Letter Re: Night Operations

Regarding Pete C.’s article on night operations: The great (but now sadly defunct) magazine “Coevolution Quarterly” had a great article about night vision development sometime in the 1980s (I’ve got a copy of it hanging around here somewhere, if only I was organized enough to lay my hands on it) that gave a brilliant method for training night sight via peripheral vision. The technique involved taking something like a lightweight brazing rod and attaching it [off-center] to the bill of a baseball cap. On the end of the rod, you attached a small white ball or disc, which you focused on as you walked. Finding a clear path on a moonless, lightless night, you put on the cap and focus on the ball/disc and begin walking. I tried this a couple of nights and though it took a while to really get the technique down, when you became adjusted to it, the effect easily rivaled that of artificial night vision devices. Apparently, with a bit of repeated practice, you can do away with the cap and fall right into the “de-focus” that allows or the ready use of peripheral vision for natural, intensified light gathering. Pete C’s article reminds me that I need to try this again, and get comfortable enough with it that I can do it at will. Regards, – Hawaiian K.
