ThoughI don't have as severe a correction as you do, my glasses actually help me to align my eye properly over the arrow. If I look sideways over the arrow, my vision in my dominant eye is somewhat blurred. I correct this by turning my head more toward the target so I'm looking at the critter more directly over the arrow, not across it.
Opening your stance a bit helps accomplish this, as others have pointed out. Regardless, just need to turn your head more toward the target. Good luck.
