One left in the quiver.
If you wear prescription spectacles, this is easy to try. If you do not, you'll require spectacles that you can wear comfortably.
1. Need second person.
2. Hold bow at full draw and shut your aiming/looking eye. Aim/look/sight on target with the eye that's the problem.
3. Second person, using dry marker, puts a mark on spectacle lens where your problem eye has centered on target.
4. Everybody relax.
5. Having identified the focus point that's messing you up, remove dry mark from the lens. Place a small square/piece of translucent cellophane tape at that focus point. Be sure to cover a small amount of lens surrounding the area. The idea is to obscure your area of focus. To be sure of doing this, you'll need to include a little extra area to account for you unconsciously trying to work around the obscured focus point.
6. Okay, you're ready to try shooting again. If things go well, what will happen includes the following. Your total vision will be essentially unchanged. However, when you acquire your shooting position, your dominant eye will no longer be dominant -- you've slightly blinded yourself, but only at the time of acquiring and firing. Your non-dominant eye becomes dominant, but only when you're shooting.
7. I make only one guarantee: the tape comes off so you do not harm your spectacles.
I developed this technique when I began bird hunting with a shotgun, right-handed. I am left-handed and found myself always shooting behind the bird until I did the tape thing.
Hope this helps.
