Never realized there is science behind why I shoot so much better w/ peep sights

I'll flat out admit I suck at using a notched and blade style iron sights. I have a hard time with the sight picture and getting everything lined up properly, especially with elevation of the shot more so than windage. I always though I was just better at lining up the post in the middle of a circle on an aperture sight. But there is a mot more science behind it then that.

Being a photography geek who knows quite a bit on how camera lenses work I never put two and two together that the aperture sight uses the same fundamentals as a camera lens to increase the depth of field in your sight picture as well as creating a parallax free sight picture. Yes your aperture sights are parralax free when you keep the front post away from the fuzzy edges of the ring in your sight picture. You can do a quick experiment if you have a peep sight equipped rifle to see how dramatically better the sight picture is looking through the aperture. Look through the aperture focusing on the post and anything far away will be clear and in focus, but lift your head slightly continuing to focus on the front sight but no longer looking through the aperture and down range becomes an out of focus blur. The science behind it is the same as a camera lens increasing depth of field by looking through a narrower aperture. This article explains it pretty well.

And this one is more scientific in looking at Parallax shift with aperture sights.
