I picked up my new glasses and I love them!
They are angular cat's eyes in a striped grey, with a pink interior. To me they are reminiscent of fish, in a good way, but this particular colour-way is called "grey tiger/pink". Doc C helped me to choose them, and he assures me they are interesting and fun, but not wacky. I do not want wacky. The plan now is that I can still use my older glasses (the lenses are only a little bit stronger in the new specs), so I have a choice of facial accessories depending on my mood/outfit/social obligations.
I also dropped off my favourite pair of shades to have prescription lenses fitted, so I'll actually be able to wear them again! Yay for shades!
