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:<paragraph lvl="0"><in-line-formula>HO-(hydrophobe)x-(hydrophile)y-(hydrophobe)x-H</in-line-formula><paragraph lvl="0"><in-line-formula>or</in-line-formula><paragraph lvl="0"><in-line-formula>HO-(hydrophile)y-(hydrophobe)x-(hydrophile)y-H</in-line-formula>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.
