There's a couple options, none without a downside.
First is simple, close the off side eye. This means one loses stereoscopic vision and depth perception. It's workable, some folks do very well.
Second is almost as simple. Put some opaque tape on your shooting glasses on the off side that masks the bead. Again, some folks do well here.
Brad Dysinger, ATA Hall of Famer, has mixed dominance. He just shoots that way and has run 500X500. Don't ask me how he does it.
HTH....
