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:
I thought this was the Tiger Woods joke thread...

Yeap -1/2. Yellow filters do not increase contrast under ANY conditions.
People just don't believe you when you tell them that!:hammer:

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.
Here we have a very strong opinion without any explanations on why and how. Basically just the old hat of promoting AR.

As for tints - why yellow? I wear a specific (not quite yellow) tint for night driving ( together with a lens specification which takes into account all other effects) - the difference in acuity, contrast sensitivity, edge and movement detection is remarkable. "Starring" of headlights (a columnated light source) is eliminated, ability to see in the distance is enhanced and my safety is much greater. .................
Oh - and I do have the instrumentation to test for these effects - so I can say with confidence that the effects are not imagined.
I am your honour guilty of wanting to see better!
Here is the opposite opinion with a lot of backup, like years of research and experience. I would suggest you to look at the following 2 websites to see which statement has more validity. Ian Jordan is a well known research optician.

I have to side with Ian on this one.

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
