Fortunately, all the worrying was for nothing; my eyes are in good health (aside from my staggeringly low diopter, but hey, them's the breaks). So, the upshot is that I'm getting a new prescription and new frames for my glasses as well. Which is good, because I dare say my new glasses will be more flattering to my face. Plus, you know, I'll be able to see better.
If you'd like to see a picture of me with the new frames, it can be found here.
... ... Oh yeah, and Happy New Year to everybody!
