    I am trying to find out what are the optimal prescription (or otherwise)
    eyeglasses for night driving. The problem is simple: on a dark road you
    usually stare in a brightly lit (by headlamps) area in front of your car as
    long as you're going straight. But when you start turning into the corner
    you have to look in the darkness. That wouldn't be that bad by itself, but
    the eyes are already used to relatively bright light of headlights and it
    takes them a while to adjust (of course, too long for actually seeing into
    the turn). I wonder if some kind of eyeglasses would do better in this
    conditions. For example, would lenses with transparency changing inversely
    with brightness help? (If such lenses exist)? I've tried to ask this
    question to local opticians, they tend to recommend anti-glare coating, but
    they can't explain why would it help in these circumstanes. So I've decided
    to turn to the usenet wisdom :)

    Thanks in advance,

    Ummm, back up a bit. The area illuminated by headlights
    is not "brilliantly" lit. Actually it is more likely less than
    adequately lit. reducing that effectiveness is to lessen
    the difference between that and unlit areas is probably
    not a good idea. There are cars that swivel the inboard
    headlight in the direction of the turn. Buying one of those
    might be a better idea.

    Buy one of those cars that have side lights. When you flip on the turn
    signal, the light on that side comes on also.

    The other solution, the one I use, is to not drive at night. Winter
    solstice is past. That means that it will start staying light later.
    This is a good thing for me.

    What are those cars? Not that I'm about to change the car just for that:)
    And I imagine you can just install extra lights, but would it be road-
    legal? I would think that if you meet another car in left turn you'll be
    blinding its driver?

    Anyway, it's probably better to post in *.autos.driving.* for some
    engineering solutions :)

    Just in case it didn't come out clear, I was talking about your own
    headlights and contrast betwen the area lit by them and the area remaining
    outside of the beams.
    Don't they react on UV rather than on an amount of visible light?
