Another vote for Serengettis from me - hands down the best flying glasses I've ever had.
I used to have a pair of Randolphs and they were good.
Before that I had Raybans. They were ok, not as good as the Randolphs, but ok.
Then I tried my mates Serengettis with the drivers gradient lenses and what a difference......they really are the dogs preverbial.
I flogged the Randolphs to a friend and went straight out and bought the Serengetti velocity frames with drivers gradient lenses.
Can't praise them highly enough really - the world is a sweeter place when you look through them........cloud contrast is excellent........colour clarity seems unchanged..........I seem to be able to visually spot other traffic sooner.......I find my eyes get less tired.....all good stuff.
