Ditto on the Serengeti recommendation. I find them particularly useful
late in the day when going "up sun" and for picking out the best
looking clouds through the haze. I've worn these for about 10 years
now; they replaced a pair of Ray Bans. I go with the Aviator Style -
geeky looking as all hell but wide enough to eliminate all but a small
amount of light infiltration from the sides. Those of you worried
about style can find Serengetis in other more fashionable
configurations.
