AI Thread Summary
The discussion revolves around a technique for enhancing night vision by temporarily covering one eye, which some participants find amusing yet familiar. It highlights the concept of dark adaptation, where one eye adjusts to darkness while the other remains uncovered, potentially improving night vision. Participants question the uniqueness of this method compared to simply sitting in a dark room, noting that the perception of darkness may be skewed. There is a humorous tone regarding the potential discomfort of the technique, with some contributors reflecting on their past experiences learning similar tricks. Overall, the conversation blends nostalgia with skepticism about the effectiveness of the method.

Ooh, that's so cool, it's scary!

PS : You can still be productive with just the one eye.
 
Umm, so have anyone tried it yet?
 
I would say old and obvious, but that might just be me.
 
Actually, this little trick explains a lot why you can see the stars in the night sky (as long as the clouds are not fussing about).

These were the things you learned in cub scouts, back when kids were cub scouts. By the time I was in sixth grade, I had learned about this trick half a dozen times. But that might just be me.
 
Um, wow. Dark adaptation. Stop the presses!

So how is this different from sitting in a dark room for 20 minutes?
 
The amount that your eyes adjust becomes pronounced.

I think the effect is more pronounced because you are determining how dark it is according to the uncovered eye (which will think "merely dim" is "complete darkness"). You will still see even better in the dark when you wake up at night.

THIS JUST IN! GIVE YOURSELF TEMPORARY BLINDNESS AND SEVERE OCULAR PAIN!

Just shut both your eyes for 20 minutes, and then open them while simultaneously turning on every 120 watt light bulb around!

AMAZING!

Must be. Most of us just have to learn something once.
