The purpose of the present invention is to provide a technique for achieving a clear appearance in an ophthalmic composition which is for a zwitterionic soft contact lens (SCL) and which contains pranoprofen and/or a salt thereof and inhibiting the pranoprofen and/or the salt thereof from being adsorbed on the SCL. The technique includes: adding chondroithin sulfate and/or a salt thereof to an ophthalmic composition which is for a zwitterionic SCL and which contains pranoprofen and/or a salt thereof and adjusting the pH of the composition to 5.5 or higher. The technique can achieve a clear appearance in the ophthalmic composition and effectively inhibit the pranoprofen and/or the salt thereof from being adsorbed on the SCL.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SCL用眼科用組成物呈現澄清透明的外觀性狀,且抑制普拉洛芬及/或其鹽吸附於兩性離子性SCL。藉由在含有普拉洛芬及/或其鹽的兩性離子性SCL用眼科用組成物中摻合硫酸軟骨素酯及/或其鹽,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SCL。
