I've pasted part of another post I just made below. I was very concerned about getting the right lens for low light in the glades, but still having one that was OK for bright, clear days. The lemon gun lens from Bolle does both very well, plus I really like the goggles otherwise.
Here's the excerpt:
I have a pair of Bolle Scream goggles with a lemon gun lens (38% light transmission) that retail for about $120 and I have absolutely no complaints after a year of skiing with them.
-They fit my face well
-The light transmission works well for cloudy days in the glades and bright days in the bowls
-They also clip together in the back, allowing me to use a goggle extender (I made from an old Bolle strap) with my helmet, without cutting the factory band.
-They allow quite a bit of peripheral vision, side to side and top to bottom
-They've never fogged
