We gave our son a pair of Bushnell Binoculars, and we are having difficulty getting a good image. We have carefully followed the instructions with no luck. The problem is that we are getting a double image, and the only way to avoid this is to make the interpupillary distance so small that you can't see through with both eyes

The binoculars need collimation. The two sides are supposed to be parallel, if they are not you see two heads on horses, two footballs, two baseball bats etc. Check the binoculars for any external signs of damage. Are the front housings sitting properly in the body, is one of them not straight? If there is no obvious signs then you will need to take them to someone who can rebuild them for you. Usually the place where you bought them should be able to help you with a repair centre.
