Riddle me this…

I have mismatched eyes. One pupil, when in dim light, is larger than the other. I was born that way. I am sure if I’m ever in a car accident where I am unconscious, they will look at my eyes and go “uh-oh, brain damage.”

The other way in which they are mismatched is the prescription. One is fairly good, though no longer perfect. The other is fairly bad, but not so bad that I couldn’t legally drive with a patch over my good eye. It is an odd eye with something like an astigmatism, though the doctors have always been fairly vague about it, like they’re not sure. They can’t fix it with lenses, though they can make it better a bit. My most recent doctor mentioned that there’s probably some atrophy of the nerves back there, that part of the vision problem is that my brain has forgotten how to process stuff from that eye. Odds are, she said, I should have had a patch growing up, to strengthen the weak eye. But the thing is, I had 20/20 vision until my senior year in high school, when I noticed that things on a stage several hundred feet away looked a wee bit blurry out of the right eye. When I tell them that, they just go hmmph and hand me my bill.

But that’s just background. The riddle is this: a few months ago, I started getting headaches and wooziness, usually after reading or looking at a computer monitor for extended periods. I have had this reaction before, and it means it’s time to get a new prescription. However, I had had one not so long before, 6 months, maybe more. I usually go a couple years between prescriptions.

This time, I got a new prescription, but the difference was slight, and I was still getting headaches and dizzy spells.

Except one day I left my glasses at home accidentally, and no headaches or dizzy spells.

I’ve had them off for most of a week now, and I’ve been fine.

I’ve never really needed the glasses to see, I’ve always worn them to avoid getting headaches, which is what used to happen when I didn’t wear glasses.

I don’t get it. I guess I’ll just learn braille and be done with the whole business.
