I avoid driving at night because of other people's headlights. My wife as well, and we're in our 40s. We've just assumed it's because our eyes are getting old and tired, but reading comments in this thread suggest it has less to do with that and more to do with an actual universal problem.

I've often thought of how cool it'd be to have a transparent LCD windshield that could use an eye tracking camera and a forward facing camera to calculate where to best draw an opaque circle in your line of sight so that'd it block the most intense points of light.

Sort of like holding your thumb up to block the light, just automatically and for multiple points of light.
