It tends to be a lot sunnier in say California, and the sun will also be higher in the sky in summer and lower in winter. Has the glare been worse in one season than another?
Oh, anyone who does find the glare a problem, aftermarket dark-colored dash covers are widely available for under $100.
I do not wear polarized sunglasses, although I have blue eyes, which are naturally more photo-sensitive than say brown eyes. I would think that would make me more disposed to notice the glare, not less. But it's certainly a variable.
Indeed, blue-eyed people are more sensitive to light than brown-eyed. For anyone interested: https://www.essilorusa.com/newsroom/sensitive-to-light-blame-your-blue-eyes

I was referring mainly to the number of days of sun, not the amount when sunny. However, the bolded
statement isn't strictly correct. See: https://en.wikipedia.org/wiki/Polar_climate#/media/File:Oblique_rays_04_Pengo.svg
There's about 9 degrees of difference in the latitudes between Syracuse and L.A. (ca. 5.3 deg. in S.F.), and while fairly small, it does mean that the sunlight reaching you has to go through a bit more atmosphere.
GetOffYourGas wrote:The sun certainly is higher in the sky at more southern latitudes and that could be a factor. The glare does seem to be worse in the summer than the winter, which of course is when the sun is higher in the sky. And it's more noticeable at noon than at say 6pm. So maybe you're onto something there.
I suspect it's a combination of the above factors with the angle of the Bolt's windshield. For some related info pertinent to my AE days, see https://solarprofessional.com/articles/design-installation/evaluating-glare-from-roof-mounted-pv-arrays/page/0/1#.WyQu-ejwbEY
Then there are other physical factors:
Halos and glare can be caused by eye problems that keep the eye from properly focusing light onto your retina (the thin lining located in the back of the eye). Common eye problems that can cause halos and glare include:
Nearsightedness (difficulty seeing things far away)
Farsightedness (difficulty seeing things nearby)
Presbyopia (difficulty seeing things nearby due to aging)
Astigmatism (blurred vision due to irregular shape of the eye)
Someone who could benefit from prescription lenses but doesn't have them, or whose prescription is a bit out of date may be more sensitive to glare.
