Also, if possible, look at a brick wall through the binos. Close one eye, open, then close/open the other eye. If the bricks and mortar lines "move" as you close/open your eyes, then the binos are out of collimation, and should not be purchased. Collimation is achieved when both halves of the binos are aimed at exactly the same place. If they are not, then your brain tries to compensate, and you end up with tired eyes and headaches as a result.
