In my country, the number of Covid 19 new cases is growing very fast, so we need to wear masks outside too. Here comes my problem. I wear prescription glasses, and as the weather is getting cold, they get foggy very fast. I tried all kind of masks but it doesn't make much difference. I tried higher masks too, and put glasses over the mask, but it's still happening. Do you have any tricks or suggestions for me? Thanks in advance.
