Luckily, the lens I lost was the lens for my good eye. Or, more precisely, my less bad one. My left eye has always needed a powerful prescription, but until a few years ago, the right lens was just plain glass. But recently I developed myopia in the right eye to complement the amblyopia in the left. Or is it farsightedness? I don't know. Whatever it is, it's pretty mild, so my vision is really not at all hampered by not having the corrective lens over that eye.
I have an eye appointment this afternoon, and I should have new glasses before the end of the day. Fun!
