You need to be for sure that you are shooting with your dominant eye. Try drawing your bow, getting comfortable and settled in and then peek through your peep with just that eye open. After you see the sight picture in focus, then open your opposite eye and you should basically only extend your field of view and low light shooting potential, not lose focus with your right eye. You'll be amazed at how much more effective you'll become at shooting at game, under the lower light conditions that are normally required, once you learn to shoot this way.
