The reason for vision problems with blue lights---
---The shorter wavelength blue light scatters from mist, rain, snow, etc. and creates glare for both the rider and on coming drivers. This scattered light also tends to fill in shadow detail of road hazards making them harder to spot. (Skiers and snowboarders wear amber goggles to filter out blue light and increase the shadow contrast of uneven places on the snow. Yellow headlights and foglights have limited benefits in this way.)
4300°Kelvin is a good color temperature for good vision.
"Older people who are reasonable, good-tempered, and gracious will bear aging well. Those who are mean-spirited and irritable will be unhappy at every period of their lives.
"Let each of use properly whatever strengths he has and strive to use them well. If he does this, he will never find himself lacking."
Marcus Tullius Cicero
