An agent for contact lenses, comprising chloroacetamide. According to the present invention, chloroacetamide, which is the bacteriocidal component to be contained, is scarcely adsorbed not only to hard contact lenses and gas-permeable hard contact lenses, but also to soft contact lenses, and even if adsorbed, moreover, chloroacetamide is quickly released and is not accumulated on the contact lens to a greater extent. The inventive agent containing, in addition to chloroacetamide, sodium lauryl sulfate shows more superior bacteriocidal effect and cleaning effect. Therefore, the present invention provides an agent for contact lenses having superior bacteriocidal effect and cleaning effect, which can be used safely and with ease for various contact lenses inclusive of soft contact lenses.

Agent pour lentilles cornéennes comprenant du chloro-acétamide. Selon l'invention, le chloro-acétamide, qui est un composé bactéricide à contenir, est très peu adsorbé non seulement par les lentilles cornéennes dures et les lentilles cornéennes dures perméables aux gaz, mais aussi par les lentilles cornéennes souples. Même si le chloro-acétamide est adsorbé, il est libéré rapidement et ne s'accumule pas en grande mesure sur les lentilles cornéennes. L'agent visé par l'invention qui contient, en plus du chloro-acétamide, du laurylsulfate de sodium présente un meilleur effet bactéricide et donne un meilleur nettoyage. L'invention offre donc un agent pour lentilles cornéennes, dont l'effet bactéricide et le nettoyage sont supérieurs, qui peut être utilisé facilement en toute sécurité avec différentes lentilles cornéennes, y compris les lentilles souples.
