How to Calibrate Binoculars

Seeing detail from a far distance is almost impossible without a good set of binoculars. If you’re trying to birdwatch or see something from far away, you’ll need to make sure your binoculars are correctly calibrated to your eyes. To do this, you’ll need to properly set the distance between both eyepieces. Then, you’ll adjust the focusing rings, or diopters, to make the image sharp and clear. When done correctly, amazing details will be visible from a far distance.

EditAdjusting the Barrels and Eyepieces

  1. Rotate the eyecup so it’s extended if you don’t wear eyeglasses. Turn the eyecups counterclockwise to raise them up from the body of the binoculars. If you wear eyeglasses, you can keep the eyecups retracted, or turn them clockwise to tighten them against the body of the binoculars.[1]

    • Extending your eyecups will allow you to fit them around your eye, which will block out light you’d normally see in your peripheral vision.
    • Retracted eyecups will give you a wider field of view, so you may want to turn them clockwise if you're trying to see a wider image.
  2. Attach the rubber cups to the eyepieces if you have them. Some binoculars come with a rubber cup that you can fit around the eyepiece. If yours came with one, use it for more comfortable viewing. Fit the slightly recessed end of the cups over both of the eyepieces so that they are snug and don’t slide off.[2]

    • If you want to use the rubber cup but have glasses, roll the extended rubber back so that you can look through the binoculars with your glasses on.
  3. Grip both barrels and bend the center of the binoculars to fit your eyes. The barrels are the 2 tube pieces connected to the lenses. Look through the binoculars and grip the barrels by the sides. Then, bend your binoculars up and down at the center so that both your eyes fit over the lenses. When you look through the eyepiece, you should see one circular image. If you see a double image, then you need to readjust the barrels.[3]

    • The distance between everyone’s eyes differ, so you’ll need to adjust the barrels to fit your eyes so that the binoculars fit your face.

EditFocusing the Binoculars

  1. Hold the binoculars up to your eyes and focus on an object. Select a stationary object in the distance to look at. If the image is blurry when viewing it through your binoculars, it means that you have to adjust the focus.[4]

    • Even if the image is clear, you may want to calibrate your binoculars to achieve an even sharper image.
  2. Cover the right lens on the binoculars and focus with your left eye. Hold the palm of your hand over the right lens to cover it. If the image is blurry when you look with your left eye, it means that you need to adjust the focusing ring, in the center of your binoculars.[5]

    • The focusing ring puts the object that you're looking at in focus while the diopter on the right eyepiece compensates for the differences between your left and right eye.
  3. Adjust the focusing ring in the center of the binoculars. The focusing ring is the wheel in the center of your binoculars, in between both barrels. Rotate the ring left and right until the image becomes clear in your left eye.[6]

    • After you’re done focusing the left eyepiece, take your hand off the lens.
  4. Cover the left lens and focus with your right eye. Close your left eye and try to focus on the image with just your right eye. If the image isn't clear, it means you need need to adjust the diopter on the right eyepiece.[7]

    • If the vision in both of your eyes is the same, then you might not have to adjust the diopter on the right eyepiece.
  5. Adjust the diopter on the right eyepiece. The diopter is the wheel on the eyepiece. This helps compensate for the differences in vision in your individual eyes. Rotate the diopter until you can see the object clearly with your right eye while the left lens is still covered.[8]

    • Focusing on one eye at a time will make calibrating your binoculars easier.
  6. Look through the binoculars and note the diopter settings. Look through the binoculars with both eyes. The binoculars should feel comfortable and the object should be in focus. Most binoculars will come with markings on the diopter. Take note of where both diopters are so you know where to adjust them if they get changed or someone uses your binoculars.[9]

    • Once you get the correct calibration, you shouldn’t have to change it again.
    • If the image is still blurry, you may need to adjust the diopter in the center of the binoculars.
