What do you have for driving? Personally I have my normal glasses, some other glasses which are tinted to keep out the sun (i.e. sunglasses but in glasses frames) and most importantly some night driving glasses, which have a very mild yellowish tint to stop glare, but most importantly a very slightly more myopic (I think) prescription because your eyes change at the night.
I am legal to drive without any correction at all, and I'm not a border line case either, which is worrying...
Anyway it's cause of the night driving glasses I'm starting this thread, cause I thought some people may not be aware of the way yer prescription changes at night (and it's that that causes most dazzle, the yellow tint just makes you less bothered by it aiui)

I wear reading glasses but for anything more than a couple of feet away do not require glasses .
In the car , I have my Ray-Ban Aviators for bright conditions ; I used to have a pair of Zeiss Umbraumatic glasses for variable conditions until I sat on and broke them , have never found a replacement pair as I think they were discontinued .
I have never tried night glasses but must do so since I sometimes find glare from oncoming vehicles a problem during hours of darkness .

For daytime driving in conditions where strong glare is a problem, the lenses should be polarised. The polarisation filter dramatically reduces the glare from low angle sun (and from reflected light from the road surface which is especially a problem when wet or icy).
For night driving, some people (incorrectly) think that a yellow tint improves vision on road at night. The prevailing thought these days is that you shouldn't use any tinted glasses for night driving as it reduces transmittance.
Clear lenses with an Anti-Reflective coating are best for night driving.

I have one pair of brown tinted, polarised prescription glasses. I wear them for probably the majority of my daytime driving, even when it's not obviously bright - I find it makes it much easier to see, regardless.
I don't wear anything at night, my eyesight is more than good enough to meet the required standard without glasses on.

Prescription sunglasses with Hoya DriveWear lenses. Utterly brilliant.

Photochromic lenses, for example, do not darken in a car because the windscreen blocks out the necessary UV light. Polarised lenses will neutralise blinding glare, but they cannot adapt to varying light conditions. Traditional fixed tint sunglasses may not give adequate glare protection. Now, for the first time, polarisation and photochromic technologies have been combined in perfect harmony to allow complete control in changing light conditions.
I have them. They actually work. Genius.
