Nikon Lookout IV Double-vision
If you are getting double images, it is more likely a problem with alignment, rather than an IP adjustment, especially if you are getting headaches. The two prisms in a binocular must be precisely aligned so that both barrels are essentially looking at the same precise point. If they are not, your eyes will literally be pulled in two different directions, hence the headache. In minor cases of poor alignment you will still see a single window, but feel a strain on your eyes. When you are seeing double images, though, you have a serious case of poor alignment. Either way, it is time for reapir.
Do not attempt to take your Nikons apart and try it on your own. That not only requires special tools, it also voids any warranty. If you want to explore getting them repaired through Nikon, their number is 1-800-645-6678. If you want to go it on your own, Cory Suddarth at 1-918-650-9087 is an excellent optics repairman and restoration expert. We recommend him highly.
