Altering the lens of a light to restrict its power is analogous to using high-performances tires and letting the air out of them for a better ride.
Then why is it that ALL automotive lights are actually required by law to have just the sort of optics that he's describing? Why not just tell them that they are just using lights that are too bright, and they need to reduce the brightness until it doesn't bother oncoming vehicles?
In Germany bicycle lights are required to have this sort of optics. Unfortunately in the US they're not, so we get whatever's cheap, which is plain flashlight round reflectors with no cutoff.
