Take a small piece of paper & punch a tiny hole (≈1mm) in it with a pen. Look at RDS reticule through hole in paper. See the difference?
I was reading a bunch of old threads here & came across a few that described how an astigmatism makes the nicely shaped dot of an Aimpoint look like a comma, or a star, or fuzzy. I then remembered a bit of my photography lessons about the effect of aperture size on focus. So I tried the hole-in-paper trick & holy-moley, what a difference! Apparently I have an astigmatism. Never realized the Aimpoint dot is that crisp but it really is nice if you've got the eyes to see it with.
