Searching for answers to his extended slump, Braves right fielder Jeff Francoeur was fitted Monday for a single contact lens for his right eye.

His vision in the eye has deteriorated since Francoeur was struck in the face by a pitch while squaring to bunt in a 2004 minor league game, and he thinks it might be a cause for the wide gap between his offensive statistics in day and night games.

He hit just .207 with three homers and a .323 slugging percentage in 50 night games before Monday, and .320 with five homers and a .553 slugging percentage in 26 day games.

"We'll see what happens," said Francoeur, who wore the contact lens in Monday night's series opener against Milwaukee. "I'm near-sighted in my right eye a little since I had surgery [for multiple fractures of his right cheek and orbital bone around the eye].

"I'm not making excuses, but I feel like I haven't been able to recognize pitches. I've only got to wear it at night."

The right-handed batter said he's not been able to pick up the rotation on pitches during night games.

If the vision is causing problems in night games, it's a recent development. Last season he hit better at night — .301 with 16 homers and a .466 slugging percentage in 116 night games, and .273 with three homers and a .390 slugging percentage in day games.

Francoeur conceded that he's willing to try just about anything to get out of his slump. He had a .236 average with five homers and a .297 on-base percentage in his past 65 games before Monday, and a .215 average in his past 28 games.

"It's been tough, but I try to stay positive," he said. "There's so much of the season left. We can really take off. They need me to do what I've done the last two seasons."
