I'm guessing you shoot right handed and are left eye dominant, otherwise you have no problem. With rifle shooting the cross dominance is not an issue, as the "off-side" eye is usually closed anyway. The rub is when shotgun shooting, which is properly done with both eyes open. If you're right eye dominant and a right handed shooter, with both eyes open the dominant eye will be looking down the barrel and aiming properly. With cross dominance the left eye tries to aim and will be way off. Point your finger at something with both eyes open, then close one, then the other. Your dominant eye will be looking right down your finger, while the other will be way off center. Same principle applies when aiming with both eyes open with a gun. Some people wear an eye patch or a dark lense in their shooting glasses. Or you can close one eye. Whatever works for you.
Good luck.
