They arrived promptly (from Glasses Direct or some such), and
I tried them all on for a test but have never actually worn any
of them since because even though they are frameless and
not particularly thick, they are heavier than my ReadySpecs
(so can fall off if working and I face downwards),

That's because you havent got the arm length right.

Is that something you specify when you order (in which case I would
have when did) or can adjust once you have them?

How do glasses with completely straight arms stay on peoples faces?

I generally have to bend or otherwise adjust the arms outwards to
reduce the pinching pressure on my head, even when that only results
in the arms ending up mostly parallel when fully opened.

I have known opticians adjust the arms for you. This are Glasses
Direct's own instructions:
