Woods was severely myopic; his eyesight had a rating of 11 diopters. In order to correct this problem, he underwent successful laser eye surgery in 1999, and he immediately resumed winning tour events. (He received money from TLC Laser Eye Centers to endorse them, In 2007, his vision again began to deteriorate, and he underwent laser eye surgery a second time.)
Early in Woods' career, a small number of golf industry analysts expressed concern about his impact on the competitiveness of the game and the public appeal of professional golf. Sportswriter Bill Lyon of Knight Ridder asked in a column, "Isn't Tiger Woods actually bad for golf?" (though Lyon ultimately concluded that he was not). At first, some pundits feared that Woods would drive the spirit of competition out of the game of golf by making existing courses obsolete and relegating opponents to simply competing for second place each week.
