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.
Agreed...I use the sensor mirror all the time. Also in the NW...have been riding the pow at Alpy all week!
I may switch to orange lenses once the sun starts coming out more, but the sensor has been great fro the low light and night riding.
