As for this problem to be solved by the invention, at the time of the sterilization processing of the contact lens which uses the hydrogen peroxide water simply the catalyst for new contact lens sterilization which can verify catalytic action circumstance there are times when the device and the method of using that are offered. In order to solve this topic, the catalyst 14 for contact lens sterilization which is soaked in the liquid of hydrogen peroxide water 44 inside container 10 for sterilization of contact lens tried to displace and to stop, during disassembly reacting of hydrogen peroxide water 44 the buoyancy which is based on the oxygen air bubble which occurs causing, although it displaces after the disassembly reaction of hydrogen peroxide water 44 the buoyancy which is based on the oxygen air bubble disappearing.本発明が解決しようとする課題は、過酸化水素水を用いたコンタクトレンズの殺菌処理に際しての触媒作用状況を簡易に確認することができる新規なコンタクトレンズ殺菌用触媒とそれを用いた装置や方法を提供することにある。かかる課題を解決するために、コンタクトレンズの殺菌用容器10内の過酸化水素水44の液中に浸漬されたコンタクトレンズ殺菌用触媒14が、過酸化水素水44の分解反応中は発生する酸素気泡に基づく浮力が及ぼされて変位する一方、過酸化水素水44の分解反応後は酸素気泡に基づく浮力が消失して変位停止するようにした。
