Wow - well worth the extra cost! My original lenses were the Multilaser Ice which were fantastic for those Bluebird clear days.
BUT - where I ski, many days have a cap cloud at the top of the area meaning very flat lighting conditions on the upper mountain.
Lower down, the light improves to much brighter. What to do? Get these Photochromic lenses! They have a very wide range of light transmission and do it automatically. There’s simply not enough light transmission during those cloudy/snowy days for fixed-tint lenses and you lose definition of snow conditions - especially where moguls are concerned. These photochromic lenses do the trick for sure - very satisfied. Now, if Rudy would only make the next generation of goggle lenses magnetic so switching them out would be very quick….
