I've found some good looking Bolle prescription goggles at a decent price, but have the choice of lens colouring, with three colours, and a range of 75% (lightest) to 25% (darkest).
Grey - 75%
Grey - 55%
Grey - 25%
Brown - 75%
Brown - 55%
Brown - 25%
Yellow - 60%
I know that yellow lenses can help with contrast (which can be really useful in forested areas with lots of dense foliage), but I would also worry that it might make it harder to tell who is on which team at skirmishes, as it's generally signalled with a blue or red armband.
