Learn to shoot left handed, or cover the left lens of your shooting glasses with a piece of opaque tape.
The tape will still allow light through but will blur the vision of the left eye, which forces the right eye to take over. Tried this with my wife and it worked for a while. Then she went out and bought a left handed bow and now shoots left handed only.
Two advantages to LH shooting in your case. First, your scores WILL improve sooner rather than later because you will not be fighting your eye dominance. Secondly, You have spent your whole life supporting the heavy end of the weapon with your weak side. Switching to LH will put your stronger arm at the heavier end of the gun, giving you more stability, thus helping to improve your scores. It's gonna feel wierd at first (trust me, lost the vision in my right eye and had to do the same thing), but in the end it will be worth it. Hope this helps.
If it ain't got papers, deport it.
