Do You Put Your Eyeglasses In A Case When Not Wearing Them?

At home, they're often left on the table, upright; not face down on the lenses...but there are no cats to knock them off.
Out of the house, I have both clear and polarized sunglasses. Whichever's not on my face is usually in a hard case.
Once upon a time, I was on a long drive home, arriving well past midnight. I thought my Rx sunglasses were in the cup holder; they weren't. They'd been under my boots all night.
