First, welcome in.
Second, you see the language sensors already caught something.

I have both types of mirrors, and use the commercially available protective sheets that are designed to protect smart phone screens (specifically iPhone) on all my mirrors.

I have yet to have one scratch, but I have broken a glass mirror in a fit of clumsiness.
