Steps to Fix Binoculars with Double Vision
We’ll walk you through the steps to fix binoculars with double vision and get them back to their optimal viewing capabilities.
Identify the Problem
Before attempting to fix your binoculars, it’s essential to identify the root cause of the double vision. There are several reasons binoculars may develop double vision, such as misaligned prisms, loose internal components, or lens damage.
Take a closer look at your binoculars and try to identify any visible signs of damage or misalignment.
Adjust the Diopter
If you wear glasses or have a significant difference in your eye prescription, your binoculars’ diopter adjustment may need to be adjusted.
The diopter adjustment is typically located on one of the eyepieces and is used to adjust the focus on one side of the binoculars to compensate for the difference in your eyes.
To adjust the diopter, first, focus on a distant object with one eye, and then close that eye and open the other. Adjust the diopter until the image appears clear and in focus.
Align the Prisms
If the double vision is caused by misaligned prisms, you can try to realign them by adjusting the screws on the binoculars’ housing. The housing is typically located at the center of the binoculars and contains the prism system.
