To putt well, your eyes need to be properly aligned and working together, according to Pacific University College of Optometry in Oregon. Golfers who have trouble are those whose visual alignment fluctuates, which may be due to stress or fatigue. The cause may also be due to glasses or contact lenses.
Only wear distance vision glasses for golf. Or get a segment bifocal which has a small near-vision segment in the corner of one lens.
