Purpose: To investigate the proper care system of sample-wearing cosmetic contact lens (SWCCL). Methods: Research on the actual condition about SWCCL was examined in fifty cosmetic contact lens wearer in their 10s and 20s by the questionnaire. Also, the extents of the contamination of gram-negative bacteria and fungi were measured in SWCCL after wearing for 2, 4 and 6 weeks, and it was investigated whether the proper care system could prevented the contamination. Results: As the result of the questionnaire, people purchased the cosmetic contact lens after trying SWCCL with a mean of 4.5. The contamination of gram-negative bacteria and fungi were significantly increased in SWCCL-wearing period-dependent manner. In both Group 1 (rubbing SWCCL and exchanging preserving solution every wearing of SWCCL) and Group 2 (only exchanging preserving solution every wearing of SWCCL without rubbing SWCCL), the contamination of gram-negative bacteria and fungi were prevented perfectly. In the case of Groups having every-week care, the proliferation of gram-negative bacteria and fungi were somewhat suppressed, and rubbing was helpful of decreasing the contamination. The biweekly care had scarcely any effect for preventing the contamination. Conclusions: By exchanging the preserving solution every wearing of SWCCL, the contamination of gram-negative bacteria and fungi could be suppressed perfectly.
