症を起こすことがある。As the disinfecting solution, a hydrogen peroxide solution or a chlorine-based disinfecting solution is often used, and in each case, a solution prepared by mixing / diluting a drug or adjusting in advance is used.
In the case of chemicals to be mixed / diluted, the mixing ratio / concentration of the resulting disinfectant tends to vary due to amateur processing. Also, the concentration of a pre-adjusted drug is low, and depending on the storage condition, the drug effect may be significantly lost. Most drugs also require neutralization after disinfection. However, there are many cases in which neutralization and washing cannot be performed well, and as a result, eyes or eyes may be irritated if the constitution is sensitive to drugs.

The contact of 10b is broken. As the negative electrode 10a, a carbon fiber obtained by electrolytically polymerizing polyaniline is used. The negative electrode 10a may be a material obtained by applying polyaniline kneaded with epoxy to carbon fiber. Platinum is used for the positive electrode 10b, and a DC voltage of, for example, about 1V to several volts by the battery 12 is applied to the electrodes 10a and 10b.

ついた消毒液を用いる不都合が回避できる。As described above, according to the present invention, the contact lens is disinfected by the bactericidal effect of continuously generated active oxygen. Moreover, for this purpose, it is only necessary to prepare a liquid in which oxygen is dissolved in a container, put an electrode carrying polyaniline on a negative electrode and a general electrode for electrolysis into the container, and apply a DC voltage thereto. The possibility of accidents or failures due to the heating with which the disinfection was inherent can be avoided. The active oxygen generated in this way has a very strong bactericidal effect,
Since its life is generally several seconds and quickly disappears, there is no need to perform neutralization after disinfection as in the conventional chemical disinfection. Therefore, it is possible to avoid inconvenience such as pain in the eyes due to a lens that has not been successfully neutralized. In addition, it is needless to say that preparations such as mixing / dilution of chemicals are not required, and the inconvenience of using a disinfectant having a different mixing ratio / concentration can be avoided.
