When I was young I had an indiglo watch. Naturally, I pushed the indiglo button and shined it directly into my eye.

I happened to notice at night that by opening one eye while simultaneously shining the indiglo into the other eye, it seemed to give me a slightly better view in the dark.

Now, try this at your own risk.

What do you think? A minimal at best increase in detail?
