I think I forgot to mention this, but I got glasses that I actually wear every day. I've been nearsighted for ages and every few years I'd get an eye exam and a new pair of glasses and they'd give me headaches for a couple of days and then I'd stop wearing them except for at the movies.
But a month or so ago I read a blog post at Black Girl Lost Keys about vertical heterophoria and that, coupled with issues seeing detail work up close, convinced me to go in for an optometry appointment and ask a lot of questions. I was lucky, I got a great optometrist who was already familiar with it, and yeah, turns out my eyes are slightly misaligned. My new glasses are progressives so I can work up close, but more importantly they have a slight prism built into the lenses to correct for the misalignment.
They were by far the most expensive lenses I've ever gotten, and I was worried I'd dump them just like I dumped all the others, but I put them on and it was like magic. No headache. I notice when I forget to put them on in the morning. I don't notice myself holding my neck at that weird angle anymore, and there's a marked decrease in walking into corners. It's pretty amazing.
But it means I'm getting used to things about wearing glasses I never thought about before. Today I picked up a copy of A Psalm For The Wild-Built at the library sale and I read it over the afternoon and I cried near the end and then I realized I'd gotten little speckled tear marks all over the lens. Oops.
Reading actually felt better too. I can't remember the last time I didn't have to set down a book after a little bit because my head hurt. I guess it had been bothering me more than I realized. One more reason to be glad I got them, I guess.
