A few hours into Wednesday night's dark site session I began to wonder if others sometimes experienced what I was seeing - poor eyesight degrading the views. Shortly I realized my observing eye contact lens (semi-rigid gas permeable) had fallen out. That happens every year or so but had not been an observing issue. I'd long since stopped carrying a spare pair along on sessions. D'oh.
Having tried several times over the years to observe with my off eye didn't fill me with enthusiasm for the rest of the night's potential but exclusively using that eye actually worked out better than I feared. Averting vision to a different quadrant and, for some reason, maintaining the exit pupil in view were more difficult but it worked out in the end and the session's observations were not much effected.
I've been surprised more folks don't wear contact lenses to observe. Here's a reason for wearing glasses I recon.
