So. I was told today that my ongoing vision problems can be ameliorated with glasses. Apparently the problem is that my lenses are hardening, and so when I get tired the little muscles around them refuse to do their work, leaving me with blurry vision. The eye doctor thought it was funny, when he said "You seem to have trouble close up, does this get worse when you are tired" and I replied, "Yes, but I usually just take that as a sign that I should go to bed." I've gotten so used to having tired eyes, I'm really looking forward to the possibility of this being a less common thing!
