Query: Comfortable but not functional for shop work

I bought these glasses for my husband to use in the factory he works at to protect his eyes. While they are comfortable to wear he found that he kept having to wipe the lenses off and eventually just took them off because they were getting foggy from his breathing normally. There is no reason for that to happen. The shop stays at about 60 degrees in the winter so the normal breathing action should not have caused this. Having to find different glasses for safety since these became more of a hazard in real life setting.
