A composition for disinfecting a contact lens comprising an effective disinfecting amount of hydrogen peroxide and a surfactant comprising a copolymer of hydrophobe and hydrophile blocks the structure: n HO-(hydrophobe) x -(hydrophile) y -(hydrophobe) x -H n or n HO-(hydrophile) y -(hydrophobe) x -(hydrophile) y -H n where x and y are integers reflecting the respective hydrophile and hydrophobe blocks of said copolymer; and the hydrophile component of the block copolymer constitutes less than 50 weight percent of the block copolymer. The block copolymer has a Ross-Miles foam height (ASTM designation D-1173-53; 0.1%, at 50° C.) of less than 1 mm. |
