For those whose eyesight is still good enough to let them use dots, this appears to be good advice.
I personally have almost completely switched to LPVO & 1X prism sights due to the degenerative effects of age and the capability of adjustable focus eyepieces to compensate.
As it is, the Steiner and  Vortex LPVOs I have are of a size that co-witness of back-up iron sights is impossible, but I do have one AR ‘pistol’ with a prism sight that I will have to check out to see if this effect occurs.
