Good sunnies to wear for flying?

[NOSIGN]

Leadsled,

thanks for the info on Martin X Hogan.

I have never been comfortable using plastic lenses; I feel that my vision becomes slightly distorted.

I am on to my second pair of Serengetti velocity, with a Ray Ban photochromatic in-between, and the Velocity are the best that I have worn.

They are clear and work well with change of lighting, especially low light.
