My favorite is the Smith Sensor Mirror: Light rose base lens tint with a multi-layer mirror maximizes color definition and increases depth perception in varying levels of flat light conditions. 70% VLT.
I'm in the NW where we have low, flat light most of the time. These still cut it on our bluebird days, but might not if you get real bright sun. I'd suggest you find a similar lens from your manufacturer. The mirror tint is very light. Shay over on Snowboarding Through Fembot Eyes reviewed some goggles with this lens and also liked the versatility.
