Troubleshotting Binoculars

Common Issues

When I try to focus my binoculars, I can get the right or left side focused, but not both at the same time.

Cause: Everyone’s eyes are different, especially the focus relationship between our left and right eyes. To correct for this, all binoculars can focus one eye separate from the other, with the diopter adjustment. This tunes them to a specific user. If you look through a pair of binoculars that you have not set up for your unique eyesight, you may not be able to get both eyes focused on the same object.

Solution:All Leupold binoculars will have a control to focus the right eye independently. This will either be a knurled ring around the right eyepiece, or locking control by the center focus. Follow the steps below to tune your binoculars to your eyesight:

  • Locate an object you can see clearly and find again easily through the binoculars. Objects between 50 and 100 yds work best, but any object you can focus on will work.
  • Close your right eye and use the main center focus of the binocular to focus on the object while only viewing with your left eye.
  • Now, close your left eye and use the diopter adjustment around the right eyepiece, or on the center focus wheel to focus on the same object with your right eye only.
  • Open both eyes. If you notice any focus difference or eye strain, make very small corrections to the diopter adjustment until it goes away.

If you share binoculars with someone who has different eyesight than you, you may have to repeat this process often.
