For those of you who wear contacts and/or glasses:do you wear just one or the other all the time, or do you rotate between methods of vision correction?

If you sometimes wear glasses and at other times wear contacts, what leads you to choose one method over the other?
Do you feel that one option is more stylish/more formal/more casual/easier/more "lazy" than the other?

For extra credit, explain your reasoning.

This post was inspired by a conversation with an optician a few weeks ago, while picking up my new specs. He mentioned that he thinks of glasses as "face jewelry with a prescription" (I may be paraphrasing a bit), a description that I loved.

I'll answer my own question below.
