But, yes I did it properly. I have many times so I do know what I'm doing. To be fair though, that is about the limit of my auto skills, apart from tyre pressures etc.
I don't mean any offense by this so please excuse me, but often times people think they understand aiming but they do not. I've seen far too many people online explain how they go about aiming and some are wacky and just plain wrong.
There is only one right way to set the aim. There is no in-between. And because you made this particular comment...
"If it bothers other people, no doubt I'll find out soon but at least I can drive with confidence again."
...this seems to imply that you performed a haphazardly adjustment. Because if they were aimed in the only correct way they should be aimed, they will NOT cause glare at all.
Your lamp centers are probably somewhere around 82cm from the ground (I'm using data from the VW Taos which shares same platform as Ateca). With the beam cutoff resting at the proper height, this puts the cutoff at 74.3cm from the ground. The average eye level for oncoming traffic is about 110 cm so as you can see, your cutoff is well below the level that would cause glare. You could probably lift your cutoff to 0.4 degrees down (which is the height applicable to U.S. lamps using your type of beam) and still be ok however I recommended the 0.57 degree aim as I don't know how strict your country is and if you are subject to inspections.
You may also want to verify your horizontal adjustment. Shifting the cutoff elbow to the right an inch or two would give you far better downroad illumination ASSUMING that your current horizontal aim has the cutoff elbow at the centerline of the lamp. If you look at the image below you'll see what I'm talking about.
Notice how the BEFORE has no light just under the red cross and slightly to the left? That area is the far end of your lane. Now look at the AFTER and you'll see how much better light coverage there is in your lane as well as some light carrying over to the opposite lane. This horizontal aim is a better choice IMO.
