Paper Pinhole Glasses

I recently learned that by poking a hole in a piece of paper, I can improve my vision when looking through it without my glasses. It's similar to a pinhole camera, where I control how light enters my eye. Surprisingly, this method allows me to see objects, especially text, much more clearly than I could without my glasses. It might come in handy if you lose your glasses.

I noticed this too with my microphone shockmount

It's interesting where this shows up! Pinhole cameras are probably the most commonly known. And I was just searching and found these: en.wikipedia.org/wiki/Pinhole_glasses Never heard of that before.

Glass paper ??

That’s what they use for iron sights

That is interesting, I did not know that. Looking online it seems there is a front sight and a rear sight. Lots of physics going on there!
