Rick, the OEM's are going with the ridiculous, blinding LED or HID on all headlamps now, I feel your pain but there is a solution: Apply a 2x4" panel of electrician's tape to your windshield in the area of oncoming lights. If you get it in the right place you can hide behind it.
Will, the problem isn't cataracts, it's the effects of the surgery and implants after they are removed. Same thing with Lasik surgery, light sensitivity, especially at night, is significantly increased. Piercing blue headlamps are especialy painful. To make matters worse, stupid/incompetent/lazy drivers coupled with incomprehensible automatic headlamp controls makes for a 2/3 majority of drivers who run with their high-beams on all the time and that hurts me like hell even during the day. Pickup-trucks pulling trailers or weight in the bed, and/or with a "leveling kit" which raises the front and nobody bothers to re-adjust the headlamp through, make it so even the low-beams shine directly into the windshields of oncoming traffic. Motorcycles are also really bad about blinding drivers with poor lamp adjustment or running high-beams on all the time, I guess they just don't savvy that I can't see you if you BLIND me.
I have an interest in the LEDs for the "torch of God" effect which will enhance what I already do...carefully aim the left high-beam directly at oncoming drivers faces so my "DIM YOUR $@&$#&^# LIGHTS" blip has maximum effect.
