Sunglasses do more than protect your vision. In poker, they prevent your opponents from seeing where you eyes are looking and can hide certain "tells". In golf, they can hide your feelings and emotions and elevate the intimidation factor. Probably no one used this more effectively than David Duval and his Oakleys.
But I realized something else about sunglasses when I was viewing coverage of Kyle Stanley's meltdown during last week's Farmers Insurance Open at Torrey Pines: sunglasses can change a person's appearance completely. When I viewed Kyle's official page on the PGA Tour website, I just about did a double take. Just compare the picture above to the one below from the PGA Tour website.
I swear that it's the same dude. He's like golf's version of Dr. Jekyll and Mr. Hyde! Let's hope that he can overcome his latest heartbreaking loss with a win soon. He deserves a win with his game.
