I've been having trouble focussing my eyes for the past week. Turns out I have some kind of macular dystrophy. My right eye has a blurred and displaced area (about the size of my thumbnail at a range of 30cm) which makes bits of text bend and blur when I try to look directly at them. My left eye is fine but seems unwilling to help my right eye out - presumably after years of laziness.
Apparently I'm too young for it to be conventional macular degeneration. I think that's supposed to be a consolation of some sort. It's all a bit freaky given that I spend about 80% of my waking time staring at a screen. Can't do that right now for more than about half an hour without getting a headache.
The good news is that it happened once before about five years ago and either went away or my brain got used to processing the distorted image. This in spite of having been told it was both incurable and degenerative. Of course right now I'm using the eye-power I have reading whatever I can find about the condition.
So I guess I might be a little less always-on than usual. The effect is much less pronounced when I focus near infinity. That's an excuse to get out more if ever I heard one.
