That's interesting as I was thinking on the low light goggle lenses I've got - they are pink, where all low light lenses used to be yellow.
Maybe I should try those over my driving glasses

Interesting, although they say:
I've not noticed that - in fact, for me they enhance contrast because they take out the blue light.Wossname wrote: ↑Mon Jan 22, 2024 12:07 pm I’ve tried a pair of those yellow tinted specs. They may reduce headlight glare, but they also reduce contrast, and that has the effect in the dark of making it more difficult to distinguish the difference between tarmac and verge on country roads, or kerb in urban areas, especially when there are approaching headlights. So not for me thanks.
Fair do's... none of us have exactly the same eyesight.
I was reading about the claims for yellow tinted specs for night driving yesterday. (I think it was in this months Which? magazine - I'll check later).

Overall, the opthalmic people said 'bad idea/no overall advantage' as they actually darken the dark areas.
I thought it was a bit strange, they go to great lengths to diss yellow tint specs in order to sell 'tinted' specs.Horse wrote: ↑Thu Jan 25, 2024 7:55 amSee the link I posted.Count Steer wrote: ↑Thu Jan 25, 2024 7:09 am I was reading about the claims for yellow tinted specs for night driving yesterday.

They're not saying that it REDUCED overall visibility or contrast sensitivity!Count Steer wrote: ↑Thu Jan 25, 2024 9:32 am study published in the journal "Optometry and Vision Science" found that yellow-tinted lenses reduced the discomforting glare from oncoming headlights but did not improve overall visibility or contrast sensitivity.

So if it had one positive effect and no negative effect, isn't that an overall positive??
Seems to be quite a small sample - 22 subjects - and an even smaller sub-sample of older drivers, 4 subjects. How reliable are the results, I wonder?Count Steer wrote: ↑Thu Jan 25, 2024 2:26 pm

Well, that's a dubious statement, even if the JAMA Ophthalmology journal is peer reviewed!Count Steer wrote: ↑Thu Jan 25, 2024 2:26 pm "You may want to tell your patients to ditch their yellow-lens night driving glasses. A study in JAMA Ophthalmology reports these tinted lenses don’t improve road visibility or diminish glare and halos, and may actually worsen visibility in some cases.
Whether a person is wearing yellow, red or blue lenses, they all cut out a portion of light, which basically equates to wearing sunglasses when driving at night, says lead study investigator Alex Hwang, PhD, professor at the Harvard Medical School Department of Ophthalmology.
There's something call 'Punjink Shift' ... or something ... for nighttime colour sensitivity.The Spin Doctor wrote: ↑Thu Jan 25, 2024 11:41 pm
Yes, they cut out light on the YELLOW WAVELENGTHS.
But we don't see all wavelengths with equal acuity. If I remember right, we're most sensitive to light in the green part of the spectrum during the day. I don't know about night-time vision.
