This helps?

I don’t know if those things have size… length? Girth? Both?

Seriously, I wanna know. Is it size? Or… flow?

I don’t like this “smart glasses are evil” sentiment. They would improve the lives of many people. I’ve seen demonstrations of its use for blind people. Even people simply travelling and having everything translated automatically would be nice. But, yeah, going into a restroom with them on, or not asking for authorization from the patient to use them, crosses a big red line.
