You do realise your eye has an iris which works like the aperture

Sure do

Clearly not. The point is if a bright light is shone into your eye,
everything else becomes darker. The amount of light required to
attract your attention is an order of magnitude less than the amount
required to illuminate what's in front of you. That's why dipped
beam brightness of lights should only be used in the dark.

You are just being an ass. DRLs are not "shining in your eyes" in
daylight from half a mile away. They are headlights at half intensity.
They have virtually no effect on your eyes, as in "closing the iris" -

I do remember reading of some aircraft camo techniques experimented
with during WWII where forward facing lights were attached to the
wings causing the aircraft to blend in with the sky; seemed to be
somewhat effective during daylight bright skies.

Probably not much of an issue for DRL, however.

Since some stats show they increase safety and some show they decrease
safety, it looks rather like they have zero overall effect. So no point
in them! Perhaps we should concentrate on removing people from driving
who can't see a car in broad daylight without being helped out by lights.

You have to keep in mind where the DRL usage originated. Ever drove in
the prairies? One example, there is a stretch of 0ver 100 Km long
straight highway in Saskatchewan. Oncoming cars from distance are more
visible with DRL in the mirage.

There are three things you can see when you look ahead:
1) Clear road
2) Car
3) Not sure
If it's 3, don't overtake, it's not rocket science.
As for a long distance, just how long do you take to overtake? It doesn't matter how long the road is, you need the same length to overtake in Saskatchewan as anywhere else.
