Understanding eye dominance, for many people, is much easier that dealing with it. Like many, I am cross-dominant, and it took study and practice to overcome the inherent problems. Learning to shoot with both eyes open can be very helpful, and there are many articles out there on how to do it correctly. Another helpful technique is to learn to aim with your presentation. For this I highly recommend Mike Ochsner's book "Red Dot Mastery." However, aiming with presentation is not exclusive to using an optic. Mike describes several skill development techniques that can be done at home without a gun.
