I prefer Raybans. Get the B-15 gradient brown lenses with mirror
tinting. You get the benefits of enhanced contrast, decreased glare
from the mirror tint, and are able to easily see your instrument panel
because of the top-down color density gradient. Be aware that the
majority of Raybans come with color neutral (slightly green) G-15
lenses from the factory and that you need to specify B-15.

According to Rayban:B-15 Brown Lens - contrast enhancing lens that
sharpens details by blocking glare and a larger percentage of blue
light. Ideal for low light conditions. Excellent for enhanced vision
while driving and other fast-action activities.

Hi,
I have been flying with Serengetti sunglasses for many years in a
sailplane with a clear
canopy. I bought a LS6 with a light blue tinted canopy which make my
cockpit to dark
when in the shade of cloud. Suggestion are welcome to solve this
problem.
Regards,
