Kenny Perry is having vision problems that make it difficult for him to read greens or see clearly from long distances and shady spots.
Yet, Perry is so comfortable playing at the Colonial that he's still in the lead by three strokes with a tournament-record score after two rounds.
''I know the greens. I don't really have to see that well," Perry said. ''I know what's uphill, what's downhill. I know the breaks, I pretty much know where the pin placements are going to be. So that's very comforting."
Perry had a bogey-free 7-under-par 63 yesterday, his best round of the year.
His 12-under 128 set the 36-hole scoring record at Colonial, where Perry also holds the overall scoring record of 19 under for his 2003 victory. His two-round score beat the previous mark of 11 under, shared by four players.
''Things have gone my way. I understand how to play here," said Perry, playing at Hogan's Alley in Fort Worth for the 16th time. ''I just feel very relaxed and very comfortable when I play here."
Perry plans to visit an eye doctor next week, and expects to be wearing glasses when he tees off for the next PGA Tour event in Memphis.
D.J. Trahan (67) and Ted Purdy (65), whose first Tour victory came last week at the Byron Nelson Championship, were tied for second at 9 under.
First-round leader Patrick Sheehan was 10 strokes worse yesterday, a 72 following a 62 that gave him a two-stroke lead. Sheehan goes into the weekend six strokes back, tied for eighth.
Champions -- Dana Quigley of Rehoboth tied a Tour record with eight consecutive birdies in a 7-under 65, and held the lead in the rain-delayed Bruno's Memorial Classic in Hoover, Ala.
Shortly after Quigley completed his round, thunderstorms moved into the area, ending play for the day. The first round will resume this morning when 42 of the 78 players will finish their rounds. Second-round play will follow.
Quigley's string of birdies matched the Tour record set by Chi Chi Rodriguez in 1987 and matched by Jim Colbert five years ago.
Quigley had the opportunity to birdie every hole on the back nine and break the record on the par-5 18th hole, but three-putted for bogey.
Tom Wargo is one stroke back.
LPGA -- Paula Creamer and Joo Mi Kim, the leading rookies on the Tour, were among four players tied for the lead after two rounds of the

Creamer, who is 18 years old and 19th on the Tour's money list, had a 3-under 68. She graduates from high school next Thursday in Bradenton, Fla.
Creamer, who finished second at the Shop-Rite Classic last year as an amateur, has two top-10 finishes this year. She won 11 amateur tournaments.
Joo Mi Kim, 20, who is 49th on the money list, had a 65 to match the low round of the tournament. The native of South Korea has three international victories.
NCAA Women -- Anna Grzebien, a sophomore from Narragansett, R.I., led Duke to its third NCAA Division 1 title in seven years, closing with a 2-over 73 for a one-stroke victory in the individual competition.
Grzebien, who shot a tournament-best 65 Thursday to help top-ranked Duke take an eight-stroke lead into the final round, finished with a 2-over 286 total on the Sunriver (Ore.) Resort's Meadows course.
Duke shot a 13-over 297 in the final round to finish at 34-over 1,170, five strokes ahead of 2004 winner UCLA.
