The purpose of the present invention is to provide a technique for preventing the adsorption of pranoprofen and/or a salt thereof onto a soft contact lens (SCL) in an ophthalmic composition for SCL, said ophthalmic composition comprising pranoprofen and/or a salt thereof. In an ophthalmic composition for SCL that comprises pranoprofen and/or a salt thereof, the adsorption of pranoprofen and/or a salt thereof onto SCL can be effectively prevented by regulating the equivalent of cations other than hydrogen ion to 140 mEq/L or lower.本發明之目的為提供一種技術,其係在含有普拉洛芬及/或其鹽的SCL用眼科用組成物中,抑制普拉洛芬及/或其鹽吸附至SCL。本發明藉由將含有普拉洛芬及/或其鹽的SCL用眼科用組成物中氫離子以外的陽離子當量設定在140mEq/L以下,能夠有效地抑制普拉洛芬及/或其鹽吸附至SCL。
