Now our professional golfer, who essayed the task of playing blindfolded golf, was perfectly correct in stating that it is not necessary to keep one's eye on the ball in playing golf, for the simple reason that the eye has fulfilled its function and has gone out of business, so far as regards that stroke, long before the head of the club has come into contact with the ball. It is this fact which makes us so prone to lift our eyes, and with them our heads, which of course is fatal to good golf. I go so far as to say that if Vardon in his drive could be automatically blindfolded when his club was two feet from his ball, and that he could accustom himself to keeping his head still after he was blindfolded, it would not affect his drive in the slightest degree, for the very simple and all-sufficient reason that the eye has finished its function in connection with the golf stroke for a very considerable period before impact takes place. It has assisted the golfer to take his proper stance and address, and has aided him in judging his distance, but the arc of the golf stroke is practically settled almost from the instant that it starts on its downward path.
The duration of impact in a drive at golf has been measured by the most competent authority to be one ten-thousandth of a second. Photographs of the impact of the golf club with the golf ball taken at the one twelve-hundred-and-fiftieth of a second, are merely blurs. There is no clear definition of the club whatever. We can see from this that the rate of speed at which the golf club is travelling is extreme, even had we not the scientific measurement of the exact amount of time consumed during the contact. It will be obvious to a very ordinary understanding that when a club is travelling at this terrific pace it would be impossible for anyone to impart into the line of travel of the club head a new direction at, say, two feet from the ball, without ruining both the force and the direction of the ball. Therefore, it is evident that if one could close one's eyes when the club head was two feet from the ball and still keep one's head in exactly the same position, the impact would be practically not affected at all.
This is the undoubted fact in so far as regards the work of the eye. It fulfils its duty very early in the stroke; but although the explanation of the function of the eye is so incorrectly given, still "Keep your eye on the ball" is, and ever will be, a sound golfing maxim, for it is not given to golfing man to be able to lift his eye and at the same time to keep his mind concentrated on his stroke, and to keep his head in the same place as it was in when he addressed his ball. Therefore, although it is not so absolutely necessary to keep one's eye on the ball as is generally laid down, it is expedient to preach to the fullest extent and to insist on what Harry Vardon calls "the parrot cry of the links."
