Their solution? A pair of trendy looking spectacles which claim to filter out this blue light.
You can get coatings for prescription specs that do that. I discovered the other day, when I looked for closely (sic) at the most recent prescription I was given, that the coating I have does filter out at least some blue light, and at least some UV light:

ZEISS DuraVision BlueProtect UV
The blue-violet light blocking coating from ZEISS.
DuraVision® BlueProtect UV is a coating specifically developed for customers who spend a lot of their time indoors and are exposed to blue-violet light from LEDs as well as TV, computer or tablet screens. ZEISS' blue light coatings for spectacle lenses block specific wavelengths of light, and can help to relieve the eyestrain perceived by the customers which is typically associated with blue light exposure.
Great, these manufacturers' claims, aren't they? How much independent testing's been done, I wonder? There were a few references in among the Essilor blurb, but they were a bit cryptic.
Having said that, some of the stuff in their leaflet that sounded like pure bullshit turns out to fit with my subjective experience. For example, "A lens engineered with artificial intelligence that knows how your eyes really move." "..seamless switch in focus from near to far..instant sharpness at all distances, even in motion". They are the best varifocals I've had, in about 15 years.
One issue is that the vehicles already sold, on the market or in the chain that will remain on the roads long after any legislative changes take effect.
But I can't see the UK making any unilateral changes.
Key Points
Question Are yellow-lens night-driving glasses associated with increases in nighttime road visibility and reductions in headlight glare from oncoming vehicles?
Findings In this cohort study of 22 individuals, yellow-lens night-driving glasses did not appear to improve pedestrian detection at night or reduce the negative association between headlight glare and pedestrian detection performance. A difference in detection with the yellow lenses was not noted based on pedestrian shirt color.
Meaning These findings do not appear to support having eye care professionals advise patients to use yellow-lens night-driving glasses.
I tried the yellow lens ” driving “ glasses and found no real improvement re glare but a significant reduction in contrast eg between road and verge. It was a distinct disadvantage to me (see what I did there?) - didn’t like them at all, tho they are heavily promoted in some publications.

Same as my experience about 60 years ago. They were crap then, and it seems crap now. Fools and their money, at least I learned from my mistake and didn't buy the recent reincarnation of the idea.
I've never had a problem with anything other than chav motors with HID / LED lamps in non-projector headlamps - modern headlights don't affect me however, the latest new Transit - WTF have they done there? Continually dazzled whether oncoming or from the rear - don't know what they have done but aim / pattern is shocking.

Tried them 20 years ago - made it difficult to see the surface of the road in the rain e.g. picking out manhole covers
