As the old baseball adage goes, keep your eye on the ball -- especially if your eyes are blue.
A recent ABC News report looks into the increasingly apparent discrepancy between blue-eyed batting averages at day games and those same batting averages at night.
Case in point: former American League MVP and blue-eyed star Josh Hamilton, who hit a whopping 100 points worse at day games during his incredible 2010 season.
"Try to go up [to the plate] squinting and see a white ball while the sun is shining right off the plate, you know, and beaming right up in your face," the slugger says. "I ask guys all the time. Guys with blue eyes, brown eyes, whatever ... and guys with blue eyes have a tough time."
According to researchers, blue or light colored eyes, which have lower density pigment at the back, are less adept at filtering the sun's glare.
So Hamilton is looking for a remedy. The Texas Rangers star has tried sunglasses and ever a set of contact lenses which make his eyes appear red and are designed to help with the glare. (Take a close look at the image above.)
"I've never worn contact lenses in my life and I really would like to see the ball in the daytime, so therefore I'm trying any means possible to do that," Hamilton told ESPN. "I actually care and I want to be better and I don't want to suck in the day."
