1. I've always heard that if you frequently use your lenses, then the exposure to outdoor light will be enough to kill any fungi or spores that could develop if you left your lenses in the dark or indoors. 2. The statements from you guys are saying UV light is filtered by the glass elements except for a small band width, and that band width has no effect on fungus growth. There is a discrepancy between the theories of these two assumptions. Does anyone have any documented scientific evidence on lens use/lens exposure to outdoor light and fungus growth?
