Use an opaque occluder or patch over the non-shooting eye. I use a piece of Scotch Magic Tape over the lens of the shooting glasses (over the non-shooting eye). I am not cross eyed dominant and I use this method to cover my non-shooting eye. Never shoot with one eye closed, it causes the shooting eye to have it's pupil dilate the same as the shooting eye. This takes away the sharp focus from your vision. Also, holding the eye shut can fatigue the muscles in the eyelid and detract from concentration in shooting.BigMikeFromOlemiss said:
The Olympic Committee uses this method and they say as long as the non-dominant eye is similar in strength to the dominant eye, the method is as accurate as using the dominant eye for shooting. It is VERY counterproductive to try to have a cross dominant shooter change shooting methods to the other hand (ie: Right handed, left dominant eye to shoot left handed). This method works for stationary targets not for moving targets.
Another method I have seen is using the dominant eye to shoot the pistol. Occlude the non-shooting eye and turn the head slightly and use the dominant eye to sight the pistol. There can be a great deal of difference in sight in zero between the two eyes. You should also use the occluder when using the dominant eye in this manner.
