Do you wear glasses or know someone who does? Most of us have plastic lenses with an anti-scratch coating. It works pretty well.

What advantage would there be to switch from plastic lenses for practical items like glasses to glass lenses with a thin soft plastic coating?

I don't, and the couple people I'm close to that do have glass lenses. But, my sample size is pretty bad.

I legitimately didn't know it was that common; I had to switch to glass lens non-prescription sunglasses a few years ago because even the upper end plastic ones weren't durable enough for me.
