to the  oncoming light - regardless of correct or incorrect aim.

I had always treasured my good vision. (NRA and US Army Expert) At about  
age 30, I noticed squinting at night to read unfamiliar street signs. So I 
got  my first distance vision glasses. The prescription changed slowly over 
the  years, and I eventually needed them for all driving and watching TV in 
the  family room. The real pain was sliding them into the helmet when racing 
or  autocrossing. About 8 years ago - age 54 - I had laser surgery on the  
outside of both eyes. Back to about 20/20 for distance, but the eyes were 
still  54 years old. So now I needed glasses to read - and for the computer. But 
I  could drive, and race and watch TV without the glasses. As they warn you 
 before the surgery, there were starlight effects on lights at night for a 
while.  But they went away, and I was/am very happy. Then, about 3 years 
ago,  I was driving at night and I noticed my right eye was, all-of-a-sudden, 
quite  sensitive to on-coming bright lights. Glare was much worse - but only 
in that  eye. I had an exam, and the Dr. told me that inside my eye, a 
little  fluid/gel-like substance had come a little loose, causing the diffusing 
of the  light. A sign of old age! (Thanks, Pal!) It had nothing to do with 
the  laser, that was on the outside. So I learned to favor my left eye for 
night  driving. Six months later, the other eye did the same thing. So now, 
although my  eyes are better focused than when I was 40 or 50, the general 
aging of my  eyes allows less light in, so I need better illumination than 
before, (Thank you  HIDs) and, conversely, glare from on-coming traffic, 
especially on  secondary roads, interferes more with my vision. Personally, I find 
less  on-coming glare problems with the "bluer" lighting of HIDs, and much 
worse with  the "yellower" lighting of incandescent lights. (especially poorly 
 aimed ones)
 
Of Course, that is only me. Your Visualage may vary. Remember all you young 
 guys, I am only the leading edge of the baby boomers, there will be a lot  
more of us coming along. 
 
And we will need better lighting to find our way!
