Quote History Quoted:Don't envy me my eyesight as it's poor. However, using a small target aperture up close to one's eye dramatically increases the clarity of your vision, even if it's poor like mine because of an optical principle called Depth of Field (DoF). I'm far sighted, with astigmatisms, and almost legally blind without my glasses.
That said, the DoF increase when using a small aperture held close to one's eye is astounding. So much so that I also use another, free method of allowing me to shoot any iron sighted rifle or pistol with a clear view of both the front sight and the target, no matter the range.

Try it yourself right now by curling your index finger around in a tight circle so the tip touches your palm. In the gap between your first joint and knuckle you should have a tiny hole. Put your eye up to your hand and sight through it to see how clear your vision is.
That's DoF at work. Then make yourself one of the tape apertures and apply it to your shooting glasses. It's free and I'll bet you are astounded by the clarity of your sight through the aperture.

That's good advice, COSteve. I've been all over modifying OEM rear sights for installation of replaceable rear sight apertures which have very small ID apertures for years. I even have an ancient, Brit-made OEM rig for my M1917 rifle that allows precise aperture movement, and a very interesting camera-type adjustable rear aperture. Bought it cheap long ago. Probably unobtanium now.
I concur on apertures mounted on shooting glasses being of value, and one can make them (as you suggest), or buy expensive, adjustable ones.
As for myself, I incline to more of a "tactical' viewpoint, where such aids might
not be available. More to the point, wider-view optics, such as RDS and others, just might be far more useful for "Practical/Tactical" purposes than a rig that is ideal for the target range.
Now, I defer to your experience on the range, and having read it, find
nothing with which to disagree.
However, other users might have different goals, and different abilities; I think it's worthwhile to acknowledge that goals can vary, and the means of obtaining those different goals can also vary, depending on the skill and experience of the user.
I DO consider you to be an informed individual. Any possible differences between us are probably trivial, and could be settled over a single beer.
I respect what you have done, and what you have posted.
