The Eyes
Alignment is obviously a visual process and the correct positioning of the eyes is directly correlated to how successful you are on the putting green. You can develop the most technically sound stroke in the world but if you do not aim correctly your superb technique will never do you any good.
The Positioning of the Eyes
The eyes give you all of your visual feedback as you try to hole a putt across a sloping green. Therefore it is very important that your eyes give you accurate information. Poorly positioned eyes result in false information and your ball will miss the hole. It is vital that you see the correct target line and not a false target line. Look at the following problem.
Imagine the putt is straight. If your eyes are inside the ball you see a target line that is different to the real target line. This creates problems when you aim the putter because you aim the putter as you see the target line and not how it really is. The result is a missed putt. Keep your eyes on the target!
