> How many people can you convince to wear glasses that do not normally?

It's fashionable (on the wane) at the moment. Lots of people are wearing frames with plain glass lenses.

> What about sun glasses? Will I need two pair of Googgles (2)? One for day, one for night?

The article covers this point - there will be a version that fits on existing glasses.

> Do you really think young women (or men) are going to wear these things?

Define young, and who cares? People with the money would, if there was a use. Link these to certain professions and I could see people deliberately, just as annoying students wear their lab coats out of the labs.
