I agree that many LED headlights are too bright (or, more commonly, poorly calibrated) however one thing which can significantly reduce glare is to clean your windshield properly at least once a year. Few people do this. When I say properly, I mean with a special purpose abrasive glass polish. This could take an hour or more to do well by hand but it should remove the near invisible (in standard lighting conditions) film which forms on the glass surface. This will also significantly improve visibility in heavy rain.
