How to Repair Double Vision on Barska 10x50 Wide-Angle Binoculars

Введение

Binoculars are somewhat delicate, and when used outdoors in dynamic settings, they can sometimes sustain damage, which can knock the two sides out of alignment, culminating in double vision. Small changes in the positioning of the prisms can result in significant differences in the vision of the binoculars, and binocular manufacturers often hide the adjustment screws to discourage owners from attempting to repair them on their own. This guide will demonstrate how to find the adjustment screws on a pair of Barska 10x50 WA binoculars and adjust them to align the double vision.
