The purpose of the present invention is to provide an ophthalmic composition for a zwitterionic soft contact lens that includes pranoprofen and/or a salt thereof, wherein the external appearance is clear, and adsorption to the zwitterionic soft contact lens including pranoprofen and/or a salt thereof is suppressed. An ophthalmic composition for a zwitterionic soft contact lens that includes pranoprofen and/or a salt thereof, wherein trometamol is combined, a clear external appearance can be achieved by setting the pH at 5.5 or more, and adsorption to the zwitterionic soft contact lens including pranoprofen and/or a salt thereof can be effectively suppressed.本發明之目的為提供一種技術,其係使含有普拉洛芬及/或其鹽的兩性離子性軟式隱形眼鏡用眼科用組成物呈現澄清透明的外觀性狀,並且抑制普拉洛芬及/或其鹽吸附於兩性離子性軟式隱形眼鏡。藉由在含有普拉洛芬及/或其鹽的兩性離子性軟式隱形眼鏡用眼科用組成物中摻合胺基丁三醇,並且將pH設定在5.5以上,可實現澄清透明的外觀性狀,而且可有效抑制普拉洛芬及/或其鹽吸附於兩性離子性軟式隱形眼鏡。
