Night driving....
I ask as an optician, wondering whether to punt these things to
people who complain about such....
Has anyone got any specialised night driving lenses?
Hoya En Route for example, or Zeiss Drivesafe.
I don't actively sell them as they are damned expensive and the
feedback I have heard is mixed at best.
Maybe this will help you decide:

I guess it all comes down to subjectivity. Perhaps your particular
visual capabilities are helped and the same doesn't apply globally.
I've never tried amber night driving specs as my specs cost enough
already. I probably am unaware of how lights appear to people with
perfect unassisted vision.
FWIW, I have never seen the milky way in all it's glory other than in
photos due to the simple fact that the smaller points of light are not
visible with my prescription.
Hard to miss from somewhere like the Canaries. My astigmatism doubles
point sources at night.
You can get glasses for astigmatism.

intellectuals to believe it, but the power that it confers on
intellectuals, in their attempts to control the world. And since...it is
futile to reason someone out of a thing that he was not reasoned into,
we can conclude that Marxism owes its remarkable power to survive every
criticism to the fact that it is not a truth-directed but a
power-directed system of thought.€ť
