    Question Why tint for night driving ?

    I know people want tints for night driving. Mainly yellow. WHY!!! I am of the opinion and impression that ANY tint at all will ultimately dull visibility. Am I not correct in this? If I am not, then tell me why exactly yellow is so great and will increase and decrease visibility at night? I need to know more on this subject after all these years.

    :angry:

    Yellow tint mainly to enhance the contrast.. to be precise, it is not advice to use it at normal night driving.. depend on the environment condition.. use it during foggy condition will surely help due to the poor contrast environment causing by the fog. drive at night on the well lighten up city street is really a bad idea to use the yellow tint.

    ANY tint will DECREASE contrast sensitivity.

    Particularly in low light.

    PERIOD.

    It is generally NOT adviseable - so you are thinking correctly.


    Ian on the boards here is a good one to chat with if you're looking for good info on tinting etc.

    Anti glare lenses are FAR better for accurate transmission of light, and proper focus of the ray pattern - possibly the greatest reason for *perceived* glare...unfocused light rays.

    Best of luck! :cheers:

    Yeap -1/2. Yellow filters do not increase contrast under ANY conditions.

    Yeah, it's like prescribing a plano/w AR for night driving. :hammer::hammer:

    Its really the eyes

    While 'tis true that any tint will decrease the available light, that doesn't take peoples' psychology into effect. We know that a lens in yellow will highlight the peak of the eye's spectral response curve. It will also decrease the amount of blue light that is bouncing around our visual targets and periphery, reducing this glare component. When we are younger this is fairly unimportant. But when we are dealling with the geriatric crowd this becomes more of an issue. It is probable that a very light tint in yellow will help these drivers on urban roads (basically where they mostly live, anyway) by icreasing their contrast sensitivity. Of course, any tint used at night on rural, unlit roads is a no-no! The major help for all of our patients, young and old, is to make sure that the inside of the windshield is ablolutely, spotlessly clean and streak free.

    I've had tint on all of my cars, and have noticed no difference in my ability to drive at night. You can wear special driving glasses while retaining the night driving use of both eyes.

    Tinted windshields are never tinted in a drivers line of sight! ANY tint on a spectacle lens reduces the amount of light able to pass through the lens. Obviously this does not refer to AR treated lenses which let in more light than untreated clear lenses.

    I am reminded of the notice I received last year from the USGA regarding a new "Leaf" rule for lost golf balls during the fall season. (For those of you who may not be aware, your golf ball can become lost in or under the leaves) Anyway, the USGA provided a link to the page containing the "new leaf rule". When you clicked on it, you got the message

    "There is no leaf rule"

    I say the same thing about tinted lenses for night driving.

    There is no tint for night driving!

    I wish they had not forgotten to also make a bedroom rule, where these golf balls can end up year round and not only in fall. One just missed this morning and hit the shutter. :D
