• Not an argument, a discussion. Doesn't your first sentence contradict your second sentence, about the contrast and depth perception? Have some amber coloured cycling glasses that are useless but the yellow bolle (H&S, not fashion) glasses work well well while driving on unlit roads.

    This seems to agree that yellow glasses help blue light effecting sleep https://pubmed.ncbi.nlm.nih.gov/20030543/
    Know that it is one random group, but does bring up some interesting points.

  • Just going on my experience.

    Pros:

    • reduced harshness of glare

    Cons:

    • reduced vision

    My motorbike commute used to run the full gambit of roads so I didn't think it was worth having any reduction in vision. Also my clear visor has a photochromic pinlock which takes a bit of the edge of, but results in some distortion. However, that balances out as a net gaim whereas the glasses were a net loss.

  • full gambit of roads

    Gamut FYI.

  • It is good that we are having a discussion, personally I have never ridden a bike with yellow lenses, just proper safety glasses as I like riding with my visor open. So I want impact resistance as have had fashion glasses smash.

    Pinlock visor were an aid to stop misting for me.
