without glasses.  Apexel’s binoculars are decent and not too expensive, typically $40 to $70.  These types of binoculars are designed with everyone in mind.  

Before starting calibration, you should consider pupil spacing.  This means that the width of the barrel should match the width of your eye.  Adjust the distance between the two barrels.  Make sure they are not near or far from each other.  This is because the field of vision is always affected by the distance between the barrels.  At the right spacing, the view is very good.  It forms a perfect circle.  If you see a double shadow through binoculars, it is recommended to make a slight adjustment.  It will help you get a circular image.

2. Adjust eye mask to calibrate binoculars  

Turn the blindfolds counterclockwise and lift them off the main body of the binoculars.  

If you wear glasses, you can retract the blindfold or turn it clockwise to fit it against the body of the binoculars.  Extended eye masks allow you to wear them around your eyes, blocking light that you normally see in peripheral vision.  

Retracting the blindfold will give you a wider field of view, so if you want to see wider images, you may need to turn them clockwise.  

If you can easily use your binoculars without glasses, turn the blindfolds counterclockwise until they unfold sufficiently.  When fully unfolded, they fit your eyes perfectly.  In this case, the light doesn’t block your view, so you can get a better image.  

Most high-quality binoculars come with rubber cups.  They provide a comfortable viewing experience and protect your face from damage caused by continuous use.  Attaching these rubber cups to eyepieces is easy and fun.  For those who can only see through binoculars with glasses, place the rubber cup in the eyepiece when they are folded back.  

3. Focus binoculars  

(1) Install eyecups  

A rubber visor can prevent stray light from escaping into the observation effect;  If you want to wear glasses, please remove or fold them back.  Adjust the rubber eyecup and fold the eyecup when wearing glasses.  No glasses, glasses up.  Rotate and slide the rubber eyecup, while wearing glasses, turn the eyecup clockwise to the fully retracted position.  Without glasses, turn the eyeglass counterclockwise to the fully elongated position.  Once the rubber eyecup is set up, you will have a clear and complete view of the telescope from the right spot, with or without glasses.

(2) Adjust pupil distance  

The elbows and hand walls of both hands are clamped to the chest to form a support point for stable observation;  Remember to keep your hands and arms open.  The two eyes are adjusted according to each person.  Only when the two images are combined into one can the stereoscopic effect of binoculars be played.  If the pupil distance is not properly adjusted, the image you see may be uncomfortable.  Please carefully expand or close the binoculars when viewing two images.  ⒉ When two images merge into a perfect circle, please stop turning the mirror body.  

(3) diopter adjustment  

The elbows and hand walls of both hands are clamped to the chest to form a support point for stable observation;  Use the middle finger of your right hand to push the center focus wheel until it is clear.  

The right eyepiece of some binoculars can also be used for precise focusing, so users are required to rotate the central focusing wheel to make the left eye clear, and then close the left eye and use the right eye to compensate for more precise focusing, so that the right eye can be as clear as possible.  When adjusting the diopter of a zoom telescope, first set the magnification to the maximum.  The adjustment of the diopter will make it easy for users with poor eyesight.  

(4) Focus  

From now on, when looking at objects at different distances, just adjust the focus ring to align the focal length, without adjusting the focal length of the left and right eyepiece.  Never use binoculars to look at the sun or you will hurt your eyes.  

By following the steps above, you have learned how to calibrate your binoculars.  Hurry up to practice, welcome to leave a message to tell xiaobian, let xiaobian and you together solve the problem.  On your next outing, bring your favorite binoculars and have a great experience.
