ANY tinted visor (including yellow) will cause a decrease in the amount of available light at night....almost always a bad thing. Do you wear glasses? Have you had your eyes checked by opthamologist (not an optomitrist) recently?
Night glare sensitivity is almost always a sign of other issues (night blindness, change in prescription, and host of medical conditions).

There are a couple of simple tests they have today for people with sensitivitiy....and easy fixes. Sometimes its as easy as increasing your vitamin A and/or Zinc intake...but get it checked out, first. Masking the underlying problem with a tinted visor doesn't fix the problem.
It also might mean making a habit change...training yourself to look away from approaching cars while "keeping track" of them in your peripheral vison. I find on long rides on dark back roads with no street lighting, especially in the rain, my eyes are more sensitive to oncoming traffic glare. It requires me to keep my head up, looking down the road further, and not focus on any one thing, but keep my eyes roving, so I don't focus in on one set of headlights.
Just a couple things to consider.
