Cursed as I am with hyper awareness of impending doom insomnia, I often skulk about my house in the darkness. I may have mentioned this before. In any case, as I haven't yet developed any kind of natural infravision, I still have to turn on lights if I want to read words on paper or do any kind of precision work with needles.
The dilemma here is that as I switch between lighted and unlighted activities in the deep of night, I am stricken with temporary blindness. When the lights go out, I have to sit and wait for my pupils to dilate before I venture to my next destination. If I don't, I almost always suffer the indignity of a stubbed toe or wake my wife unnecessarily with loud crashing sounds and strangled cries of pain. Not that she isn't used to that, but still. It seems rude.
I've developed a trick, though. One of these nights, after stubbing a toe, I found myself hobbling down the stairs to our living room in a decidedly peg-legged fashion, and it occurred to me that the two o'clock hour would be more entertaining if I spent it acting like a pirate. So I continued limping, wrenched one aye eye shut in a grimace and began muttering things like "Arrrh," "Avast," and "Scurvy dog." I kept this up through a bathroom escapade, a trip to the kitchen for a glass of water, and reading the last few pages of a Walking Dead graphic novel. Eventually, of course, my face got tired from holding my right eye shut, and I let it relax open as I started the pupil dilation period for the trip back upstairs.
What did I discover? Yes, my intrepid readers, from those long minutes of closure, my "pirate eye" had already become dark-adapted! There was no need to painstakingly wait for the other eye to adapt! I was able to dart up the stairs with perfect (well, half-perfect) night vision! No toe-stubbing, no unplanned strangled cries of pain. I've been using this technique for weeks now, and I'm very happy with it. Feel free to use it in your own homes. I do not condone use of Pirate Eye Nightvision for any illegal activity.
Appendix:
I am also developing a theory that this technique has long existed in the pirate captain community as a method of seeing possible attacking mutineers when coming below decks after a sunny stretch at the till. They flip up the eyepatch, and voila! Instant dark-vision. I mean, I've never seen anyone wearing an eyepatch in the dark, pirate or not. It makes sense to me. I mentioned this theory to my wife, and she seemed unimpressed with my reasoning, but I stand by it.
