I was surprised to see Padraig Harrington wearing glasses at the Valero. I tried to wear glasses while playing golf for 3-4 years and then stopped the practice after I forgot them one day and played 5+ shots better than I had been playing. I found they affected my swing as the ball always seemed to be close to my knees. I also had a minor distortion with my peripheral vision as I prepared to putt.
Padraig and his optometrist must have had a premonition that this change could hurt his career as they prepared seven pairs of glasses with different frames and lenses for his first tournament. When interviewed, Padraig said, "These glasses are pair number five. I also have [numbers] six and seven with me this week. They're all different frames and lenses. These are a little bit shorter and the *** is a bit long, but they seem to be winning."
