Blue headlights, most LED lamps and the SilverStar Ultra (4100K) all overwhelm your eyes' rod cells and stimulate the cone cells. This gives you the illusion that you're seeing things more clearly, but in actual fact, you're blind to anything that isn't in the direct path of your headlights.
Well, that's OK. I am blind to anything outside the direct path of my headlights, anyway, at night. My eyes contrast range cant handle the difference between the illuminated areas and the dark areas at night.
Isnt that the way everyone is?
No! Your eyes will adjust to the darkness if they're allowed time for the rod cells to recover from exposure to light with high color temperature.
A caveat to this is that lifetime exposure to UV rays (such as years of being outdoors in the sun without proper sunglasses) will cause the clear lens of your eye to darken. This will filter out much of the ambient light available at night and cause "night blindness". It's common in older folks and people with blue eyes as they age. Exposure to fluorescent lighting at work all day can also age your eyes.
