Does optical parallax cause you to aim outside the hole from 8 feet?

Most amateurs aim 3 to 6 inches away from where they think they are aiming due to dominant-eye parallax distortion.

If your head is positioned too far inside the target line, a straight line to the cup visually appears to point right of the target. To compensate, the golfer unconsciously pulls their stroke left. Conversely, positioning the eyes outside the line creates the illusion of aiming left, forcing an in-to-out push.

Truth: The Laser Mirror Alignment Calibration Certified putting specialists use specialized laser optics and mirror grids to determine your personal visual perspective. Matching putter neck offset (full shaft, half shaft, zero offset) and alignment markings (single dot, triple track, top line) to your dominant eye ensures that what looks dead-center to your eyes is physically aligned with the center of the cup.
