Make the switch to shoot same handed as the dominant eye, you won't regret it. Much easier to train muscle memory than it is to retrain the brain and nearly impossible to overcome a dominate eye. I do everything right handed except shoot... left eye dominate so started shooting left handed at age 6. Spent 24yr in the USMC and countless rifle expert badges and shooting competitions won shooting left handed. After awhile it will become "natural" as muscle memory kicks in. Much easier to shoot with both eyes open (and better IMO) when shooting same handed as the dominate eye.
