I'm coke-bottle nearsighted too! One reason I stopped wearing contacts, in addition to them irritating my eyes more the older I got, but my prescription is so strong and complicated (I've got myopia AND astigmatism) that they could never get it tight enough for me to see crisply. I have much better vision with my glasses.

I adore that he insisted on the Doctor wearing glasses at least some times, since he was plagued with glasses as a child and wanted speccy kids to have a hero to look up to who also needs specs.
