Are Your Binoculars Properly Aligned?
Make sure your binoculars are well aligned by checking whether the two sides are magnifying the same image! You can get a quick idea by simply looking through the eyepieces and positioning an object against one edge of either the left or the right eyepiece and then closing that eye to see if the other circle of view has it positioned similarly. Do the same for the vertical plane. If the two barrels are not well aligned, your choices are to get them fixed, get another pair, or live with the headaches!
