About vision (Is left eye more clearer for a right hander?)?

This is some article. I think this might help..

imagine a right hander hold trigger using right hand and his left arm holding rifle "body" area, automatically he will positioning the rifle in his right cheek, thus its easier to aim using his right eyes. if he use left eye its harder because in that position right eye positioned staight with rifle scope/end. the reverse happened to left handler.
