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.
