Does changing the distance of your eye to the red dot have any effect on degree of paralax error. Example: 14 inches to my eye vs 6 inches to my eye shooting at 25 - 30 yards. Does an off center dot have more effect one way or the other? Tks.

Distance (rye relief) doesn’t cause parallax error. Parallax error deals only with the X and Y dimensions. When in doubt, bob your head around and see if the dot appears to move against the target.

Does eye relief effect the amount or degree of paralax error when you do move your head around? With an off center dot, is the shot farther from the bulls eye with longer eye relief, or the same?

i dont know the facts around red dots, all i can tell you is i set eye relief so i can get on a target the fastest bringing the gun up to my natural hold and cheek weld with both eyes open .. your head shouldnt be 'bobbing' around trying to find the target and it shouldnt seem like the scope itself is 'in the way' .. just put it in the most natural spot man , itl be alright lol ..

Hello Most good red dots are parallax free and the location on the gun or the angle you look threw them will not change your point of impact. But on some lower price /quality red dots they have a set parallax so if you change the angle you look threw the sight you will change the point of impact. Hope this helps Eric

Apparently, there is no such thing as a parallax free red dot and its seems to vary from person to person. You may have to just test it for yourself.
I find the closer to the dot my eyes are, the more blurry the dot is.

Thanks for the refrence. Quite an indepth and interesting test. I read the entire report, and to my amazement as you have stated, there are various amounts of paralax, even from the best companies out there, and it's not linear with distance. Your last statement touches directly on the point I had in mind.
For my eyes (post cataract & multi focal lense implant) there is a specific shorter eye relief that yeilds a slightly better image. Considering the "price range" and quality of the red dots I use (lower end) it seems that keeping the dot centered in a reproducable fashion is the paramount issue.
However this report has sparked my curosity, and I am going to do some POI tests at different positions within the feild of view of my red dots. My typical range (post cataract) is 25 yards or less. I plan on making 9 dots with a marker on my lense going about half way to the edges. No reason to test extremes. And see how much the POI changes compared to center alignment. I suspect it will be minimal but interesting. Thanks for your input, always appreciated.
