I was struggling with this early this year. I am right eye dominant and also see my line on a green as a straight line, not as the path the ball actually takes. This makes me very dependent on the line on the ball, and I consistently felt like I couldn’t get that line where I wanted it. No matter how many times I backed off and realigned I never felt comfortable. I was searching the internet for help, but came across something interesting watching Bryson play. He would use the shaft of his putter to draw a line between his spot and his ball. I picked this up and it has helped immensely. I find my spot to putt to, line my ball up to what should be that line, and check it by holding my putter shaft up and closing my left* eye. I look along the right side of my putter shaft to see the line on my ball follow my putter shaft to that spot. From there I feel comfortable to fully trust my line on the ball and putt.
Hopefully that is descriptive enough to understand my process. Best of luck right-eye gang!
